Determine the magnitude of the magnetic field
A charge moves at a speed of 4.5 * 10^-6m/s in a direction perpendicular to a uniform magnetic field, and the proton moves in a circle of radius 0.20m. Determine the magnitude of the magnetic field.

At time t=0 a grinding wheel has an angular velocity of 30.0 . It has a constant angular acceleration of 35.0 until a circuit breaker trips at time t = 2.50 . From then on, the wheel turns through an angle of 438 as it coasts to a stop at constant
A uniform disk turns at 3.4 rev/s around a frictionless spindle. A nonrotating rod, of the same mass as the disk and length equal to the disk's diameter, is dropped onto the freely spinning disk. They then turn together around the spindle with the
if a lamp has a resistance of 136 when it opreates at a power of 1.00 x 10^2 W, what is the potential difference across the lamp?
a proton accelerates from rest in a uniform electric field of 660 N/C. at one later moment, its speed is 1.60 Mm/s (nonrelativistic because v is much less than the speed of light).
A charge moves at a speed of 4.5 * 10^-6m/s in a direction perpendicular to a uniform magnetic field, and the proton moves in a circle of radius 0.20m.
A block of mass 0.560 kg is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x.
An FM radio station emits an electromagnetic wave which is received by a circuit containing a 3.33 ´ 10-7 H inductor and a variable capacitor set at 7.31 ´ 10-12 F. What is the frequency of the radio wave?
When a different particle with an electric charge of +3.10 x 10-12 C enters the velocity selector traveling east, the net force (due to the electric and magnetic fields) acting on it is 2.22 x 10-9 N, pointing directly upward. What is the speed of
