Answer:
122241.02 J
Explanation:
Work Done = 230000 J



∴Heat exhausted into the air to produce 230,000 J of work is 122241.02 Joule
Plates<span> at our planet's surface </span>move<span> because of the intense heat in the </span>Earth's<span> core that </span>causes<span> molten rock in the mantle layer to </span>move<span>.</span>
Our values can be defined like this,



The problem can be solved for part A, through the Work Theorem that says the following,

Where
KE = Kinetic energy,
Given things like that and replacing we have that the work is given by
W = Fd
and kinetic energy by

So,

Clearing F,

Replacing the values


B) The work done by the wall is zero since there was no displacement of the wall, that is d = 0.
Assuming that the angle is the same for both ropes, then D. is the answer. You have to consider also if the ropes are close together or far apart and if the force to move the object is in line with the ropes or perpendicular to them.
