The experiment you did in lab is repeated, using a uniform metal bar that is 80.0 cm long instead of the meterstick. since the bar is uniform, its center of gravity is at its center. the new experiment uses different hooks for hanging the masses from the bar, with mhook = 5.0 g. as in the experiment you did in lab, x1 = 5.00 cm, m1 = 300.0 g, and xp = 25.0 cm. in the new experiment, you make the same measurements as in your lab and plot x versus 1 m2 + mhook . the line that is the best fit to your data has slope 2800 cm · g. what is the mass of the bar?

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
