A pair of narrow, parallel slits separated by 0.147 mm are illuminated by green light of wavelength 549 nm. An interference pattern is observed on a screen 1.9 m away from the plane of the slits.
A) Calculate the distance from the central maximum to the first bright region on ei- ther side of the central maximum. Answer in mm.
Answer in units of mm.
B) Calculate the distance between the first and second dark bands. Answer in mm.
How many more revolutions would it take the disk to reach an angular speed - magnitude of the frictional force exerted by the track on the car tires to keep the car in a circle.
A uniform rod (length = 2.1m) of negligible mass has a 1kg point mass A attached to one end and a 5kg point mass B attached to the other end. The rod is mounted to rotate freely about a horizontal axis that is perpendicular to the rod and that pa..
How far from the surface will a particle go if it leaves theasteroid's surface with a radial speed of 1000 m/s
Using a fast-pulsed laser and electronic timing circuitry, you find that light travels a distance of 2.55m within a plastic rod in a time interval of 10.9ns. What is the refractive index of the plastic
A 2.50-kg ball, moving to the right at a velocity of +3.83 m/s on a frictionless table, collides head-on with a stationary 8.10-kg ball. Find the final velocities of (a) the 2.50-kg ball and of (b) the 8.10-kg ball if the collision is elastic. (c) Fi..
In an amusement park water slide, people slide down an essentially frictionless tube. They drop 2.8 m and exit the slide, moving horizontally, What horizontal distance do they travel from the exit point
three 1.50-v cells each with an internal resistance of 0.0500? are connected in series to form a battery with a
Two protons are placed at a = 5.79 cm above and below the x axis at x = 0. An electron is placed along the x axis a distance b = 11.7 cm from the origin. Decide the magnitude of the electrostatic force on the electron.
You are inside an enclosed truck with no windows and you wish to keep track of the truck's motion. To do this, you hang a mass on the end of a string, as shown. If the angle of the string is 6.2 degrees from the vertical (for zero degrees the mass ha..
A firefighter on the back of the fire engine hears the sound waves after they are reflected from the wall. What is the frequency of this reflected wave as heard by this firefighter
A 4.00 kg hollow sphere of radius 5.00 cm starts from rest and rolls without slipping down a 30.0 degree incline. If the length of the incline is 50.0 cm, then the velocity of the center of mass of the hollow sphere at the bottom of the incline is:
A ball of mass m is dropped from a height h above the ground. Calculate the speed of the ball at height y if at the instant of release it already has an initial speed of vo
