The figure shows the light intensity on a screen behind a double slit. The slit spacing is 0.210mm and the screen is 2.10m behind the slits.
1. What is the wavelength of the light in nanometers?
2. What is the distance from the center of the pattern to the 15th order minimum (in cm)?
A 30nC charged particle and a 50nC charged particle are near each other. what is the magnitude of the electric field at its original position
what height above the ground level
A 15.0 kilogram stone and a 150 kilogram stone are released from rest at the same height above the ground. Do both stones have the similar initial gravitational potential energy
A cube is constructed of six copper plates joined at the edges by an insulating material. find the electrical potential in the center of the cube
A long solenoid that has 1,160 turns uniformly distributed over a length of 0.350 m produces a magnetic field of magnitude 1.00 x 10-4 T at its center. What current is required in the windings for that to occur
suppose that the engineer is at x = 0 when, at t = 0, he first spots the locomotive. Sketch x(t) curves for the locomotive and high-speed train for the cases in which a collision is just avoided and is not quite avoided.
Assume that the pressure in a room remains constant at 1.01 x10^5 Pa and the aire is composed only of nitrogen. The volumeof the room is 60.0 m^3. what mass of air (in kg) escapes from the room
Two masses, m1 = 20 kg and m2 = 24 kg, are connected by a rope that hangs over a pulley. Find the magnitudes of the velocities of the masses after each of the masses travels a distance d = 1.5 meter
A body with initial velocity 8 m/s moves along a straight line with constant acceleration and travels 2.7 m/s in 3 s. For the 40 s interval, find the acceleration, the average velocity, the final velocity
When you weigh yourself on good old terra firma (solid ground), your weight is 144 lb . In an elevator your apparent weight is 124 lb.What is the magnitude of the elevator's acceleration? What is the direction of the elevators acceleration?
A very small steel marble is shown rolling at a constant speed on a horizontal table. The marble leaves the table at L, falls, and hits the ground at N. This is illustrated in the diagram below which is drawn to scale. Calculate the time it took t..
