A particle executes simple harmonic motion between $x = -A$ and $x = +A$. If time taken by particle to go from $x = 0$ to $\dfrac{A}{2}$ is $2$s, then time taken by particle in going from $x = \dfrac{A}{2}$ to A is

There is a body having mass $m$ and performing SHM with amplitude '$a$'. There is a restoring force $F=-Kx$, where $x$ is the displacement. The total energy of the body depends upon which of the following?

What is the effect of humidity on sound waves when humidity increases?

A tuning fork of frequency $n$ produces $x$ beats per second when sounded with a vibrating sonometer string. What must have been the frequency of the string, when a slight increase in tension produces lesser beats per second than before?
