Divers often inflate heavy duty balloons attached to salvage items on the sea floor. If a balloon is filled to a volume of at a pressure of , what is the volume of the balloon when it reaches the surface

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?
