We are given with
n1 = 1.33
n2 = 1.6
x = 8.3x10-5 cm
The angle of incident is normal, angle is 90
Using Snell's law
sin θ1 / sin θ2 = n2 / n1
Substitute the given values and solve for θ2<span />

Explanation:
Answer:
2 a) it is less dense than the water
2 b) it is more dense than the water
3 a ping pong ball is hollow and less dense than the water so it quickly bounces up to the surface of the water

Answer: Machanical advantage of the machine is 1.86
Explanation: Machanical advantage of a machine is the ratio of the Force to overcome which is the load in this case 24kg * 10= 240N to the force exerted(Effort) to overcome the load in this case 129N.
So, we have
MA = load/effort
= 240N/129N
= 1.86.
