Answer:
W= F × d
W= 2kn × 3.6
W= 7.2 J
Work is measured in Joules!
I think it is B because gravity is <span>the field force of mutual attraction between any two masses, especially an object and the earth</span>
The range of force exerted at the end of the rope is 285.7 N to 1,000 N.
<h3>Net horizontal force of the cylinder</h3>
The net horizontal force of the cylinder when it is at equilibrium position is determined by applying Newton's second law of motion.
∑F = 0
F - μFn = 0
F - 0.2(5,000) = 0
F - 1,000 = 0
F = 1,000 N
The strength of the applied force increases as the number of turns of the rope increases.
minimum force = total force/number of turns of rope
minimum force = 1,000/3.5
minimum force = 285.7 N
Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

Answer:
11700j
Explanation:
add the two because the plate has to maintain the temp.
2700+9000=11700
