Light waves with two different wavelengths, 632nm and 474nm, pass simultaneously during a single slit whose width is 7.5 x10-5m and strike a screen 1.20 m from the slit. Two diffraction patterns are formed on the screen. What is the distance (in cm) between the common center of the diffraction patterns and the first occurrence of a dark fringe from one pattern falling on top of a dark fringe from the other pattern?
A dance studio has flat mirrors on opposite walls, and multiple images are observed when a person stands between them, What is the image distance for the first image behind the north mirror
Water is forced out of a fire extinguisher by air pressure, as shown in Figure P9.64 where h = 0.495 m. How much gauge air pressure in the tank
The x -component of the velocity of an object vibrating along the x - axis obeys the equation vx(t)= (0.445 m/s) sin [(25.4rad/s)t + 0.223]. Find the maximum acceleration of the vibrating object
a sprinter explodes out of the starting block with an acceleration of 3.6 ms2 which she sustains for 1.2 s. then her
The ratio rX/rT of the radius of an unknown nucleus AZX to a tritium nucleus 31T is rX/rT = 1.10. Both nuclei contain the same number of neutrons. Identify the unknown nucleus in the form AZX.
A spider hangs from a strand of silk whose radius is5.8x10-6 m. The density of the silk is 1100kg/m3. When the spider moves, waves travel along thestrand of silk at a speed of 310 m/s. Determine the mass of the spider.
suppose that the speed of light in a vacuum were one million times smaller than its actual value c 3.00 times 102 ms.
