The total energy of a particle, executing simple harmonic motion isAns) In simple harmonic motion when a particle is displaced to a position from its mean position, then its kinetic energy gets converted into potential energy and vice-versa. Therefore, total energy of a particle remains constant or the total energy in simple harmonic motion does not depend on displacement x.
Two stable isotopes of lithium and have respective abundances of 7.5% and 92.5%. These isotopes have masses 6.01512 u and 7.01600 u, respectively. Find the atomic mass of lithium.
Determine the change in entropy, in joules, when 5 moles of an ideal gas expands from a value of 4 lits. to 40 lits. at 27°C. (R = 8.314 JK -1 mol -1 )
Translational : If a body goes such that its orientation does not change with respect to time then body is said to move in translational motion. ROTATION : If an object is rota

Is a godd illuminator is bigger better? This is somehow surprising that manufacturers place huge emphasis in the power consumption, stating with a machine is 50, 100 or 400 Wat
Q. A capacitor blocks d.c. but allows a.c. Why? Capacitive reactance XC = 1/ω C = 1 / 2πν C Where ν is the frequency of the a.c. supply. In a d.c. circuit
Displacement related with a wave is given by y (x, t) = 0.1 cos(0.2x-2t). Where x y are in cm and ‘t' in second. Determine the wavelength, amplitude, frequency and velocity.
the velocity of a particle moving along x axis is defined by v=kx^3-4x^2+6x where v is in m/s,x in m and k is a constant .if k=2 compute the acceleration when x=2m
