Question
What are the two basic characteristics of a simple harmonic motion?

Answer

The two basic characteristics of a simple harmonic motion:
  1. Acceleration is directly proportional to displacement.
  2. The direction of acceleration is always towards the mean position, that is opposite to displacement.

A manometer reads the pressure of a gas in an enclosure as shown in Fig.(a) When a pump removes some of the gas, the manometer reads as in Fig. (b) The liquid used in the manometers is mercury and the atmospheric pressure is 76cm of mercury.
Give the absolute and gauge pressure of the gas in the enclosure for cases (i) and (ii) in units of cm of mercury.
How would the levels change in case (i) if 13.6cm of water (immiscible with mercury) are poured into the right limb of the manometer? (Ignore the small change in volume of the gas.)

The SI unit of energy is $J = kg m ^2 s ^{-2}$; that of speed $v$ is $m s ^{-1}$ and of acceleration $a$ is $m s ^{-2}$. Which of the formulae for kinetic energy ( $K$ ) given below can you rule out on the basis of dimensional arguments ( $m$ stands for the mass of the body) :
(a) $K=m^2 v^3$
(b) $K=(1 / 2) m v^2$
(c) $K=m a$
(d) $K=(3 / 16) mv ^2$
(e) $K=(1 / 2) m v^2+m a$
