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.
Q. While rummaging in her backpack for her cell phone, Sally's Mini-Cooper rear ends Joey's Suburban. Sally's car is totaled while the suburban is fine. If Sally's car hit the sub
When a driver brakes an automobile, the friction between the brake drums and the brake shoes converts the car's kinetic energy to thermal energy. If a 1450 kg automobile traveling

#questi1. A sound with a frequency of 261.6 Hz travels through water at a speed of 1435 m/s. What is the wavelength of the wave? a. 1.83 x 10 -1 m b. 3.753 x 10 5 m c. 5.486 m
Capacitors in parallel: Three capacitors are connected in parallel. If on closing the switch S a current I flows in the circuit, then from Kirchoff's first law:
Define isothermal process For isothermal process temperature remains constant i.e. Δu = 0. Thus according to first law of thermodynamics ΔQ =Δw Heat supplied to the syste
Q. Why X-rays are not used in microscopes? 1) The wavelength of X-rays is slighter than that of the visible light. 2) X-rays can't be focussed as visible radiations are foc
