Region between the poles of a large electromagnet
A straight vertical wire carries a current of 1.60A {rm A} downward in a region between the poles of a large electromagnet where the field strength is 0.565T {rm T} and is horizontal.

A certain string on a piano is tuned to produce middle C (f = 261.63 Hz) by carefully adjusting the tension is the string. For a fixed wavelength, what is the frequency when this tension is doubled?
Calculate the tension in a horizontal string that whirls a 1.6-kg {rm kg} toy in a circle of radius 2.0m m when it moves at 3.0m/s m/s on an icy surface
A 2.50m -long, 500g rope pulls a 7.00kg block of ice across a horizontal, frictionless surface. The block accelerates at 2.30m/s2 . How much force pulls forward on (a) the ice, (b) the rope?
It starts at the bottom with initial speed 9.15 m/s, travels up the incline, stops, and slides back to the bottom at final speed 6.90 m/s. Using energy considerations, find: a) the energy used to overcome friction traveling up and down the incline.
The coefficient of static friction between the cubes is 0.71. What is the smallest magnitude that vector P can have in order to keep the small cube from sliding downward?
When you have traveled only half the distance in part (a), is your speed equal to, greater than, or less than 5.9 m/s? Support your answer with a calculation
Calculate the impulse delivered to the ball during impact. If the ball is in contact with the slab for a time of 1.60ms , find the average force on the ball during impact.
