Q. An air-track glider is attached to a spring. The glider is pulled to the right and released from rest at. It then oscillates with a period of 1.5 and a maximum speed of 32 .
What is the amplitude of the oscillation?
What is the glider's position at = 30 ?
A 2.20 sound wave travels through a pregnant woman's abdomen and is reflected from the fetal heart wall of her unborn baby. The heart wall is moving toward sound receiver as heart beats. The reflected sound is after that mixed with the transmitted so..
A mass of 1.60 kg stretches a vertical spring 0.335 m. If the spring is stretched an additional 0.164 m and released, how long does it take to reach the (new) equilibrium position again.
A grindstone of radius 4 m is initially spinning with an angular speed of 8 rad/s. The angular speed is then increased to 10 rad/s over the next 4 seconds. Imagine that the angular acceleration is constant.
Assume that a binary star system consists of two stars of equal mass. They are observed to be separated by 310 million kilometres and take 4.0 Earth years to orbit about the point midway between them.
As olenoid with 600 turns has a radius of .04 m and is 40cm long. If this solenoid carries a current of 12 A. what is the magnitude of the magnetic field at the center of solenoid.
A ball is held on an incline at the height of 72 cm. it is then released so that the ball rolls down the incline. At the bottom of the incline there is a loop where the ball rolls around in. If the loop is 62 cm high at its highest point what is the ..
