Running water moves the air next to it. Moving air has less pressure than air that is still. This is the Bernoulli principle, and helps airplanes to fly. With less pressure on one side from moving air, and more pressure on the other side from still air, the ping-pong ball moves towards the water.

yes because the ball is pulled to the ground while the ball is in mid-air because of gravity
The ball follows a parabolic path when thrown. In a vacuum (with no air or other forces acting upon it) the gravitational pull of the earth causes the ball to accelerate toward the earth (9.8m/sec
Put an exact amount of water in a measuring cup. Drop in a golf ball. The increase in water level equals the volume of the golf ball, assuming the ball doesn't float. For example, 200mL before ball. 280ml after ball dropped in. Therefore volume equals 40ml or 40 Cubic Centimeters.
The heat cause the air inside the ball to expand and undent the ball
The diameter was 26 cm.
