Due to the wave nature of light, light shined on a single slit will produce a diffraction pattern. Green light (520 nm) is shined on a slit with width 0.420 mm.
(a) Find the width of the central maximum located 1.75 m from the slit
_____m
(b) What is the width of the first order fringe?
________m
A parallel-plate capacitor is formed of two 10 cm x10 cm plates spaced 1.0 cm apart, What is the slowest speed the electron can have if it is to reach the negative plate
The loaded cab of an elevator has a mass of 3.6 x 10^3 kg and moves 193m up the shaft in 20s at constant speed. At what average rate does the force from the cable do work on the cab.
A car starts from rest and accelerates at a constant rate of 3.00 m/s^2 until it is moving at 18.0 m/s. The car then decreases its acceleration to 0.500 m/s^2 and continues moving for an additional 250 m. Find the total time taken.
