A power boat of mass 500 kg is cruising at a constant speed of 8.9 m/s. The propeller provides a drive force of 765 N. The driver of the boat shuts off the engine, and the boat coasts to a halt. Assume -- contrary to fact -- that the resistive force due to the water is constant, independent of the boat's speed.
(a) How far does the boat coast? (b) How much time does it take for the boat to come to rest after the engine is turned off?

A concentric tube heat exchanger is comprised of a thin wall inner tube of 25.4 mm diameter and an outer tube of 47 mm diameter. The heat exchanger is used for cooling lubricating
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
Centrifugal pseudoforce A pseudoforce which occurs while one is moving in consistent circular motion. One feels a "force" directed outward from the center of motion.
Curie constant; C (P. Curie) A characteristic constant, based on the material into question, which denoted the proportionality among its susceptibility and its thermodynamic te
