Jessica's kettle is old and a bit temperamental. She decided to buy a new smarter plastic kettle. On starting the wire Jessica noticed that her new kettle has only two wires . The wire that would be connected to a pin named A was missing. I. Give the possible name of the pin A?
ii. What is the purpose of the wire attacked to pin A.
iii. Explain why this wire is not necessary for her new kettle.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )
