Through a time interval of exactly one period of vibration of a tuning fork, the emitted sound travels a distance:
1) Equal to the length of the tuning fork
2) Equal to twice the length of the tuning fork
3) Of about 330 m
4) Which decreases with time
5) Of one wavelength in air
A 20 g bullet moving at 1000 m/s is fired through a one-kg block of wood emerging at a speed of 200 m/s. What is the change in the kinetic energy of the bullet-block system as a result of the collision assuming the block is free to move?
Light in vacuum is incident on the surface of a slab of transparent material. In the vacuum the beam makes an angle of 27.2° by the normal to the surface, while in the slab it makes an angle of 17.2° with the normal. What is the index of refraction o..
