Two balloons with charges of + 3.00uC and - 8.00 uC attract each other with a force of 0.0626 Newton. Determine the separation distance between the two balloons.

Calculate the de broglie wavelength (in picometers) of a hydrogen atom traveling at 425 m/s.

the mechanical advantage of an automobiles wheel and axle is 0.0893 if the wheel is output force is 2220n what is the input force that turns the axle

What is the radius of a communications satellite's orbital path that is in a uniform circular orbit around Earth and has a period of exactly 24.0 hours (86,400 seconds). (Measurement is from the center of Earth.) G = 6.67 * 10-11 N. m2/kg2 ME = 5.

How do you solve this If y=10^; then x=

A 150 g ball is thrown towards a wall with a speed of 6.5 m/s. If bounces off the wall with a speed of 3.5 m/s, determine the impulse provided by the wall.

People have proposed driving motors with the earth's magnetic field. This is possible in principle, but the small field means that unrealistically large currents are needed to produce noticeable torques.

A hot air ballon with a mass of 500kg ascends at a constant rate of 1.5 m/s for 20s. how much work is done by the upward force?

A construction team gives an estimate of three months to repave a large stretch of a very busy road. The government responds that it's too much inconvenience to have this busy road obstructed for three months, so the job must be completed in one

Determine the time needed for the load at b to attain a speed of 10 m/s, starting from rest.

A tea kettle is warmed on an electric stove. After a while, water vapor builds inside the kettle and causes a whistle in the lid to make a sound. How does this demonstrates the first law of thermodynamics?
