A bar of length l is clamped at x=0 and loaded with a mass mat x=l.(a) apply these boundary conditions to equation x=A e^(wt+kx)+Be^(wt- kx) and thereby determine an equation from which the fundamental frequency of longitudinal vibrations may be computed.(b) Determine the fundamental frequency of such a system composed of a steel bar of0.5-mlength and 0.0001 m2 cross-sectional area to which is fastened a mass of 0.15 kg.(c) When a bar in vibrating in this manner, what position along tghe bar haste maximum longitudinal displacement amplitude?
The index of refraction of a particular medium is nearly the same for all wavelengths hence we often associate a single value the average value of the index of refraction to the me
A coil of inductance 318.3mH and negligible resistance is linked in series with a 200 resistor to a 240V, 50Hz supply. Calculate (a) The inductive reactance of the coil,
The length of a simple pendulum is about 100cm known to have a accuracy of 1mm.Its period of oscillation is 2s determined by measuring the time for 100oscillations using a clock of

Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
What do you mean by Doppler effect? Derive a mathematical expression for the apparent frequency of a note, when source of sound and observer are approaching each other.
composiotion of two simple harmonic motions ai right angles to each other nd having time period in the ratio 1:2
CELL EMF: The size of a cell has no bearing on the emf that it will produce, the generated emf being determined solely by the materials used in its construction. Another point
