Derive an expression for the shift in lambda in the peak wavelength of the planck function for a black body temperature T, corresponding to a small shift in temperature.
A simple pendulum has a mass of 0.350 kg and a length of 7.00 m. It is displaced through an angle of 12.0° and then released. Solve this problem by using the simple harmonic motion model for the motion of the pendulum.
suppose you had two objects separated by 1000 meters. one had a mass of 50 kg and the other had a mass of 150 kg. what
A resistor (R = 900 ?), a capacitor (C = 0.25 µF), and an inductor (L = 3.5 H) are connected in series across a 240 Hz AC source for which ?Vmax = 145 V. Calculate the following. (a) the impedance of the circuit ? (b) the maximum current delivered by..
A steel ball rolls by constant velocity across a tabletop 0.950 m high. It rolls off and hits the ground 0.352 m from the edge of the table. How fast was the ball rolling?
Consider on an inclined air track, the inclined angle is 2 degrees. If in our experiment, find the distance d between the two photogates
As we've seen, astronauts measure their mass by measuring the period of oscillation when sitting in a chair connected to a spring. What is the mass of an astronaut who oscillates with a period of 2.25 when sitting in the chair
Two parallel slits are illuminated by light composed of two wavelengths, on of which is 645 nm. On a viewing screen, the light whose wavelength is known produces its third dark fringe at the same place where the light whose wavelength is unknown ..
