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

No, he did not perform any work. Work is when you’re using energy which results in a force. Even though he was tired and sweaty, he did not move the boulder. So therefore he did not perform any work.

RSB [31]

Answer:

Explanation:

Average velocity = Displacement/Time

ΔS = -10+6

ΔS = -4m

Given tme = 30s

Average velocity = -4/30

Average velocity = -0.13m/s

Average speed = Distance/Time

Total distance covered = 10m+6m

Total distance covered = 16m

Average speed = 16/30

Average speed = 0.53m/s
