Light rays in a material with index of refrection 1.29 can undergo total internal reflection when they strike the interface with another material at a critical angle of incidence. Find this material\'s index of refraction when the required critical angle is 80.1°.
If the mass of both weights is 150 gm, the first mass is located 30 north of east, the second mass is located 30 south of east, and the transducer sensitivity is 0.5 volts/Newton, how large a voltage do you expect to measure? Suppose the transducer h..
Two protons are placed at a = 4.69 cm above and below the x axis at x = 0 as shown in the figure. An electron is placed along the x axis a distance b = 10.1 cm from the origin. find the magnitude of the electrostatic force on the electron
