Q: Graph R shows the variation of amplitude of an oscillating system with the frequency at which it is driven. When the damping of the system is decreased, graph S is obtained. Which of the following best shows the graph S?
A: C

Q: A spring-mass system, with a 10 g mass, is performing simple harmonic motion with a period of 4 s and amplitude of 2 cm. Which one of the following graphs shows a possible energy graph?
A: B?

Q: Due to damping, the amplitude of a system oscillating in simple harmonic motion decays exponentially with time. The total energy
A: varies linearly with the square of the amplitude of the oscillation.???

YF! SHAUN IS THE MAN!
