Appliances connected so that they form a single pathway for charges to flow are connected in a(n)
Answer:A. Series circuit
#CARRYONLEARNING #STUDYWELLAppliances connected so that they create a single pathway for charges to flow are connected in a series circuit. Therefore, option (A) is correct.
What is the resistance of resistors connected in series?In a series combination of appliances, they are connected end-to-end. Consider two resistors, R₁ and R₂ which are connected in a series combination then their effective resistance can be given by:
Total Resistance of the series circuit, R = R₁ + R₂
In a series combination, the current flows through one appliance and then through another appliance. The same current flows through each appliance in one direction. The total voltage of the series circuit is equal to the sum of all the voltage drops across all appliances.
A potential difference of the series circuit, V = V₁ + V₂
Therefore, when appliances are connected in a series circuit they form a single pathway for charges to flow.

16. If a car starts from rest and reaches a velocity of 50 m/s in 8 seconds, what was the
acceleration?
Answer:
The answer is (60 mph - 0 mph) / 8s = (26.8224 m/s - 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared.
A ball falls from a tower
a) The two forces acting on the tennis ball are equal and opposite. What is the resultant force
?acting on the ball
Answer:
Zero
Explanation:
The resultant force acting on the ball would be zero.
Since only two forces were acting on the tennis ball and these forces negate and cancel each other in magnitude, the resultant effect on the tennis ball would be zero.
Assuming that one of the forces is 5N and acting from the positive side and the other force is also 5N but acting from the negative side.
Resultant = -5 + 5 = 0 N

A 30.0 kg box is placed on a 3.00 m tall shelf. What how much work was done on the box?
Answer:
W = 882.9[J]
Explanation:
In order to be able to calculate the work, we must first calculate the force necessary to lift the box. Since the necessary force is equivalent to the weight of the box, we can determine the weight of the box by means of the product of mass by gravitational acceleration.
[tex]w = m*g\\[/tex]
where:
w = weight [N]
m = mass = 30 [kg]
g = gravity acceleration = 9.81 [m/s²]
[tex]w = 30*9.81\\w = 294.3 [N][/tex]
Now, the work can be calculated multiplying the force (weight) by the distance [m]
[tex]W = w*d\\W = 294.3*3\\W=882.9[J][/tex]

Which correctly lists the three features shown in the photo?
folds, strike-slip faults, and anticlines
anticlines, synclines, and folds
synclines, normal faults, and strike-slip faults
normal faults, folds, and anticlines
The correctly lists the three features shown in the photo is folds, strike-slip faults, and anticlines.
What is the difference between folds and failures?Modern folds are those that emerged recently (on the scale of geological periods), that is, in the Tertiary Period (between 65 million and 2.5 million years ago). Faults are geological structures that originate from vertical (top-down) or inclined internal forces.
The transcurrent fault – also called horizontal fault – occurs when there is displacement in the horizontal plane between the two blocks, being more common in zones where two tectonic plates meet, when these also move horizontally.

Which refers to the change of pitch heard when the source of the sound approaches and then moves away from a stationary person? Doppler effect volume resonance effect vibration
The Doppler effect is the change of pitch heard when the source of the sound approaches and then moves away from a stationary person. So, the correct option is A.
What is Doppler effect?The Doppler effect or Doppler shift is defined as the phenomenon observed when a source of waves is moving with respect to an observer. For example, an ambulance passing us with the sound of its siren is a common physiological demonstration of the Doppler effect.
The frequency increases when the listener and the source are approaching each other, while the frequency decreases when the listener and the source are moving away from each other. The Doppler effect is the change of pitch heard when the source of the sound approaches and then moves away from a stationary person.
Therefore, the correct option is A.

a.) Determine the work done by Zach on the bull.
Explanation:
Work done is a physical quantity that is defined as the force applied to move a body through a particular distance.
Work is only done when the force applied moves a body through a distance.
Work done = Force x distance
The maximum work is done when the force is parallel to the distance direction.
The minimum work is done when the force is at an angle of 90° to the distance direction.
So to solve this problem;
multiply the force applied by Zack and distance through which the bull was pulled.

Answer:
(1) The relationship between the altitude height, 'h', and the orbital speed, [tex]v_{orbit}[/tex], of the satellite is an inverse relationship
[tex]v_{orbit}[/tex] = 1/(h + R)
(2) The height of the satellite, is approximately 24,442 meters
(3) Please find attached the drawing showing the two lines that indicate the direction of the gravitational force on the satellites created with Microsoft Visio
Explanation:
(1) From the given data table, as the altitude increases, the orbital velocity decreases, therefore, the relationship between altitude, 'h', and orbital velocity, '[tex]v_{orbit}[/tex]', is an inverse relationship which can be expressed as follows;
[tex]v_{orbit} = \sqrt{\dfrac{G \cdot M}{r} }[/tex]
Where;
G = The universal gravitational constant
M = The mass of the Earth, or planet about which the satellite orbits
r = The distance between the center of the planet and the satellite = h + R
R = The radius of the planet
When [tex]v_{orbit}[/tex] = 27,500, h = r - R = 1000
We have;
[tex]v_{orbit}[/tex]² ∝ 1/r
[tex]v_{orbit}[/tex]² = k/r = k/(R+ h)
When, [tex]v_{orbit}[/tex]² = 27,500² = 756,250,000
r = h + R = 1000 + R
∴ 756,250,000 = k/(1000 + R)
(1,000 + R) × 756,250,000 = k
When, [tex]v_{orbit}[/tex]² = 18,000² = 324,000,000
r = h + R = 10,000 + R
∴ 324,000,000 = k/(10,000 + R)
324,000,000 = ((1,000 + R) × 756,250,000)/(10,000 + R)
∴ 324,000,000×(10,000 + R) = (1,000 + R) × 756,250,000
R × (756,250,000 - 324,000,000) = 324,000,000×10,000 - 1,000 × 756,250,000
R = (324,000,000×10,000 - 1,000 × 756,250,000)/(756,250,000 - 324,000,000) = 5746.09600925
R = 5,746.09600925
k = (1,000 + R) × 756,250,000 = (1,000 + 5,746.09600925) × 756,250,000 = 5.1017351 × 10¹²
k = 5.1017351 × 10¹²
(2) When, [tex]v_{orbit}[/tex] = 13,000 m/s, we have;
13,000² = 5.1017351 × 10¹²/(5,746.09600925 + h)
∴ 5,746.09600925 + h = 5.1017351 × 10^(12)/(13,000²) = 30187.7816568
h = 30187.7816568 - 5,746.09600925 = 24,441.6856476
The height of the satellite, h ≈ 24,442 meters

20) The four states of matter are;
a) Solids
b) Liquids
3) Gas
4) Plasma
21) The total number of atoms in the product is 2.7099 × 10²⁵ atoms.
Explanation:
14) The left side of the chemical equation is the reactant
15) The coefficient is the number in font of the formula, here, the coefficient of the reactant C₁₂H₂₂O₁₁ is 1 .This is a precipitation reaction equation
16) The number 11 in front of the formula, H₂O, is called a coefficient
17) On mole of a substance is defined as containing one Avogadro's number, [tex]N_A[/tex] of molecules
[tex]N_A[/tex] ≈ 6.022 × 10²³ mol⁻¹
In the reactant, C₁₂H₂₂O₁₁, there are 11 elements of oxygen in one mole of the reactants, which gives 11 × 6.022 × 10²³ = 6.6242 × 10²⁴ atoms of oxygen in one mole of the reactants
18) The right side of the chemical equation is called the product
20) The four states of matter are;
a) Solids
b) Liquids
3) Gas
4) Plasma
21) The number of elements on the product side are;
12 Carbon + 22 Hydrogen + 11 Oxygen = 45 Elements total
However, given that there are 12 moles of carbon, we have;
12 × 6.02 × 10²³ = 7.2264 × 10²⁴ atoms of carbon
For hydrogen, we have;
22 × 6.02 × 10²³ = 1.32484 × 10²⁵ atoms of hydrogen
For oxygen, we have;
11 × 6.02 × 10²³ = 6.6242 × 10²⁴ atoms of oxygen
The total number of atoms in the product is 7.2264 × 10²⁴ + 1.32484 × 10²⁵ + 6.6242 × 10²⁴ = 2.7099 × 10²⁵ atoms.
A north magnetic pole is facing another north magnetic pole with a distance x
. If the distance between the poles becomes 1/2x
, what happens to the magnitude of the field energy between them?(1 point)
The field energy will gradually dissipate until it reaches zero.
The field energy will remain unchanged.
The field energy will decrease.
The field energy will increase.
Answer:
Option 4 (The field energy will increase) is the right response.
Explanation:
Whereas the power kept secure in either an attribute has been collected, the artifact would be decided to push throughout the straight line that induces the electrostatic repulsion to greatly reduce. This same power generated will indeed be significantly decreased as well as supplanted by the power generation of the motion. Sometimes when magnetic poles figure together including poles, this same energy rendered inaccessible would then greatly reduce if those who keep moving off from each other. So our policy requires that perhaps the magnets would be tried to push throughout a position that reduces the energy consumed. That is, they're being allowed to force apart.All those other alternative solutions aren't closely linked to the example in question. Therefore the choice above is the right one.

Which of the following is NOT a criteria for a celestial object to be a planet?
-The object has cleared the neighborhood around its orbit of smaller objects.
-The object is in orbit around the Sun.
-The object has a nearly spherical shape.
-The object must be massive enough have a gravitational pull on the sun.
Answer:
The option which is not a criteria for a celestial object to be a planet is;
The object must be massive enough have a gravitational pull on the Sun
Explanation:
There are three criteria for a celestial object to be classified as a planet including;
1) The object's orbit is around the Sun
2) The shape of the object is nearly round due to its mass which is capable of assuming hydrostatic equilibrium
3) Other smaller objects in the neighborhood around the object has been cleared by the object
Therefore, the option which is not a criteria for a celestial object to be a planet is that it must be massive enough to have a gravitational pull on the Sun as every two objects in the Universe share a common gravitational pull according to Newton's Law of Gravitation.
Calculate the temperature change when 1000J of heat is supplied to 100g of water.
Please explain
Explanation:
Given
heat supplied (Q) = 1000 J
mass(m) = 100 g = 0.1 kg
specific heat capacity of water(s) = 4200 J/kg°C
change in Temperature (dt) = ?
We know we have the relation
Q = m * s * dt
Or, 1000 = 0.1 * 4200 * dt
Or, 1000 = 420 dt
Or, dt = 1000/ 420
Therefore dt = 2.38°
Hope it will help :)
The temperature changes when 1000J of heat is supplied to 100g of water is dt = 2.38°
What is temperature?The average kinetic energy of a system is measured by its temperature. The kinetic energy of a system starts to rise as the particle's velocity increases, which raises the system's temperature.
The energy that is transferred when two bodies with different surface temperatures come in touch is referred to as heat.
The change is when 1000J of heat is supplied to 100g of water.
Given that:
heat supplied (Q) = 1000 J
mass(m) = 100 g = 0.1 kg
specific heat capacity of water(s) = 4200 J/kg°C
Change in Temperature (dt) = ?
We know we have the relation
Q = m x s x dt
Or, 1000 = 0.1 x 4200 x dt
Or, 1000 = 420 dt
Or, dt = 1000/ 420
Therefore, the temperature changes when 1000J of heat is supplied to 100g of water is dt = 2.38°.

Dana pulls a spring with a spring constant k=300 N/M, stretching it from its rest length of 0.40 m to 0.50 m. What is the elastic potential energy stored in the spring?
Answer:
[tex]1.5\:\mathrm{J}[/tex]
Explanation:
The elastic potential energy of a spring is given by the following:
[tex]PE_s=\frac{1}{2}k\Delta x^2[/tex], where [tex]k[/tex] is the spring constant and [tex]\Delta x[/tex] is displacement.
The displacement of the string is [tex]0.50-0.40=0.10\: \mathrm{m}[/tex].
Plugging in our given values, we get:
[tex]PE_s=\frac{1}{2}\cdot300\cdot0.10^2=\fbox{$1.5\:\mathrm{J}$}[/tex].
The elastic potential energy stored in the spring is 1.5 joule.
What is potential energy?Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases.
If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised. Potential energy is a characteristic of systems rather than of particular bodies or particles.
Spring constant of the spring : k = 300 N/m.
Initial length of the spring = 0.40 m
Final length of the spring = 0.50 m.
Hence, stretching of the spring: Δx = 0.50 m - 0.40 m = 0.10 m.
So, the elastic potential energy stored in the spring is = 1/2 × k × Δx²
= 1/2 × 300 × (0.10)² joule
= 1.5 joule.

7. Mac and Tosh are arguing about the track design. Mac claims that the car is moving fastest at point F because it is furthest along the track Tosh disagrees, claiming that the car moves fastest at point F because point F is at the lowest height Who do you agree with? Make a modification of the track design for point F and gather some evidence to support one claim or the other. Then discuss what changes you made, what observations were made, and the reasoning that supports one of the claim of either Mac or Tosh.
Answer:
Tosh is correct.Swap the locations of points B and F on the track and gather speed data. If Mac is correct, the speed at F (closer to the start) should be lower. (It will not be, confirming Tosh's claim.)Explanation:
The total energy of the car is continuously being exchanged between potential energy and kinetic energy as the car moves along the track. Neglecting energy loss due to friction, the kinetic energy will be greatest when the potential energy is least, at the lowest point on the track. As a consequence we agree with Tosh that the speed will be greatest at F because it is the lowest point.
__
If the track were modified to move the lowest point nearer the start, say by interchanging points B and F, then data could be gathered to show whose theory is supported. The evidence needed is the speed of the car at the new location of point F. Tosh's argument is supported if the speed at the new point F is substantially the same.
How does attachment affect exploration? Be sure to include findings from both Harlow and Ainsworth in your response.
Answer:
Attachment can affect many things. When you go back to the experiment, you see that they are testing 4 monkeys. They want to see if they would go to the cloth mother or the wire mother. But that is just the base of the experiment. Once the monkeys pick the mother, they have attached themselves to the mother, because animals will pick what is mother, because once you are born, the "hunger games" begin in the wild. They will stay by their mother's side until they are grown and ready to go on their own. When you think about this whole experiment, you know that this experiment was designed as a test of the relative importance of contact comfort. They could have picked any animal for this, and the outcome would have been very similar because as a baby you need to find things that you trust and that is your mother.

Explanation:
Waves interact with objects and other waves. Thus, waves are used on objects such as mobile phones and can be transformed from one form to another.
There are various types of waves in our physical environment such as gamma rays, x-rays, ultraviolet waves, radio waves etc.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data. Some examples of communication technologies that uses radio waves are radio set, mobile phones, television etc.

Explanation:
You weigh 620 N. What would you weigh if the Earth were three times as massive as it is and its radius were four times its present value? Answer in units of N
Answer:
if
Explanation:
weight is the force of gravity on a mass; the force of gravity is
F = G M m/r^2
F is grav force
G is the newtonian gravitational constant = 6.67 x 10^-11 Nm^2/kg^2
M=mass of the earth
m=mass of the object
r= radius of the earth
if the mass of the earth increases by a factor of 6, this will tend to increase the grav force by a factor of 6
if the radius increases by a factor of 5, this will change the grav force by a factor of 1/5^2 = 1/25
the total effect is 6/25 = 0.24; therefore, your weight would be 0.24 * 620N = 149N
A body with mass 2 kg absorbs heat 418.4J when its temperature raises from 293K to 343K . What is the specific heat of the body?
Answer:
C M (change in T) = heat absorbed thermal equation for heat gained
C = 418.4 J / (2 kg * 50 deg K) = 4.184 J / kg * deg K specific heat
Note: 1 gm =.001 kg
So C = .004184J / gm * deg K
Also, 1 J = .239 cal so in conventional terms
C = .001 cal / gm deg K (very low, water would be 1 cal / gm deg C
