An object is placed 15cm from aconvex mirror of radius of curvature 60cm. Find the position of the image and its magnification.
A 3.49 rad/s (33rpm) record has a 5.03-kHz tone cut in the groove. If the groove is located 0.100 m from the center of the record (see drawing), what is the "wavelength" in the groove?
1. How many intrinsic electrons and holes are there in a thermal de Broglie cube at 300K in Si corresponding to an energy equal to k B T? What is the thermal fluctuation in carrier density In this cube? Can the intrinsic ...
A life preserver is manufactured to support a 76 kgperson with 25 %of his volume out of the water. If the density of the life preserver is 100 kg/m3 and it is completely submerged, what must its volume be? Assume that th ...
Draw to scale the three electron energy level and transition energy diagrams of the isolated neutral He atom (with two electrons) and the He+ lon (with on electron) in analogy to Figure (a)-(c) but taking into account th ...
Si, GaAs and CdS crystals are exposed to a yellow light of wavelength 5500A and intensity 10 12 photons/cm 2 -sec. Verify that the photon energy Is 2.25eV. How many electron-hole pairs are generated per unit volume per ...
A ball is dropped from the top of the Empire State building to the ground below. The height, y, of the ball above the ground (in feet) is given as a function of time, t, (in seconds) by y = 1250 - 16t 2. (a) Find the vel ...
1. Show that it is possible to have a higher electron conductivity than hole conductivity in a p-type Si. P-type is defined by P>N. This is again impractical and gives false impression for the same reason as above. 2. A ...
