Answer: The correct option is A.

Explanation:

Sound is a longitudinal wave. In longitudinal wave, the particles vibrate parallel to the direction of the propagation of the wave.

Sound wave consists of compression and rarefaction.

It needs medium to travel. It can travel in solid, liquid and gas. Denser the medium, more will be the speed of the sound.

Sound wave travels faster in solid in comparison to liquid.

In the given problem, when traveling from air to a solid then the speed of the sound wave will speed up.

Therefore, the correct answer is A.

Answer:

P = 360 Watts

Explanation:

Given that,

The weight of a student, $F=5.4\times 10^2\ N$

It takes 15 seconds to run up a hill.

The top of the hill is 10 meters vertically above her starting point.

We need to find the power develop during her run. We know that te power developed is given by :

$P=\dfrac{W}{t}\\\\P=\dfrac{mgh}{t}\\\\P=\dfrac{5.4\times 10^2\times 10}{15}\\\\P=360\ W$

So, the power develop during her run is 360 W.
