Rule out or accept the following formula for displacement y of particle undergoing periodic motion on the basis of dimentional arguments : (i) a sin 2pi t"/"T (ii) a cos vt (iii) a sin (omegat -kx) where a= maximum displacement of the particle T= time period of motion, t= time interval, v= speed of particle, omega = Angular speed of particle, k= displacement constant.

The SI unit of energy is J = kg m^2 s^(-2), that of speed upsilon is ms^(-1) and of acceleration a is ms^(-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 upsilon^3 (b) K = (1)/(2)m upsilon^2 (c ) K= ma (d) K =(3)/(16)m upsilon^2 (e ) K = (1)/(2) m upsilon^2 +ma

Kinetic theory of gases is a generalization offered by Maxwell. Boltzmann, Clausius, etc. to explain the behaviour of ideal gases. This theory assumes that ideal gas molecules neither attract nor repel each other. Average kinetic energy of gas molecules is directly proportional to the absolute temperature. A gas equation called kinetic gas equation was derived on the basis of kinetic theory PV = (1)/(3) mv^(2) The kinetic energy of 2.8 g of nitogen gas at 127^(@)C is nearly :
