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
The answer is the third one. Maglev is short for Magnetic Levitation in which trains skim on a guideway utilizing the guideline of attractive shock. Every magnet has two shafts. Presently in the event that you play with two magnets, you'll understand that inverse shafts pull in, though comparable posts repulse. This shocking property of magnets is utilized as a part of Maglev trains. However,instead of utilizing lasting magnets, the standard of electromagnetism is utilized to make solid and huge impermanent magnets. At the point when an electric current is gone through a loop of wire, attractive field is created around the curl as indicated by Faraday's laws.
