Answer:answer is B

Explanation:

Answer:

B.

Explanation:

This is because if it has a long half-life then there will be enough rock left to be able to determine the age of the rock. It is not A. because if it has a long half-life there would be part of the substance left to determine the age. It is not C. because in order to study the substance, there must first be a substance left to study.

Answer:

2 pc

Explanation:

The parallax angle is the angle of the earth at different times in a year relative to a given closest star.

P = [tex]\frac{1}{d}[/tex]

where p is the parallax angle, d is the distance between the earth and the star

Since p = 0.5 arcsec, then;

d = [tex]\frac{1}{p}[/tex]

  = [tex]\frac{1}{0.5}[/tex]

  = 2

d = 2 pc

The star is 2 parsec away from the earth.

Answer:

The arrows always start at the magnet's north pole and point towards its south pole. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).

Explanation:

if you take the total amount of ounces the carton holds (128 ounces)and divide it by the number of ounces the son consumes per serving(4ounces) you will get the total amount of servings(32servings)

Answer:

F = 12000 N = 12 KN

Explanation:

First we need to find the acceleration of the bad boys by using second equation of motion:

s = Vi t + (1/2)at²

where,

s = distance covered = 5 m

Vi = Initial Velocity = 0 m/s

t = time taken = 0.5 s

a = acceleration = ?

Therefore,

5 m = (0 m/s)(0.5 s) + (1/2)a(0.5 s)²

a = 2(5 m)/(0.5 s)²

a = 40 m/s²

Now, we calculate the force applied by Newton's Second Law:

F = ma

where,

F = force = ?

m = mass of bad guys = 300 kg

Therefore,

F = (300 kg)(40 m/s²)

F = 12000 N = 12 KN

0,15 m

Explicación:

Paso uno:

dado

Fuerza F = 250N

diámetro d1- 16 cm am = 0.16 m

A1 = πd1 ^ 2/4 = 3.142 * 0.16 ^ 2/4

= 0.02 m ^ 2

Carga L = 3500N

A2 =?

Segundo paso:

sabemos que la presión aplicada a un extremo para levantar una carga en el otro extremo se expresa matemáticamente como

F1 / A1 = F2 / A

sustituir

250 / 0.2 = 3500 / A

cruzar multiplicar

A2 = 0.02 * 3500/250

A2 = 70.3 / 250

A2 = 0.28

sabemos que área = πd ^ 2/4

0.28 = πd2 ^ 2/4

0.28 = 3.142 * d2 ^ 2/4

0.28 * 4 / 3.142 = d2 ^ 2

0.36 = d ^ 2

d = √0.36

d = 0.6 m

el diámetro debe ser de 0.6 m

hello your question is incomplete attached below is the complete question

answer : [tex]F_{E} > F_{F} > F_{A} = F_{B} > F_{C} =F_{D}[/tex]

Explanation:

The explanation behind the reasoning is attached below

Ranking the magnitude of the net electric force on the lower-left particle from the greatest to the least

[tex]F_{E} > F_{F} > F_{A} = F_{B} > F_{C} =F_{D}[/tex]

The magnitude of the net electric force on the lower-left particle. greatest to least in order of [tex]\rm F_E > F_F > F_A= F_B > F_C=F_D[/tex]

The electric force between the two charges is directly propotional to the product of the charge and inversly propotional to the square of the distance between them.

The electric force for each case found as;

[tex]\rm F_1 = \frac{2K q^2}{q^2} \\\\ \rm F_2 = \frac{2K q^2}{q^2} \\\\[/tex]

[tex]\rm F_3= 2 m \\\\ \rm \rm F_4= 4\sqrt{3} m\\\\ \rm F_5= 4m[/tex]

Hence the magnitude of the net electric force on the lower-left particle. greatest to least in order of [tex]\rm F_E > F_F > F_A= F_B > F_C=F_D[/tex]

Answer:

Acceleration, [tex]a=23\ m/s^2[/tex]

Explanation:

Given that,

The statue of Liberty is at a height of 46 m.

Jean Grey needs to fly from  rest on the ground to the top of the Statue of Liberty (46 m) in 2.0  seconds.

We need to find her minimum average acceleration during her  ascent. Let it is t. Using the second equation of motion to find it.

[tex]h=ut+\dfrac{1}{2}at^2\\\\h=\dfrac{1}{2}at^2\\\\a=\dfrac{2h}{t^2}\\\\a=\dfrac{2\times 46}{(2)^2}\\\\a=23\ m/s^2[/tex]

So, the constant acceleration is [tex]23\ m/s^2[/tex] for the entire distance.

Answer:

Answer: A. [tex]\vec r = 4\hat x+2\hat y[/tex]

Explanation:

Sum of Vectors

The vectors plotted in the graph are arranged using the head-to-tail method, i.e. placing the tail of the second vector at the head of the first vector. The head of the second vector indicates the sum of both vectors.

From the graph, we can see the head of the second vector lies in the point of coordinates (4,2).

This vector is represented as:

[tex]\vec r = 4\hat x+2\hat y[/tex]

Answer: A. [tex]\mathbf{\vec r = 4\hat x+2\hat y}[/tex]

Answer: The correct option is C ( Chemical energy > Electrical energy > Sound energy)

Explanation:

Energy is defined as the capability or ability to perform work. It is measured in joules. It is a scalar quantity ( that is, fully described by its magnitude).

The principle of conservation of energy states that in a closed system, energy can neither be created nor destroyed during transformation. Although energy can be transformed so that the total energy of a given system always remains constant. The different forms of energy includes:

--> mechanical energy

--> Chemical energy

--> Heat energy

--> sound energy

--> electrical energy

--> sound energy

To be able to create a circuit that will produce siren sounds, a source of power supply will be needed. This would be derived from a battery cell( Chemical energy). This supplies current (electrical energy)to the sound system of the circuit to produce the siren sounds heard(sound energy). Therefore the energy transformation is from CHEMICAL ENERGY to ELECTRICAL ENERGY to SOUND ENERGY.

Answer:

1. The velocity decreases, and the kinetic energy decreases.  

2. an increase in temperature difference between the inside and outside of the building

3. The total kinetic energy remains the same.

4. 76,761 J

5. The energy loss must increase.

kinetic energy and thermal conductivity processes allow the correct answers to the questions are:

4. The answer for the total kinetic energy correct is:   D. 17761 J

5. the answer is:   C. The energy loss can increase or decrease.

4. Kinetic energy is due to the motion of bodies and is given by the relation  

           K = ½ m v²

Wher k is de kinetic energy, m the mass and v speed.

Let's look for the kinetic energy of the bullet

           K₂ = ½ 18 23²

           K₂ = 4761 J

They indicate the kinetic energy of the cannon is K = 72000 J, they ask the energy at total kinetic energy is

           [tex]K_{total}[/tex] = K + K₂

           K_{total} = 72000 + 4761

           K_{total} = 76761 J

When checking the answer, the correct one is

              D. 76761 J

5. In modern houses and systems, insulation is created to maintain heat and reduce losses

            P =[tex]\frac{A \Delta T}{R}[/tex]  

Where P is the heat flux, A the insulated area, ΔT the temperature difference and R the relationship between the thickness of the insulation and its thermal conductivity.

In this case they indicate that the flow increases and the isolated area increases. We have several possibilities

In this case it indicates that the two increases, therefore the heat requests can increase or decrease

The correct answer is :

  C. The energy loss can increase or decrease.

With kinetic energy and thermal conductivity processes we can find the correct answers to the questions that are:

4. The answer for the total kinetic energy correct is:   D. 17761 J

5. the answer is:   C. The energy loss can increase or decrease.
