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.
Answer:
Total Resistance = 20 ohms
Explanation:
1/Rt = 1/R1 + 1/R2
1/Rt = 1/40 + 1/40
1/Rt = 1/20
Rt = 20

4.5 Joules. I think it'd be 4.41, but when you round it, it's 4.5.

Natural sources of light include our sun and other stars, where the source of energy is nuclear energy (recall that the moon does not produce light but merely reflects sunlight), lightning, where the source is electrical, and fire, where the energy source is chemical.
