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?
What is the Ohm Law? Ohm discovered that the amount of current was directly proportional to the voltage (more voltage gives more current) and inversely proportional to the resi

At 200.0 K, silicon has 3.79 x 10 -18 free electrons per atom. How many free electrons/cm 3 are there in silicon at this temperature?
Motion of an object in a straight line is called one dimensional motion. The location of a particle in one dimensional motion can be explained by only one variable (say x). For a p
