A michelson interferometer is used with a helium-neon laser of wavelength 628.8 nm. A glass-walled chamber of interior length 1.005 cm is placed in one of the beams and the position of the mirror is adjusted until bright light is observed at the detector. The glass chamber is then evacuated. During the evacuation, the viewed light changes from bright to dark and back to bright nine times. What is the refractive index of air?
A construct force vector F = 2.0i + 4.0j N acts on an object as it means along a straight- line path. If the object is displacement is d = 2.0i + 5.0j m calculate the work done by vector F
A 12.0 V dc battery having no appreciable internal resistance, a 150.5 ohm resistor, an 11.2 mH inductor, and an open switch are all connected in series. what is the maximum energy stored in the inductor
An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. Illustrate what is the speed of the electron when it is 10.0 from charge 1?
The gravitational acceleration of bodies dropped near the Moon's surface is about 1.6 m/s^2. Find the time for an object dropped from rest to fall 3.0m on the Moon Find the time for an object dropped from rest to fall 3.0m on Earth.
Determine the flux of particles escaping from the exobase of Earth's atmosphere using a number density at the exobase of 10^5 particles/cm^3 and a temperature of 700K.
An x-ray tube accelerates electrons from rest at 5.0×10 14th m/s(squared) power through a distance of 20cm . (Such high accelerations are possible because electrons are extremely light.) Find the electrons'velocity after this acceleration. Find th..
