A glass sheet 1.30 x 10-6 meter thick is suspended in air. In reflected light, there are gaps in the visible spectrum at 538 nm and 615.00 nm. Evaluate the minimum value of the index of refraction of the glass sheet that produces this effect.
q1. a superball with a mass of 62.50 g is dropped from a height of 1.70 m. it rebounds to a height of 1.47 m.what is
How fast in kilometres per hour, should a sound source be moving toward you to make the observed frequency 5.0% greater than the true frequency? (Suppose that the speed of sound is 340 m/s.)
A cylinder of length L = 18 cm and radius R = 5.4 cm has its center at the origin and its axis along the x axis such that one end is at x= +9 cm , What is the net charge inside the cylinder
The kiloton, which is used to measure the energy released in an atomic explosion, is equal to about 4.02 x 1012 J (approximately the energy released in the explosion of 1,000 tons of TNT). Recalling that 1 kilocalorie of energy raises the temperature..
The cross-section of a hollow cylindrical conductor with radii a = 0.90 cm and b = 4.70 cm which carries a current 7.00 Amps uniformly spread over its cross-section. Find the magnitude of the magnetic field at a distance of 2.10 cm from the axis.
what is the index of refraction of the jelly? 2 glass plates are parallel and between is jelly 0.015mm thick. the glass has an index of refraction 1.53, the plates are each 8.00 cm long, 10 dark fringes are 6.33mm apart. wave length is 525nm .
A rod suspended on its end and acting as a physcial pendulum swings with a period of T=1.49 sec. What is the length of this physical pendulum
A railroad car of mass 3.5*104 kg moving at 3.50 m/s collides and couples by two coupled railroad cars, each of the same mass as the single car and moving in the similar direction at 1.20 m/s. How much kinetic energy is lost in the collision?
A 60·kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 340·N. What is the final speed of the crate
A proton is in a vacuum near the surface of Earth. Where should a second proton be placed so that the electrostatic forceit exerts on the first proton balances the weight of thefirst proton?
