You toss a coin straight upward in a train which is moving at a constant velocity. if the air friction is negligible, the coin will land (a) in front of you (b) behind you (c) on your hand (d) at either in front of you or behind you

option (c)

Explanation:

As you toss the coin, it will land in your hand. It is because the coin has same horizontal velocity as you and as that of train. So the horizontal distance traveled by you and the coin remains same and thus it will land in your hand.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
