Trucks can be run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 689 rad/s. one such flywheel is a solid, uniform cylinder with a mass of 507 kg and a radius of 1.2 m that rotates about its central axis. what is the kinetic energy of the flywheel after charging

Which of the following is not a part of a wave? question 2 options: a: frequency b: refraction c: wavelength d: amplitude (whoever answers correctly first gets brainiest! ) ~kayla

Write down two additional questions about earth's magnetic field that will make your presentation more informative.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
