A small rubber wheel is used to drive a large pottery wheel, and they are mounted so that their circular edges touch. The small wheel has a radius of 2.5cm and accelerates at the rate of 7.0rad/s2, and it is in contact with the pottery wheel (radius 22.0cm ) without slipping.
Part A Calculate the angular acceleration of the pottery wheel.
Part B Calculate the time it takes the pottery wheel to reach its required speed of 59rpm.
How many electrons are transferred. What is the smallest thickness of a soap film that would appear black if illuminated with 490 light? imagine there is air on both sides of the soap film.
On a cool morning, when the temperature is 14.0 ^circC, you measure pressure in your car tires to be 20.0 psi. After driving 40.0 mi on the freeway, the temperature of your tires is 50.0 ^circC.
What is the wavelength of emitted photon of the previous question if k = 10eV/ °A2, where °A denotes Angstrom and eV: electron volt. Is the emitted photon in visible spectrum of a human eye.

A 23.00 kg chair initially at rest on a horizontal floor requires a 364N horizontal force to set it in motion. Once the chair is in motion, a 328N horizontal force keeps it moving at a constant velocity. A 23.00 kg chair initially at rest on a horizo..
Now a peg is placed 4/5 of the way down pendulum's path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting po..
