The diagram to show whether an object under water would seem deeper or closer to the surface than it actually is supposing that

Answer to Problem 22R
The motion of boat will be up and down and boat will not move forward.
Explanation of Solution
Introduction:
The speed of light depends on the refractive index. Higher the refractive index lower will be the speed.
As it is directed in the question that the speed of light is greater in water than the speed in air, this shows that for this problem the refractive index of water is less than the refractive index of air. If the speed is faster in air then the object under water will look deeper as it will go away from the normal.
The diagram is shown below.
Figure-(1)
The refracted ray bend away of normal so the object will look deeper than actually it is.
Conclusion:
The diagram is shown in Figure-(1) and the object will look deeper.

- Please help with calculating the impusle, thanks! Having calculated the impact and rebound velocities of the ping pong ball and the tennis ball calculate the rebounding impulse: 1.Measure the weight of the balls and determine their mass. Tennis ball: 0.57 kg Ping Pong Ball: 0.00246 kg The impulse, I, is equal to the change in momentum, Pf-Pi. Note the sign change, i.e., going down is negative and up is positive. The unit for momentum is kg-m/s. The change is momentum, impulse, is often givens the equivalent unit of N-S, Newton-Secondarrow_forward5. Three blocks, each with mass m, are connected by strings and are pulled to the right along the surface of a frictionless table with a constant force of magnitude F. The tensions in the strings connecting the masses are T1 and T2 as shown. m T1 T2 F m m How does the magnitude of tension T₁ compare to F?

- A ping pong ball and a tennis ball are dropped and there is a very small gap between them when the tennis ball hits the floor. Indicate the directions of the momentums of the ping pong ball and the tennis ball after the tennis ball collides with the floor, but before the balls collide with each other.
