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
- time taken, t = 10 min
- 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

Answer:
C. The spring constant of spring 2 is larger than spring 1.
Explanation:
As we know that spring constant also called the stiffness constant of a spring is the value of force required for the deformation of the spring by a unit length.
Mathematically given as:
where:
stiffness constant
force on the spring
change in length of the spring
It is given in the question that spring 1 is easily compressible and requires less force to compress as compared to spring 2 and hence it has lesser stiffness constant than that of spring 2.
