Answer:
9727160J
Explanation:
Given parameters:
Height of elevator rise = 436m
Force exerted = 22310N
Unknown:
Work done by the elevator lifting mechanism = ?
Solution:
The work done by a body is the force applied to move a body in a specific direction;
Work done = force x distance moved
In this case, the force and distance moved is provided already;
Work done = 22310 x 436 = 9727160J
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

Alpha radiation consists of fast-moving helium particles, and Beta radiation consists of electrons. Although helium particles are tiny, and electrons even tinier, these still consistent matter. Alpha and Beta waves consist of matter.
Gamma radiation consists of pure energy in the form of electromagnetic rays, and therefore do not consist of matter.
The answer is A) It does not consist of matter
