a student standing on a train staiton observes that the pitch (frequency) of the train decreases from 888.8 Hz to 862.8 Hz as it travels past the student at a constant speed. What is the speed of the train? assume that the velocity of sound is 340.0 m/s.
An electron of kinetic energy 1.56 keV circles in a plane perpendicular to a uniform magnetic field. The orbit radius is 21.8 cm. determine the circling frequency
A neutron turns into a proton and an electron. The electron goes in one direction and the proton goes in the opposite direction. find the maximum separation distance of the two particles
A 70 turn coil of radius 4.6 cm rotates in a uniform magnetic field having a magnitude of 0.45 T. find the magnitude of the maximum torque exerted on the coil
Four (and only four) full spectral orders can be seen on either side of the central maximum, find the maximum number of slits per cm for the grating
A 54 N crate is suspended from the left end of a plank. The plank weighs 21N, but it is not uniform, so its center of gravity does not lie halfway between the two ends. The system is balanced by a support that is 0.3m from the left end of the plan..
A thin square metal plate is 1.00 m on a side is located in the xz-plane. A charge of 400 nC is placed on the plate and can be taken to be distributed uniformly.
A motorcycle accelerates uniformly from rest and reaches a linear speed of 22.0 m/s in a time of 9.0 s. What is the angular acceleration of each tire
A parallel-plate capacitor is constructed using a dielectric material whose dielectric constant is 2.70, Find the minimum area of the capacitor plates
Another approach to the Lorentz Transformations. Relativists often use a quantity calledrapidity to describe the frame transformations. determine the function f(R)
A dentist's drill starts from rest. After2.90s of constant angular acceleration it turns at a rate of2.2104rev/min. Find the drill's angular acceleration
A circuit consists of two 150.?k? resistors in series with an ideal 12.0?V battery. Calculate the potential drop across one of the resistors
The index of refraction for violet light in plastic is greater than that for red light by 0.0410. Delaying any rounding off of calculations until the very end, find the index of refraction for violet light in plastic.
