A laser beam with wavelength Lambda= 6328 Å is incident normal to the plane of a diffraction grating. The grating has 550 lines per mm. If the diffraction pattern is viewed on a screen 10 cm from the grating, find the distance between the two first- order maxima in the pattern.
How many protons are in the beam traveling close to the speed of light in the Tevatron at Fermilab
A 779-kg car stopped at an intersection is rear-ended by a 1820-kg truck moving with a speed of 15.0 m/s. If the car was in neutral and its brakes were off, so that the collision is approximately elastic, find out the final speed of both vehicles ..
An object of mass 2.5 kg on a table is connected to a hanging object of mass 11.2 kg by means of a string via a pulley. Caculate the acceleration of the system
Consider an infinite solenoid of radius R, n turns per unit length, and current I. Calculate the final cinetic moment of each of the cylinders
A 0.11- kg block on a wooden table is given a sharp blow with a hammer. The block then slides across the table to a stop. How far does the block go
Coulomb's Law gives us an expression for the electric field caused by a point charge with magnitude . Suppose we have several point charges. The electric field at a location is the vector sum of point charge contributions.
The charge is uniformly distributed within volume of each sphere.How much kinetic energy does the block gain.
The position of a car at t= 20 min is x= 12 km. Its position is 69.6km when t=60min. Find the average velocity of the car
Source charge Q1= -3.00nC located at (0, 5.00mm). Source charge Q2= +2.00nC located at the origin. Find the Magnitude & direction of the net electric field
A 450 gram ball of copper at 20.0 degree C is placed in a pot of boiling water until equilibrium is reached. How much thermal energy is absorbed by the ball
The 1 kg block is tied to the wall with a rope. It sits on top of the 2 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2kg block is = 0..
