Gravitational energy is a form of potential energy because it is dependent on the mass of an object and needs to be calculated for the specific object.
Non- mechanical wave does not need matter to carry energy.
e.g:- Light
Answer:
0 m/s
Explanation:
Average velocity of an object is given by the net displacement divided by time taken. Displacement is equal to the shortest path covered by the object.
In this problem, a player runs the length of the 30-meter court and back. The player does this three times in 60 seconds.
As the player runs the court and returns to the original point. It would mean that the shortest path covered is 0.
Average velocity = displacement/time
v=0/30
v = 0 m/s
Hence, the correct option is (1).
Answer:
The group of light rays is reflected back towards the focal point thereby producing a magnifying effect.
