Two narrow slits 50 micrometers apart are illuminated with light of wavelength 500 nm . What is an angle of the m=2 bright fringe in radians? in degrees.
Determine out the work completed to move the particle from x = 0 to x_3 = 10.5 m graphically by determining the area under the F_x vs. x graph.
A vertical containery with base area measuring 14.0 cm by 17.0 cm is being filled with identical pieces of candy, each witha volume of 46.0 mm3 and a mass of 0.0208 g.
A 2.8 kg block slides along a frictionless horizontal with a speed of 5.5 m/s. After sliding a distance of 8m, the block makes a smooth transition to a frictionless ramp inclined at an angle of 43 degrees to the horizontal. The acceleration of gravit..
During the same interval, a 34 kg greyhound can accelerate from rest to 23 m/s. Calculate (a) the change in kinetic energy and (b) the average power output for each.
A wrecking ball (weight = 4600 N) is supported by a boom, which might be assumed to be uniform and has a weight of 3600N. As the drawing shows, a support cable runs from the top of the boom to the tractor. The angle between the support cable and t..
How many liters of gasoline would give the same mechanical energy given that each liter provides 8.50x10^6 J of mechanical energy.
A string is wrapped around the disk of mass m = 1.8 kg and radius R = 0.11 m. Starting from rest, you pull the string with a constant force F = 8 N along the nearly frictionless surface. At an instant when the center of the disk has moved a distan..
A block is given an initial velocity of 5 m/s up a frictionless 19° incline. How far up the incline does the block slide before coming (momentarily) to rest.
Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of -0.6020 N when separated by 50 cm, center-to-center.
If the average frequency emitted by a 200,-, rm W light bulb is 5.00 times 10^ {14}, {rm Hz}, and 10.0 percent of the input power is emitted as visible light, about how many visible-light photons are emitted per second.
Styrofoam has a density of 300 kg/m^3 . What is the maximum mass that can hang without sinking from a 20.0cm -diameter Styrofoam sphere in water? Assume the volume of the mass is negligible compared to that of the sphere.
