Awheel 1.90 m in diameter lies in a vertical plane and rotates about its central axis with a constant angular acceleration of 4.40 rad/s2. the wheel starts at rest at t = 0, and the radius vector of a certain point p on the rim makes an angle of 57.3° with the horizontal at this time. at t = 2.00 s, find the following. (a) the angular speed of the wheel

Ineed with these 2 questions. you.

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

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