Transcribed Image Text: Consider a place where the gravity is 4 times the gravity on Earth (g’ 4g), then
the frequency of oscillation of a simple pendulum in that place, f’, as compared
to its frequency on earth is:
O f= 9f
O f = f/2
O f = 4f
O f’ = 2f
f’ = f/3
In an oscillatory motion of a simple pendulum, the ratio of the maximum angular
acceleration, e”max, to the maximum angular velocity, e’max, is t s^(-1). What is
the time needed for the pendulum to complete two oscillations?

hp Transcribed Image Text: The wavefunction of a mechanical wave on a string is described by: y(x,t) =
0.012cos(Tx-100rt-2Tt/3), where x and y are in meters and t is in seconds. The
transverse velocity of an element on the string at the left end (x = 0), at time t = 0
is:
O +0.6v3n m/s
+0.6n m/s
O None of the listed
-0.6n m/s
O -0.613n m/s
A block of mass m = 5 Kg is attached to a spring of spring constant k. The block
oscilliates in simple harmonic motion on a frictionless horizontal surface. The
block-spring total mechanical energy is 14.4 J. The maximum velocity of block.
vmax, is:
3 m/s
3.8 m/s
2.1 m/s
18 m/s
