A laser beam is incident on a 600 lines per millimeter diffraction grating. The wavelength of the light produced by the laser is 630 nm and the interference pattern is observed on a screen 2.00 m from the grating. Determine
a) angular deflection of the first-order bright fringe,
b) angulardeflectionofthesecond-orderbrightfringe,
c) the maximum number of bright fringes that can be observed.
By how much does the ball clear the net. How far below top surface would the medallion appear if the observer (not wearing goggles) and the block were under water.
A 69.00 kg person on skis is going down a hill sloped at 30° from the horizontal. The coefficient of friction between the skis and the snow is 0.20. What would be magnitude of the acceleration.
Find out the average magnitude of the induced emf if the change in shape occurs in 4.24 {rm s} and the local 0.120-{rm T} magnetic field is perpendicular to the plane of the loop.
A 5.20 microFarad parallel-plate air capacitor has a plate separation of 5.00mm, Calculate the energy density in the region between the plates, in units of J/m^3
A 2.47 kg steel ball strikes a massive wall at 11.7 m/s at an angle of alpha = 67.2° with the plane of the wall. It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.218 s, what is the magnitude of average force..
An initially motionless test car is accelerated uniformly to 145km/h in 8.28s before striking a simulated deer. The car is in contact with the faux fawn for .815s, after which the car is measured to be traveling at 82.0km/h. What is the magnitude ..
