The greatest and least magnitude of the resultant of two forces of constant magnitude are P & Q. Proof that when the forces act at an angle of 2 alpha, their resultant is of magnitude.
(P2cos2alpha+Q2sin2alpha)1/2
A plano - convex lens of radius of curvature 2.5 m is placed on an optically plane glass plate in air medium and a parallel beam of monochromatic light is incident normal
Explain about the principle of acousting grating. Acousting Grating Principle: While ultrasonic waves are passed by a liquid, the density of the liquid varies layer by layer
an orchestra tunes up for the big concert by playing an A, WHICH RESOUNDS WITH A FUNDAMENTAL FREQUWNCY OF 440HZ FIND THE SECOND AND TIRD HARMONICS OF THIS NOTE
A bat emits a sound whose frequency is 142 kHz. The speed of sound in air at 20.0°C is 343 m/s. However, the air temperature is 35°C, so the speed of sound is not 343 m/s. Find the
Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength. Work function W = hγ o = h C / λ 0 λ 0 = h C / W = 6.626 X 10 -34 X 3 X 10 8
Can you show mathematically that the total energy of a simple harmonic oscillator remains constant?
