Answer: A). Geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.

Explanation:

Geothermal energy is the energy which is obtain in the form of heat liberated from water released from the earth geosphere. The hot mantle causes the boiling of the groundwater which is liberated from the hot spring. It is a renewable source of energy which means it is obtained from resource which can be replenished and can be used again. This energy is used to generate electricity.

How was Einstein's theory that energy and mass are interchangeable eventually proven to be correct?

Pani-rosa [81]

Answer:

Stanley Eddington confirmed the theory by his observations and inferences using the solar eclipse

Explanation:

Albert Einstein proposed a theory that energy and mass are interchangeable; termed the theory of special relativity. This can be observed when an object moves with the speed of light. The theory states that all laws in physics are the same for all non-accelerating observers.

Thus,

E = m $c^{2$

This theory could not be proven over many years, therefore it was not fully accepted.

In 1919, Stanley Eddington confirmed the theory by his observations and inferences using solar eclipse. The theory is now very accurate at any given speed when gravitational force tends to zero. This has lead to other observations to prove Einstein's theory.

You’re driving your car towards an intersection. A Porsche is stopped at the red light. You’re traveling at 36 km/h (10 m/s). As

34kurt

Your position at time $t$ , relative to the stop line:

$x_1=-15\,\mathrm m+\left(10\dfrac{\rm m}{\rm s}\right)t$

The Porsche's position:

$x_2=\dfrac12\left(3\dfrac{\rm m}{\mathrm s^2}\right)t^2$

a. You pass the Porsche immediately after the time it takes for $x_1=x_2$ :

$-15\,\mathrm m+\left(10\dfrac{\rm m}{\rm s}\right)t=\dfrac12\left(3\dfrac{\rm m}{\mathrm s^2}\right)t^2\implies t=2.3\,\rm s$

at which point you both will have traveled 7.8 m from the stop line.

b. The equation in part (a) has two solutions. The Porsche passes you at the second solution of about $t=4.4\,\rm s$ , at which point you both will have traveled 29 m.

c. At time $t$ , the Porsche is moving at velocity

$v=\left(3\dfrac{\rm m}{\mathrm s^2}\right)t$

so that at the moment it passes you, its speed is 13 m/s, which is about 46.8 km/h and below the speed limit, so neither of you will be pulled over.
