Question
Please answer the following....
Answer True or False (10 points)
Acceleration of the pendulum has maximum magnitude at the equilibrium point.
True False
Kinetic energy of the pendulum is equal to zero at the turning point.
True False
Linear restoring force increases linearly with the displacement and is has the same sign as the displacement from equilibrium.
True False
Velocity of the sound wave decreases with the temperature.
True False
Light is a longitudinal wave.
True False
When the source of the sound moves away from the observer, frequency of the sound increases.
True False
Intensity of light coming from the Sun on the Mercury is lower than the intensity of light on the Earth.
True False
Superposition between electromagnetic waves can never happen.
True False
Standing sound waves on the open-open end pipe always have nodes of the pressure at the both ends.
True False
X-rays have longer wavelength than the microwaves.
True False
Explanation / Answer
1)Ture
(max velocity at equilibirum position)
2)True
(yes, since PE is maximum there)
3)False
(opposite sign with respect to equilibrium position)
4)False
(velocity of sound increases with temp)
5)True
Yes light is a longitudinal wave.
6)False
(The frequency decreases as the source moves away)
7)True
(since mercury is far and I = P/A)
8)False
9)True
10)False
