A straight wire lies along the y-axis initially carrying a current of 10 A in the positive y-direction. The current decreases an
d reverses to 10 A in the negative y-direction, the change in current happening at a uniform rate. In the 1st quadrant a square conducting coil has 2 sides parallel to the y-axis and the other 2 sides parallel to the x-axis. The side of the coil nearest and parallel to the straight wire is at a distance equal to the length of one of the sides of the square. As the current is going from 10 A in one direction to 10 A in the other, in which direction is the induced current in this side of the square coil nearest to the straight wire

Answer:
The the coefficient of kinetic friction between the horizontal surface and the block is 0.536.
Explanation:
Given that,
Spring constant = 105 N/m
Mass of block = 2.00 kg
Compress = 0.100 m
Distance = 0.250 m
We need to calculate the coefficient of kinetic friction
Using relation between friction force and restoring force
Put the value into the relation
Hence, The the coefficient of kinetic friction between the horizontal surface and the block is 0.536.
