A horizontal disk with a radius of 0.10 m rotates about a vertical axis through its center. The disk starts from rest at t = 0, and has a constant angular acceleration of 2.1 rad/s )
At what value of t will the radial and tangential components of the linear acceleration of a point on the rim of the disk be equal in magnitude?

What do radio waves and microwaves have in common? both are at the side of the spectrum that has the shortest wavelengths. both are at the side of the spectrum that has the lowest radiant energy. both are at the side of the spectrum that has the lowest frequency. both are found next to visible light on the electromagnetic spectrum.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.
