an electron and a proton are each accelerated through a potential difference pf 10.0 million volts. Find the momentum ( in MeV/c) and the kinetic Energy ( in MeV) of each and compare with the results of using the classical Formular.
A 1200 N uniform boom is supported by a cable perpendicular to the boom, as in Figure P8.28. The boom is hinged at the bottom, and a 2000 N weight hangs from its top. Find out the tension in the supporting cable and the components of the reaction ..
Assume that the blocks accelerate as shown with an acceleration of magnitude a= 0.550 m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is μ= 0.400. Find out the mass of block 2, m2, when θ= 30.0.
Two loudspeakers on a concert stage are vibrating in phase. A listener is 57m from the left speaker and 30m from the right one. The listener can respond to all frequencies from 20 to 20 000 Hz.
Physics - Speed and Direction, Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next.
A cannonball launched with an initial velocity of 131 m/s at an angle of 40° follows a parabolic path and hits a balloon at the top of its trajectory.
An electron and a proton are initially very far apart (effectively an infinite distance apart). They are then brought together to form a hydrogen atom, in which the electron orbits the proton at an average distance of 5.40 10-11 m. What is EPEfina..
Determine the magnitude of the emf induced in the loop after exactly time 6 has passed since the circumference of the loop started to reduce.
A child on the merry-go-round is moving with a speed of 1.15 m/s when 1.10 m from the center of the merry-go-round.

A 25 kg cannon shell is subjected to a constant acceleration of 1200 g while in the cannon barrel. What force is the burning propellant exerting on the shell?
When an 82.0-kg adult uses a spiral staircase to climb to the second floor of his house, his gravitational potential energy increases by 2 x 10^3 J. By how much does the potential energy of a 17 kg child increase when the child climbs a normal sta..
