(Young's Double-Slit Experiment)
A double-slit experiment is carried out with slit spacing d = 0.41 mm. The screen is at a distance of 1.5 m. The bright fringes at the centre of the screen are separated by a distance Ax = 1.5 mm.. a) Determine the spacing of the bright fringes when a source with a wavelength 600 nm is used.
A rocket-powered hockey puck has a thrust of 1.60N and a total mass of 2.10kg. How far does the puck land from the base of the table
if a river flows due east at 1.68m/s. a boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 13.40m/s due north relative to the water. if the river is 178m wide, how far downstream is the boat when i..
A cord of length 1.0m has two equal-length sections with linear densities of 0.50 kg/m and 1.00 kg/m The tension in the entire cord is constant. What is the ratio of the oscillatory frequencies
Two very large parallel sheets are 5.00 cm apart. Sheet A carries a uniform surface charge density of -8.30C/m2 , and sheet B, which is to the right of A, carries a uniform charge of 12.2?C/m2. Suppose the sheets are large enough to be treated as inf..
Heat and physical activity. In a bench press, a weight lifter lifts 132kg 41cm. In so doing, the athlete expends 1.2kJ. What's the heat flow involved in this process
As you walk across a synthetic-fiber rug on a cold, dry winter day, you pick up an excess charge of -58uc. How many excess electrons did you pick up
With good tires and brakes, a car traveling on dry pavement can travel 400 ft when the driver reacts to something he sees and brings the vehicle to a stop. If this is done uniformly, what is the car’s acceleration?
Two molecules interact in a complicated way that can be described by the potential energy (V) vs. separation (r) graph shown. They are placed 16 nm apart and released from rest.
In one day, a 81-kg mountain climber ascends from the 1410-m level on a vertical cliff to the top at 2208 m. The next day, she descends from the top to the base of the cliff, which is at an elevation of 1215 m.
