A double-slit experiment uses light of wavelength 633 nm with a slit separation of 0.1 mm and a screen placed 2.0 m away.
A) What is the linear width of the central fringe?
B) What is the lateral distance between 1st and 2nd order fringes?
C) What is the angular separation between the central maximum and the 1st order maximum?
A 30 g ball of clay is thrown horizontally at 20 m/s toward a 1.7 kg block sitting at rest on a frictionless hi surface. The clayts and sticks to the block. What is the speed of the block and clay right after the collision?
An airplane is flying with a velocity of 83.0 at an angle of 25.0 above the horizontal. When the plane is a distance 114 directly above a dog that is standing on level ground, the suitcase drops out of the luggage compartment.
define the magnitude of the external field. The Speed time graph of a particle moving along a fixed direction is shown below. Obtain the distance travelled by the particle between t=0 and t=10s. What is the average of the particle over this interva..
A ski starts from rest and slides down a 22° incline 75 m long. If the coefficient of friction is 0.09, what is the ski's speed at the base of the incline? If there is snow level at foot of the incline and it has the same coefficient of friction, ..
In fact, the increased normal force at these large angles makes force of friction too large to move the lawnmower at all.
A small ball rolls horizontally off the edge of a tabletop of height h, How long is the ball in the air and What is its speed at the instant it leaves the table
A 35 kg block of ice slides down a frictionless incline 1.6 m along the diagonal and 0.63 m high, Find the magnitude of the worker's force. How much work is done on the block by the worker's force
To pump 100Joules of heat from the ice cube tray of freezing water at 273K, out into a hot room at 310 K, the laws of thermodynamics say that you will need at least how many Joules of ordered energy or work.
A jetliner is moving at a speed of 235 m/s. The vertical component of the plane's velocity is 42.9 m/s. Evaluate the magnitude of the horizontal component of the plane's velocity.
In a tungsten atom, what is the kinetic energy of an L-shell electron ejected by a photon that was created during the M-K shell transition of the atom?
In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.20 m. The mug slides off the counter and strikes the floor 0.60 m from the base of the counter.
At one instant a bicyclist is 49.0 m due east of a park's flagpole, going due south with a speed of 14m/s. Then 35.0 s later, the cyclist is 49.0 m due north of the flagpole, going due east with a speed of 14m/s.
