Plutonium decays radioactively by emitting an alpha particle from its nucleus. The mass of the alpha particle is 6.6 x 10^-27 kg and the particle has 2 protons and 2 neutrons. If the alpha particle comes from the surface of the Plutonium nucleus, what is its greatest acceleration?
A photon with a wavelength 4.40 scatters from an electron initially at rest. Find out the wavelength of the scattered photon when the scattered electron has its utmost kinetic energy. Kmax = 2.37*20^-14.
the diameter of the vessel is 5.6 mm. In a 0.60-T magnetic field illustrate what is the magnitude of the voltage that is measured with the electrodes in the drawing?
What is x and y coordinates of the shell
What is the charge density on the surface. suppose that air resistance can be neglected.
For instance, the flute can be described as an open-open pipe because a flutist covers the mouthpiece of flute only partially. Meanwhile, a clarinet can be described as an open-closed pipe as the mouthpiece of the clarinet is almost completely closed..
Two children, Mary and Kate, are riding on a merry-go-round. Mary is at a greater distance from the axis of rotation than Kate. Which child has the larger angular speed? Tangential speed? Centripetal acceleration?
A 175 watt motor is used to lift a 129 kg container to a height of 7m. How much time does it take to lift container with the motor.
Two small spheres, each with mass m = 3.1 g and charge q, are suspended from a point by threads of length L = 0.23 m
Your roommate is working on his bicycle and has the bike upside down. He spins the 66.0cm -diameter wheel, Find the pebbles speed and acceleration
On a workday the average decibel level of a busy street is 72.0 dB, with 100 cars passing a given point every minute. If the number of cars is reduced to 50 every minute on a weekend, what is the decibel level of street.
The wheel of a car has a radius of 0.365 m. The engine of the car applies a torque of 284 N · m to this wheel, which does not slip against the road surface. Since the wheel does not slip, the road should be applying a force of static friction to t..
We know that a spherical charged particle of will have an external electric field of E = k q/r2, where k = 8.988×109N·m2·C-2 is the Coulomb constant, q is the charge, and r is the distance from the center of the spherical particle.
