A wavelength of light (625 nm) passes during a single slit with a width of 0.320mm and forms a diffraction pattern on a flat screen located 8 meters away. Decide the distance between the middle of the central bright fringe and the first dark fringe.
A 12000N car travels at a speed of40 km/h northward along a street, and an 8500 N sports car travels at a speed of 62 km/h eastward along an intersecting street. Find percentage of the initial kinetic energy will be lost in the collision
The output voltage of an AC generator is given by Δv= 780 V sin (30πt). The generator is connected across a 0.900 H inductor.Find the following. frequency of the generator. rms voltage across the inductor. inductive reactance. rms current in the in..
An object, mass 2.96kg, moves in a horizontal circle with a radius of 3.8m. The object has the intial velocity of 32.6 m s-1. If the kinetic coefficient of friction between the object and the surface is 0.31, then number of completed revolutions (..
