Two diffraction patterns are formed on the screen. What is the distance between the common center of the diffraction patterns and the first occurrence of the spot where the dark fringe from one pattern falls on top of a dark fringe from the other p..
To transmit only portions of an input wave lying on one side of an amplitude boundary, you would use a.
Since the circumference of a circle of radius r is 2p r, every time the center of mass moves a distance 2p r, the object rotates a full circle (2p radians). If this happens in a time T then. Combine these equations to find out an expression for ..
iron atoms have been detected in the sun's outer atmosphere, some with many of their electrons stripped away. What is the net electric charge(in coulombs) of an iron atom with 26 protons and 7 electrons? Be sure to include the algebraic sign (+ or..
The train on the right accelerates leftward at 0.82 m/s2.How far does train on the left travel before the front ends of the trains pass.
A diffraction grating with 330 {rm lines/mm} is 1.00 {rm m} in front of a screen. What is the wavelength of light whose first-order maxima will be 17.0 {rm cm} from the central maximum on the screen.
A student makes a simple generator by using a single square loop 24 cm on each side. The loop is then rotated at a frequency of 60 Hz in a magnetic field of 0.044 T.
Calculate the y-component of the magnetic force. How fast must the candy bar travel to have the same joules in the form of kinetic energy.
Three forces are applied to a tree sapling, to stabilize it. If F1= 282 N and F2= 355 N, find F3 in magnitude and direction. The angle between F1 and F2 is equivalent to 110 degrees.
Two negative and two positive point charges (magnitude = 3.64mC) are positioned on opposite corners of a square (each side = 0.155 m).Determine the magnitude of the force on each charge.
A novice skier, starting from rest, slides down a frictionless 34° incline whose vertical height is 128 m. How fast is she going when she reaches the bottom.
Find out the wavelengths of the light.
