Two identical stones, A and B, are thrown from a cliff from the same height and with the same initial speed. Stone A is thrown v
Taya2010 [7]

Answer:

Option A

Explanation:

This can be explained based on the conservation of energy.

The total mechanical energy of the system remain constant in the absence of any external force. Also, the total mechanical energy of the system is the sum of the potential energy and the kinetic energy associated with the system.

In case of two stones thrown from a cliff one vertically downwards the other vertically upwards, the overall gravitational potential energy remain same for the two stones as the displacement of the stones is same.

Therefore the kinetic energy and hence the speed of the two stones should also be same in order for the mechanical energy to remain conserved.

pishuonlain [190]

Answer:

<u>Mirrors</u>

Explanation:

In Solar thermal power generation system, mirrors are used to collect and focus sunlight  onto a fluid pipe to produce high temperature required to generate electricity.

There are two main components: mirrors capture and focus light onto a receiver. The heat transfer fluid is circulated in the receiver. Steam is produced which is converted to mechanical energy in a turbine. It powers a generator and electricity is produced.
