A) A torque of 11Nm is applied to a heavy wheel whose moment of inertia is 34 kgm2. What is the angular acceleration of the wheel?
B) If the wheel was initially at rest and the torque is applied for 25 s, what will be the rotational frequency ? of the wheel at the end of the 25 s?
Two large identical flat metal plates are placed parallel to one another, seperated by a small distance compared to their linear size. One plate is given a charge per unit area 1.80E-5 C/m2 and the other a charge per unit area -1.80E-5 C/m2. Using..
Describe the interference of two wave pulses with different amplitudes if they are a) in phase and b) completely out of phase
Assume air resistance is negligible; from what height (in cm) above the compressed spring was the block dropped.
A 170-turn circular coil has diameter 5.05cm and resistance 1.20? . A magnetic field perpendicular to the coil is changing at 1.20T/s
What is an angular acceleration
When a certain spring is stretched by an amount x, it produces a restoring force of F(x) = ax=bx^2, where a and b are constants. How much work is done through an external force in stretching the spring by an amount D from its equilibrium length.
what is the linear speed of the fishing line. The force exerted by the wind on the sails of a sailboat is 300 N north. The water exerts a force of 150 N east. If the boat (including its crew) has a mass of 300 kg, what are the magnitude and directi..
Neglect air resistance during the descent. She comes to rest 3.00 m under the surface of the water. Identify the average force that the water exerts on the diver. This force is nonconservative.
Scientists plan to release a space probe that will enter the atmosphere of a gaseous planet. The temperature of the gaseous planet varies linearly with the height of the atmosphere.
A particle leaves the origin with an initial velocity of 4.20 m/s in the x direction, and moves with constant acceleration ax = -1.80 m/s2 and ay = 2.30 m/s2. a-How far does the particle move in the x direction before turning around? b-What is the..
A whale swims due east for a distance of 1.5 km, turns around and goes due west for 5.7 km, and finally turns around again and heads 4.5 km due east. (a) What is the total distance traveled by the whale? km (b) What are the magnitude and direction..
The potential at location A is 392 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 780 V, and when released from rest from this spot, the particle arrives at B wit..
