Answer:
jumping, pulling a elastic band, bouncing a ball
Explanation:
when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
When we pull an elastic band, it automatically returns to its original position. The more you pull the more force it generates. This is the same when you pull or compress a spring. The action (applied force) is stored as energy and is released as a reaction with an equal and opposite force
A ball is able to bounce because of the reaction from the ground. If there was no reaction then the ball would not bounce but rather stick to the ground.
When air is blown above the surface of liquid, it will take away the liquid carrying air particles from the air above the liquid, resulting in decrease in humidity and increase in rate of evaporation.

Answer:
7572 m/s
Explanation:
The force between two masses separated by a distance r is given as:
Where F is the attractive force between 2 masses, m1 and m2, r is the distance between the centres of the masses and G is the universal gravitation constant, which is 
The mass of the earth (
) is far greater than the mass of the sputnik (
). Therefore 
. The mass of the sputnik is neglected, therefore:
But F is actually centripetal acceleration, a = v²/r
Condensing because when particles vibrate they condense.
Explanation:
Because it's a power to turn the wheels of industry
