Question

.
The density of Oxygen at 27°C and normal pressure, is 1.44gm/lit. Calculate the rm.s. velocity of its gas
molecules at 327C.

Draw a graph of P.E, K.E and T.E of a body performing simple harmonic motion.
At what distance from the mean position will the K.E of a body be half its P.E.

Describe different modes of vibrations of a string and hence derive the equations of frequencies of
different modes.


1.) A SHPW is travelling along negative direction of X axis with a speed of 300m/s. If the
amplitude of oscillation is 5cm, and the frequency of oscillation of the particle is 300Hz.
then write the equation of the wave.
2.) Write the equation of velocity of the particle in the above problem.

Answer 1

Answer:

An acceleration can cause speed to increase, decrease, and even stay the same! Acceleration tells you the rate at which the velocity is changing. ... The acceleration can change the magnitude and/or the direction of the velocity. Speed is only the magnitude of the velocity.
