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?
Determine the HVL of photons in air, water, muscle, bone, and Pb for energies of 5 keV, 100 keV, 1 Mev and 100 MeV and then fill in the table below. Note that you must find the HVL

A sinusoidal voltage trace displayed by an oscilloscope is shown in Figure. If the 'time/cm' switch is on 500µs/cm and the 'volts/cm' switch is on 5V/cm, find, for the waveform,
A boy goes to market with a average speed of 29 km/h.He returns back half the way he went with a average speed of 40 km/h.Find average speed for whole journey.
why specific heat is different at different temperature?
Q. What do you mean by additive nature of charges? Give an example. Additive nature of charge The entire electric charge of a system is equal to the algebraic sum of electric
When you think of magnetic materials, you possibly think of nickel, iron or magnetite. Distinct to paramagnetic materials, the atomic moments in these materials show very strong in
What is dispersion? Dispersion within optics consider as the change in phase velocity of an electromagnetic wave along with wavelength. Conversely, when there is a variation o
