Answer:
It depends on the mass of each of the bodies, and the distance that separates them.
Explanation:
The force of attraction between two objects depends on the mass of each of the bodies as well as the distance that separates them. This force can be easily calculated by means of the universal gravitation law formulated by Newton.
Next, we will see the equation that explains the law of universal gravitation.
Answer:
W = 2352 J
Explanation:
Given that:
- mass of the bucket, M = 10 kg
- velocity of pulling the bucket, v = 3
- height of the platform, h = 30 m
- rate of loss of water-mass, m =
Here, according to the given situation the bucket moves at the rate,
The mass varies with the time as,
Consider the time interval between t and t + ∆t. During this time the bucket moves a distance
∆x = 3∆t meters
So, during this interval change in work done,
∆W = m.g∆x
