Gravitational Potential Energy (GPE) before fall = Kinetic energy on impact
GPE = mgh
GPE = 5kg x 9.8m/s^2 x 10m
GPE = 490 J
Kinetic Energy = 490 J
(This is assuming that gravitation field strength (g) is 9.8m/s^2, sometimes you may round this to 10m/s^2, therefore making the final result:
Kinetic energy = 500 J)
What is it asking? It is sort of blurry
Answer:
Option C
Explanation:
Visible telescopes are the telescopes which are sensitive in the spectrum of the light in the visible range.
The visible light telescopes are of three types out of which the reflecting telescopes uses the mirror so as to collect light as much as it can.
Convex mirror is used in such telescopes to collect all the light that falls on it and then the mirror reflects the light back to the focus.
Thus the mirror acts a bucket of light for its collection and the helps to form the world's largest visible light telescope.
Because of the tension of the rope, the force that the SUV exerts on the trailer is equal and opposite than the force that the trailer exerts on the SUV. This is explained in Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
