The speed of a light wave in a certain transparent material is 0.501 times its speed in vacuum, which is 3.00 × 108 m/s. When yellow light with a frequency of 5.25 × 1014 Hz passes through this material, what is its wavelength in nanometers?
A uniform shaft, fixed at one end & free at other, is twisted so that each cross - section rotates through an angle proportional to the distance from the fixed end. If the shaft is released from rest in this position, determine the s
Coherent light with wavelength 591 passes by two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 from the slits. The first-order bright fringe is a distance of 4.84 from the center of the central bright f..
A jeweller working with a heated 44 g gold ring must lower the ring's temperature to make it safe to handle. If the ring is initially at 94 degrees Celsius, what mass of water at 25 degrees Celsius is necessary to lower the ring's temperature to 35 d..
A block of ice at 0 degrees C, whose mass is initially 30.0 kg, slides along a horizontal surface, starting at a speed of 5.56 m/s and finally coming to rest after travelling 21.8 m. figure out the mass of ice melted (in grams) as a result of frictio..
A massless string is wrapped around a solid disk of mass m_1 and tied to a block of mass m_2. The disk is free to rotate on a frictionless horizontal axle.
How numerous years would it take a thermally insulated one-million-kilogram chuck of granite to undergo a 1000k boost in temperature?
What time would an observer on one of the two planets measure for the similar trip. Find out the coordinates of the center of gravity for this system.
the acceleration of gravity at the surface of moon is 1.6 m/s^2. A 5.0 kg stone thrown upward on moon reaches a height of 20m, find its intial velocity
A molecule in air is moving at a speed of 459 m/s. How various meters would the molecule move during 7ms if it didn't collide with any other molecules.
At time a grinding wheel has an angular velocity of 22.0. It has a constant angular acceleration of 33.0 until a circuit breaker trips at time = 2.20. From then on, the wheel turns through an angle of 431 as it coasts to a stop at constant angular de..
What is the distance between the particles at this time? The Coulomb constant is 8.95755 × 109 N • m2/C2, the elemental charge is 1.6721 × 10-19 C, and the acceleration due to gravity is 9.8 m/s2.
The amplitude of the electric field of an electromagnetic wave is 197 V/m.
