A 5kg chunk of ice is sliding at 12m/s on the floor of an ice-covered valley when it collides and sticks to another identical chunk of ice that is initially at rest. Assume that the ice surface is frictionless. After the collision, the ice blocks slide partially up a hillside and then slide back again? (Hints: break down this problem into two parts - the collision and the behavior after the collision.)

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

learn it on the intertant so you can solve

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.
