Part A: Multiple Choice
1)A toy for firing a ball vertically conststs of a vertical spring which is compressed by 0.10m. A force of 10.0N is needed to hold the spring at that compression. If a ball of mass 0.050kg is placed on the compressed spring and the spring is released, the ball will reach a height(above its initial position) of:
- 1.0m
- 1.2m
- 1.4m
- 1.6m
2)A rescue plane is flying horizontally with a speed of 30m/s and at an altitude of 125m above the sea when it drops a warning flare. Neglecting air resistance and assuming that the plane does not change its course, speed, or altitude, how far from the plane is the flare when it hits the water?
- 146m
- 195m
- 125m
- 150m
3)A loudspeaker is placed over the open end of a pipe. By changing the frequency of the sound from the speaker, it is found that the pipe has resonances at 700Hz and 900Hz but not 800Hz. This means that:
- The pipe is closed at one end and the fundamental is 100Hz
- The pipe is closed at one end and the fundamental is 200Hz
- The pipe is open at both end and the fundamental is 100Hz
- The pipe is open at both end and the fundamental is 200Hz
4)In a television tube, electrons are accelerated from rest through a potential difference of 1600V. What is the speed of the electrons after this acceleration?
- 16000km/s
- 20000km/s
- 24000km/s
- 28000km/s
5)The electron-volt is a measure of
- charge
- current
- electric field strength
- energy
