Aclosed cylindrical tank that is 8 ft in diameter and 24 ft long is completely filled with gasoline. the tank, with its long axis horizontal, is pulled by a truck along a horizontal surface. determine the pressure difference between the ends (along the long axis of the tank) when the truck undergoes an acceleration of 5 ft/s2

Hey.. ♥️♥️ me in solving this question

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
