Why does time slow down for someone standing at the bottom of a mountain compared to time for someone at the top of a mountain?

The concept of time is influenced by the force of gravity. On a planet, gravity acts on every object within its gravitational field. The closer the object is to the surface of the planet, the greater infl...

How does temperature relate to the structure of solids and liquids?

Temperature is defined as the average kinetic energy of a substance, and it is what determines whether an object is a solid or a liquid. When the temperature is low, the average kinetic energy of the subs...

A 25 micro farad is charged until the potential difference across it is 500V. Calculate the charge stored at this moment.

The formula to be used here is C = Q / V. Where C = capacitance, Q = charge and V = potential difference. First we can put in the values to get 25 * 10^-6 = Q / 500. This can be rearranged to Q = 500 * 25...

Explain why atmospheric pressure decreases with increasing altitude. (3 marks)

Firstly, pressure is created by air molecules colliding with a surface. At an increased altitude there are fewer air molecules, and therefore a larger average distance between them. This means at this hig...

A ball is released from height h w.r.t. the ground. Draw a qualitative height versus time diagram of the ball bouncing in a non-ideal case.

In a non-ideal case, there will be energy loss in heat when the ball touches the ground. In particular:Kn=aKn-1, where Kn-1...
