Vedmedyk [2.9K]
The relation between the angle of incidence and the angle of refraction is known as Snell's Law. Since the light travels with different speed in different media, the direction of the ray of light will change when it crosses the boundary between the two media

two forces equal in magnitude and opposite in direction act at the same point on an object. is it possible for there to be a net
elena55 [62]

If the forces are equal, at a distance equidistant it is not possible to act a pair on the body since both torques cancel each other. Being of the same magnitude and in the opposite direction, the sum of the torques will be zero.

Papessa [141]

Answer:

Emf=24.4V

Explanation:

From the question we are told that:

Angular speed \omega=40*\omega'

Radius r=0.33m

No. Turns N=163

Area A= 3.23 * 10^{-3} m^2

Magnetic field. B=0.0948T

Acceleration a=0.60m/s^2

Time t=6.72s

Generally the equation for momentum is mathematically given by

\omega'=\omega_o+\frac[a}{r}t

\omega'=0+\frac{0.60}{0.33}*6.72

W=12.22rad/s^2

Therefore

\omega=Aw

\omega=12.22*40

\omega=488.7rads/s

Generally the equation for Peak emf is mathematically given by

Emf=NBA \omega

Emf=163*0.0948* 3.23 * 10^{-3} m^2*488.7rads/s

Emf=24.4V

What is a medum and why do waves travel through them?
bearhunter [10]
A medium is a substance or material that carries the wave. Sounds waves need a medium in order to travel through a wave to help it travel as it cannot travel through a vacuum. Mechanical waves need a medium to transport energy.
