M1 v1 = (m1 + m2)v2.
All of the exponents should be lowered to the bottom right of the letters.
Positive will react better together. But opposites will try to get as far away as possible.
Answer:
Option D
Explanation:
The work done can be given by the mechanical energy used to do work, i.e., Kinetic energy and potential energy provided to do the work.
In all the cases, except option D, the energy provided to do the useful work is not zero and hence work done is not zero.
In option D, the box is being pulled with constant velocity, making the acceleration zero and thus Kinetic energy of the system is zero. Hence work done in this case is zero.
Answer:
Discrimination
Explanation:
As a society, there are people who treat men different from women. Back in time, men got paid more. Men were more likely to get a job.
