It is said that Galileo discovered a basic principle of the pendulum - that the period is independent of the amplitude - by using his pulse to time the period of swinging lamps in the cathedral as they swayed in the breeze. Suppose that one oscillation of a swinging lamp takes 5.4s.
a-) How long is the lamp chain?
b-) What maximum speed does the lamp have if its maximum angle from vertical is:
Two small charges with a mass of 1.0 g each are connected by 2.0-cm-long insulating rod of negligible mass. What is the dipole moment of the rod?
A flywheel with a diameter of 0.877 m is rotating at an angular speed of 146 rev/min. What is the angular speed of the flywheel in radians per second
How much time does the object take to reach the ground.
A 3.80-kg cylindrical rod of length 2.00 m is suspended from a horizontal bar so it is free to swing about that end. What is the angular velocity of the rod immediately after the collision
A uniform 1.80m ladder of mass 6.30kg is leaning against a vertical wall while making an angle of 53.0%u2218 with the floor. How much work did this person do against gravity
A motorcycle and a police car are moving toward one another. The police car emits sound with a frequency of 532 and has a speed of 25.5. The motorcycle has a speed of 12.50. What frequency does the motorcyclist hear in this case?
A jumper in the long-jump goes into the jump with a speed of 12 m/s at an angle of 20 deg. above the horizontal. How far does the jumper jump?
A disk of radius R and unifrom surface charge density sigma spins with angular velocity Omega about the y-axis. Find its magnetic dipole moment.
