Explanation:

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

Friction is the resistance of motion. Which means when resistance applies it makes friction which makes friction force.

NikAS [45]

Answer:

b. 5 N

Explanation:

Each book weighs 5 N. Therefore, five books weigh 25 N. The friction force is:

Ff = Fn μ

Ff = (25 N) (0.2)

Ff = 5 N

A 15-turn circular wire loop with a radius of 3.0 cm is initially in a uniform magnetic field with a strength of 0.5 T. The fiel

miskamm [114]

Answer:

0.212V

Explanation:

The induced emf in circular loop is $\epsilon=-d\frac{\phi_B}{dt}=-NA\frac{dB}{dt}$

N = Number of loops = 15

A = Cross sectional Area = $\pi$ $0.03^{2}$ = 0.0009 $\pi$

dB = change in magnetic Field = 0-0.5 = -0.5

dt = time taken = 0.1sec

$\epsilon=-15*0.0009\pi *\frac{-0.5}{0.1}$ = 0.212V
