Light enter the container of the liquid at the angle 37° to the normal refraction beam makes an angle of 27° with the normal. Ca
Sliva [168]

Answer: 1.33

Explanation:

We would apply Snell's law which is expressed as

niSinθi = nrSinθr

where

θi = angle of incidence

θr = angle of refraction

ni = index of refraction of the incident medium(air)

nr = index of refraction of the refractive medium(liquid in this case)

From the information given,

ni = 1(index for air)

θi = 37

θr = 27

By substituting these values into the formula, we have

1 * sin37 = nr * sin27

nr = sin37/sin27

nr = 1.33

The index of the liquid is 1.33

<h3>What is Newton's Second Law of Motion?</h3>

Newton's second law provides a precise explanation of the modifications that a force can make to a body's motion. According to this, a body's momentum changes at a rate that is equal to the force acting on it over time in both magnitude and direction. A body's momentum is equal to the sum of its mass and velocity. Similar to velocity, momentum has both a magnitude and a direction, making it a vector quantity.

acceleration - rate of change of velocity with time, both in terms of speed and direction. A point or object going straight forward is accelerated when it accelerates or decelerates.

There are three types of accelerated motions :

  • uniform acceleration,
  • non-uniform acceleration
  • average acceleration.

express all the units in their most basic form.

kg, newton = kg*m/s², acceleration =m/s²

\frac{ 30000 kg*m/s^{2} }{ 2000 kg}  = 15m/s^{2}
