Answer:
A. whenever there is an opportunity for energy dispersal, the energy always spreads out
Explanation:
Answer:
B
Explanation:
Inert means it does not react with other things like oxygen ( to make oxide) or tarnish etc
Kinetic energy is equivalent to .5*(mass)*(velocity)^2
The mass should be in kilo grams and the velocity in meters per second.
Let me know if you need more help with it.
Answer:
Yes, this is true.
-- While the apple is falling, the same gravitational force acts on both the apple and the Earth.
-- The mass of the apple is somewhere in the neighborhood of 1/4 kg.
-- The mass of the Earth is about 5.972 x 10²⁴ kg.
-- Since the Earth has roughly 2.389 x 10²⁶ times as much mass as the apple has, the apple has roughly 2.389 x 10²⁶ greater acceleration than the Earth has, and moves roughly 2.389 x 10²⁶ times as far down as the Earth moves up, before they smack together.
-- That's why you don't notice the Earth's motion.
-- Also, you're standing on the Earth, moving up with it, toward the apple. Maybe it would be different if you were sitting on the apple, riding it down to the ground, and you were able to notice the motion of the ground coming up to meet you at a speed that's 0.00000000000000000000000000419 of YOUR speed.
