What is the kinetic energy of a 478 kg object that is moving with the speed of 15 m/s

Several processes form metal ore. match each process to its description. volcanic activity weathering hydrothermal energy rocks break down as they interact with air and water. arrowright density differences and other factors cause metals to concentrate in igneous rocks. arrowright seawater heats up from contact with hot rock, and metals dissolve in it. the water rises and contacts cooler water, causing metal ores to settle on the ocean floor. arrowright

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?
