Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them
Explanation:
heat engine is correct answer
Answer:
Explanation:
Given
mass of ship =1240 kg
height=37 m
(a)Work done by Tension in cable+work done by gravity =0
Work done by gravity =change in potential energy of mass
Thus work done by tension=449.624 kJ
(b)work done by force of gravity
=-449.624 kJ
