Explanation:
hope this helps ( not sure tho )
Before connecting the wires used to make an electromagnet, several steps are necessary. The steps are removing insulation from wire ends and cleaning and connecting the prepared wire ends.
First, the insulation surrounding the wire ends must be removed using a blade. Next, the exposed ends should be cleaned with a wire brush or sandpaper to eliminate any dirt or oxidation. Depending on the requirements, the wires can be twisted together for a temporary connection or soldered for a more secure joint. Lastly, the prepared wire ends are connected as needed to complete the circuit.
Therefore, these steps ensure that the wires are properly prepared, allowing for effective current flow and the formation of a functional electromagnet.

If Juan upgrades from a sports car to a large truck, what will happen to the
force needed to keep the truck going at the same speed? Use this
sentence frame
Answer:
The force will have to increase
Explanation:
Since Juan has upgraded from a sports car to a large truck, based on Newton's second law of motion, the force needed to keep the truck going at the same speed will have to increase.
According to Newton's second law "the force on an object is equal to the product of its mass and acceleration".
Force = mass x acceleration
A truck has a larger mass compared to a sports car.
By virtue of this, to make sure both automobiles attain the same speed, the force powering them to accelerate must be the same.
Therefore, the force from the engine must increase.

The net force acting on a Cessna 172 airplane has a magnitude of 1900 N and points in the positive x direction. If the plane has a mass of 860 kg, what is its acceleration?
Answer: 10.05m/s²
Explanation:
Force acting on the plane has a magnitude of 1900N.
Mass of plane = 860kg
We then calculate the acceleration which will be:
= 1900 / 860
= 2.21 m/s²
Since acceleration due to gravity is equal to 9.8m/s², then the net acceleration will be:
= ✓(2.21² + 9.8²)
= ✓(4.88 + 96.04)
=✓100.92
= 10.05m/s²

Which skateboarder has greater momentum?
a) Skateboarder A: mass = 60 kg; velocity = 1.5 m/s
b) Skateboarder B: mass = 50 kg; velocity = 2.0 m/s
Answer:
skateboard b
Explanation:
p=mv
skateboard a
p=(60kg)(1.5m/s)=90kg*m/s
skateboard b
p=(50kg)(2m/s)=100kg*m/s
Skateboarder B has the greater momentum because the momentum of A is 90 kg m/s and the momentum of B is 100 kg m/s so B has the greater momentum.
What is momentum?Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum. Check out Newton's laws of motion.
According to Newton's second law, if a particle is subjected to a constant force for a specific amount of time, the result of the force and time (referred to as the impulse) is equal to the change in momentum. On the other hand, a particle's momentum represents the length of time needed for a consistent force to bring it to rest.
According to the question,
For Skateboarder A :
momentum = 60 × 1.5
momentum = 90 kg m/s
For Skateboarder B :
momentum = 50 × 2
momentum = 100 kg m/s.
Hence, B has greater momentum than A.

Mr. Turner is driving through downtown Houston at 35 MPH (15.56 m/s). This is above the posted speed limit and there are cars parked alongside the curb in the lane next to Mr. Turner. Of course, a large delivery truck ahead looks like it is parked and driverless, but the driver's door swings open into the lane ahead of Mr. Turner. Mr. Turner's reaction time is 3/4th's of a second and the stopping distance at his speed is 1.7 meters. The driver exiting the delivery truck is 13.3 meters ahead. Can Mr. Turner stop in time? What is the vehicle's acceleration when the brakes are applied?
How far will the vehicle travel before Mr. Turner engages the brake?
(I need someone to explain this to me)
Answer:
Mr. Turner will not be able to stop in time.
a = - 71.2 m/s²
s₁ = 11.67 m
Explanation:
Since, Mr. Turner is driving at 45.56 m/s and his reaction time for applying brakes is 3/4th of a second. So, the distance covered by car in this time will be:
s₁ = vt
where,
s₁ = distance covered by car before applying brakes = ?
v = speed of car = 15.56 m/s
t = reaction time = 3/4th of second = 0.75 s
Therefore,
s₁ = (15.56 m/s)(0.75 s)
s₁ = 11.67 m
and the distance required for the car to stop after applying brakes is:
s₂ = 1.7 m
So, the total distance traveled by car before stopping will be:
s = s₁ + s₂
s = 11.67 m 1.7 m
s = 13.37 m
since, the driver was 13.3 m ahead.
Therefore, Mr. Turner will not be able to stop in time.
To find the deceleration of Mr. Turner after applying brakes we use 3rd equation of motion:
2as₂ = Vf² - Vi²
where,
a = deceleration = ?
Vf = Final Velocity = 0 m/s
Vi = Initial velocity = 15.56 m/s
Therefore,
2a(1.7 m) = (0 m/s)² - (15.56 m/s)²
a = - (242.1136 m²/s²)/3.4 m
a = - 71.2 m/s²

Two identical spheres (of equal mass) a distance of 10 meters apart exert a force of gravity of 0.00050 N on each other. What are their masses?
Answer:
The gravitational force between two objects is written as:
F = G*m1*m2/r^2
Where:
G = 6.67*10^(-11) m^3/kg*s
m1 and m2 are the masses of the objects.
r is the distance between the objects.
In this case, we know that:
F = 0.0005 N
r = 10m
and because the two spheres are identical, we have that:
m1 = m2 = M
then we have the equation:
0.0005 N = (6.67*10^(-11) m^3/kg*s)*(M^2/(10m)^2)
0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) = M^2
√( 0.0005 N*(10m)^2/(6.67*10^(-11) m^3/kg*s) ) = M = 27,379.3 kg
The mass of each sphere is 27,379.3 kg
one side of a copper sheet is highly polished and the other side is painted matt black. the copper sheet is very hot and placed in a verticle position. a student places her hands at equal distances from the sheet. explain why her hands are not heated by convection
Answer:
Because radiation does not require material medium for its propagation.
Explanation:
Radiation is one of the types of modes of heat transfer that takes place majorly in gases. Heat energy can be transferred through gases by radiation without heating up the intervening medium. Even, if the available molecules of gases are evacuated, the heat energy would propagate.
Thus, student's hands were not heated by convection since convection is a mode where material medium is required for propagation of heat energy.

Chemical reactions always involve changes in energy.
Energy must be taken away to break bonds
Forming bonds releases energy
Energy is released in chemical reactions
Answer:
Chemical reactions always involve changes in energy.
Energy is released in chemical reactions
Explanation:
Chemical reactions involves the formation and breaking of bonds by the combination of atoms in a system.
Chemical reactions always involve changes in energy which can be exothermic or endothermic in nature. When bonds are broken energy is always released, bond dissociation is an exothermic process. When bonds are formed, energy is used up and this process is an endothermic one.A certain AM radio wave has a frequency of

A 49 kg person is being dragged in their sleeping bag to the lake by a 593 N
force at an angle of 30°. If the person accelerates at a rate of 0.57 m/s2, how
much resistive forte (force of friction) is acting on them?
Answer:
485.62 N
Explanation:
To obtain the magnitude of unbalanced forces acting on the body;
Unbalanced Force = Horizontal Component of Applied Force - Frictional Force
Frictional Force = Horizontal Component of Applied Force - Unbalanced Force
f = frictional force = ?
F = Applied force = 593 N
m = mass of person = 49 kg
a = acceleration = 0.57 m/s²
θ = Angle with horizontal = 30°
Hence;
Horizontal Component of Applied Force = (593 N)(Cos 30°)
Unbalanced Force = (49 kg)(0.57 m/s²)
f = (593 N)(Cos 30°) - (49 kg)(0.57 m/s²)
f = 513.55 N - 27.93 N
f = 485.62 N

What is the thermal energy of an object? Question options: the total potential temperature of its particles the total potential energy of its particles the total kinetic energy of its particles the total kinetic and potential energy of its particles
Answer:
the total kinetic and potential energy of its particles
Explanation:
In every object, there are two types of energy which can be found inside them-Kinetic and Potential Energy. For example, a solid object placed on a stationary table has a potential energy due to the vibration of the molecules of the object.
As the object is moved across the table, it has kinetic energy. The combination of both energy is known as thermal energy. An increase in both energy leads to increase in the thermal energy of a given object.

Answer:
Given: 6 questions with certain values of mass and acceleration.
To find: The amount of force?
Solution:
An object with a mass of 2.0 kg accelerates 2.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
F = m x a = 2 x 2 = 4 N
An object with a mass of 5.0 kg accelerates 8.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
F = m x a = 5 x 8 = 40 N
An object with a mass of 1500 g (grams) accelerates 10.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
Now in this mass is in grams, so converting it kg, we get:
1500/1000 kg = 1.5 kg
F = m x a = 1.5 x 10 = 15 N
