1. oxygen is a very reactive element, which element in the atmosphere serves to dilute oxygen and
reduce its reactivity? a. nitrogen b. argon c. water vapor d. carbon dioxide
momentum of a body is defined as the product of its mass and velocity.
so, when an object is moving, it has momentum.
if and are the masses of objects a and b and are their initial velocities. so, their initial momentum will be:
if after collision it bounces back with same velocities, then final momentum becomes:
-ve sign shows that the motion is in opposite direction.
hence, its final momentum is in opposite direction of initial momentum.
a lot of electric so that the battery can work
cold temperature can't "flow" into a warmer object, in this case, the person's hand. the heat energy of the hand gets transferred to the colder object, the ice.
