Intense white light is incident on a diffraction grating that has 465 lines/mm. (a) What is the angular separation between the violet edge (400 nm) and the red edge (700 nm) of the first order spectrum produced by the grating?
The mass of Mercury is 0.0550 times that of earth, and its radius is 0.380 times that of earth, Calculate the average density of Mercury (in kg/m3) given the earth's density is 5.52×103 kg/m3
The spring is kept from pushing them apart, since they are holding each other. When they release their arms, Al moves off in one direction at a speed of 1.16m/s, while Jo moves off in the opposite direction at a speed of 0.973m/s. Assume that frictio..
The spring is aligned with the plane and has a spring constant of 133 N/m. Explain how much does the spring stretch?
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
Blocks A (mass 4.50 ) and B (mass 13.00 ) move on a frictionless, horizontal surface. Initially, block B is at rest and block A is moving toward it at 7.00. Find the velocity of each block after they have moved apart
A diffraction grating produces a first order bright fringe that is 0.226 m away from the central bright fringe on a flat screen which is 0.675 m away. What is the wavelength of the light shining on the grating
A 3500 kg block falls vertically through 5 m and then collides with a 400 kg pile, driving it 3.0 cm into bedrock. Assuming that the block-pile collision is completely inelastic, find out the magnitude of the average force on the pile from the bed..
What is modify in frequency ff - fi
A mass of 0.006 kg is attached to a spring that requires a force of 0.01 N to extend it 0.05 meters greater than its natural length, Find maximum velocity of spring when released from rest
A 16.0-? resistor, a 12.0-µF capacitor, and a 17.0-mH inductor are connected in series with a 155-V generator. At what frequency is the current a maximum
A circular conducting loop of radius 11.0 cm is located in a region of homogeneous magnetic field of magnitude 0.300 T pointing perpendicular to the plane of the loop. Calculate the magnitude of the induced emf in the loop
Basilisk lizards can run across the top of a water surface. With each step, a lizard first slaps its foot against the water and then pushes it down into the water rapidly enough to form an air cavity around the top of the foot.
