A motor run by a 9.5-V battery has a 20-turn square coil with sides of length 4.8 cm and total resistance 21 Ω . When spinning, the magnetic field felt by the wire in the coil is 0.021 T .

The period of a pendulum is the time required for it to make one complete swing back and forth. The formula of the period P of a pendulum is P = 2(pi) times the square root of l over 32, where l is...

You slide a block with a mass of m down an incline plane with a height of h that has a length of L. If there is a kinetic friction f acting on the object as it slides down the incline then...

What is the change in internal energy, how much work is done by the gas, and how much heat flowed into or out of the gas.

We would like to test the relation T= 2π* sqrt (L/g) for a pendulum at small angle oscillation in our lab. How can we set it up? We have ropes and masses and stop watches. 1) What would you...

In general a rough rule of thumb is to say that the speed of car in the city is two times the speed of biking in the city and biking is about 3 times faster than walking. If the average speed of walking...

Question: As the speed of a bicycle moving along a level horizontal surface changes from 2 m/s to 4 m/s, the magnitude of the bicycle's: Multiple Choice: a. total energy remains...

During the Grammy awards, Pink stunned the audience with some acrobatics. She was hoisted about 20m above stage with silk ropes ( all the while she was singing ). How much potential energy did she...
