A pendulum makes 40 vibrations in 20 seconds. Calculate the period?

The gravitational force of attraction between Earth and the Sun is 3.52 x 1022 newtons. Calculate the mass of the Sun. [Show all work, including the equation and substitution with units.]

Determine the magnitude and direction of the force on an electron traveling 3.58 E 6 m/s horizontally to the west in a vertically upward magnetic field of strength 1.30 T.

What is two types of organelles

Two identical strings, A and B, have nearly the samtension. When they both vibrate in their fundamental resonantmodes, ther is a beat of 3Hz. When string B is tightenedslightly, to increase the tension, the beat frequency becomes 6 Hz. This means.

At a race track, a car of mass 1150 kg crashes into a concrete wall at a speed of 85 m/s a. If the car comes to a stop when it hits the wall, what the magnitude of the impulse applied to the car? The car crashed into the wall, stopping in 0.

Which energy transformation takes place when a firecracker explodes

Newton's first law states that an object traveling with a constant velocity will remain traveling at a constant velocity unless an unbalanced force acts.

A karate expert breaks a stack of bricks with his bare hand. If the force applied is 520 newtons and the impact time is 5.0 * 10-4 seconds, what is the value of impulse?
