A track is mounted on a large wheel that is free to turn with negligible friction about a vertical axis. A toy train of mass m = 0.150 kg is placed on the track and, with the system initially at rest, the train's electrical power is turned on. The train reaches a steady speed 0.14 m/s with respect to the track. What is the angular speed of the wheel if its mass is 1.4m and its radius is 0.40 m? (Treat the wheel as a hoop, and neglect the mass of the spokes and hub.) Answer in (rad/s).
For the two conducting balls as described in problem 1, when one ball is attached to a torsion balance the wire is twisted by a torsional angle of 1°. find the torsion constant of the wire
A Cepheid variable has been found to have a period of 22 days, from this its luminosity is determined to be 2.8 x 1029 W, calculate the distance to the Cepheid
What is the potential difference in volts between the plates.
If the ball is free from rest at a height of 0.67 above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? Suppose the ball is a solid sphere of radius 2.2 and mass 0.14.
The load-bearing piston in a certain hydraulic system has an area 49 times as large as the input piston. how large a force must be applied to the input piston
A 3.3kg block sits on a table. A 3.0kg bullet is fired horzontally at a speed of 520 m/s, find the speed of the block immediatley after the bullet exits
Calculate the magnitude of the electric field at one corner of a square 1.43
Blocks with masses of 2.0 kg , 3kg , and 6.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 53 N force applied to the 2kg block.
