A microphone is attached to a spring that is suspended from the ceiling. Directly below on the floor is a stationary 440 Hzsource of sound. The microphone vibrates up and down in simple harmonic motion with a period of 2.0 s. The difference between the maximum and minimum sound frequencies detected by the microphone is 2.1 Hz. Ignoring any reflections of sound in the room and using 343 m/s for the speed of sound, determine the amplitude of the simple harmonic motion
which one of the following engine has thr highest effeciency carnot engine or rankine engine or otto engine?
A 2.1 kg block slides along a horizontal surface with a coefficient of kinetic friction μ k = 0.31. The block has a speed v = 1.4 m/s when it strikes a massless spring head-on.
The points of maximum amplitude are called as antinodes. At ends density and air pressure both are very low.

what is poission''s equation?Establish poisson''s equation for space distribution of charges.discuss its significance.
Q. Describe the isotopes? Answer:- An atom of an element that has a diverse number of neutrons in its nucleus to other atoms of the element.
why CPH has speed Vc and Vc is greater than c? Answer; since you know photon has spin. Thus the path per time of a point on photon is greater than c it means the speed of photo
