An accelerator increases the total energy of electrons uniformly to 10 GeV over a 3000 m path. That means that at 30 m. 300 m, and 3000 m, the kinetic energy is 108, 109, and 1010 eV, respectively. At each of these distances, calculate the velocity, relative to light (v/c), and the mass in atomic mass units.
A sledge loaded with bricks has a total mass of 17.0 kg and is pulled at constant speed by a rope. What is the increase in internal energy in the sledge and the surface due to friction
A 220 kV power transmission line carrying 500 A is hung from grounded metal towers by ceramic insulators, What fraction of the power carried by the line in this
Energy is required to move a 1530 kg mass from the Earth’ssurface to an altitude 2.43 times the Earth’s radius RE. The acceleration of gravity is 9.8 m/s2. What amount of energy is required to accomplish this move?
A horizontal force of 2 N does nothing to move a large book along a desk, but a force of 1.8 N can keep the book sliding at constant speed on the same desk. Explain
A 35.0-cm-diameter circular loop is rotated in a uniform electric field until the position of maximum electric flux is found. evaluate the magnitude of the electric field
An electron in a hydrogen atom makes a transition from the n=6 energy state to the ground state (n=1)
We have a parallel plate capacitor with two plates containing charges +Q and -Q a distance d = 2.00 cm apart. We release a proton from rest at point A, just above the lower plate. At point B, just before the proton strikes the upper plate, the pro..
A large 50-turn circular loop of radius 10cm carries a current 4A. At the center of the loop is a small 20-turn coil of radius 0.5cm carrying current 1A. Find the torque exerted by the large coil on the small coil
The arm of a crane at a construction site is 14.4 m long, and it makes an angle of 40° with the horizontal. Assume that the upmost load the crane can handle is limited by the amount of torque the load produces at the base of the arm.
A bicycle wheel is rotating at 49 when the cyclist begins to pedal harder, giving the wheel a constant angular acceleration of 0.42. How many revolutions does the wheel make during this time
question1chlorine gas cl2 can be formed from a solution containing clminusions i.e. from naclminus by electrolysis.
A 300 kg piano slides 4.50 m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. The effective coefficient of kinetic friction is 0.40.
