A circular cylinder of height 1.20 m having faces of diameter 0.620 m is immersed in water of density 1.00 × 10^3 kg/m3 with its axis vertical so that its faces are parallel to the surface of the water. The upper face is 2.50 m below the surface of the water. The net force on this cylinder is observed to be 1120 N downward. Atmospheric pressure is 1.01 × 10^5 Pa. What is the weight of the cylinder?

A) 7.40 × 10^3 N
B) 1.09 × 10^4 N
C) 3.79 × 10^4 N
D) 4.14 × 10^4 N
E) 1.37 × 10^5 N


Answer: D) 4.14 × 10^4 N

How do the tides slow the rotation of Earth?

A. Tidal bulges move mass away from the center of Earth, slowing its rotation like a figure skater. B. The tip in the Moon's orbital plane makes moving the tidal bulges away from the equator more difficult. C. Alternating high and low tides create a wobble in Earth's rotation. D. Tidal bulges generate drag forces between Earth and its water, slowing its rotation.
