The liquid-drop model of the atomic nucleus suggests high-energy oscillations of certain nuclei can split the nucleus into two unequal fragments plus a few neutrons. The fission products acquire kinetic energy from their mutual Coulomb repulsion. Assume the charge is distributed uniformly throughout the volume of each spherical fragment and, immediately before separating, each fragment is at rest and their surfaces are in contact. The electrons surrounding the nucleus can be ignored. Calculate the electric potential energy (in electron volts) of two spherical fragments from a uranium nucleus having the following charges and radii: 35e and 5.59 10-15 m, and 57e and6.58 10-15 m.
How much heat energy can created throughout motion
The wave is travelling to the right at 50.0 m/s. What is the amplitude if the highest displacement is 38.0 cm and the total distance travelled by the wave is 16.0 m.
What is the dissimilarity between sprinters and nonathletes
A dynamite blast at a quarry launches a rock straight upward, and later it is rising at a rate of 15m/s. Assuming air resistance has no effect on the rock, calculate the total time the rock is in the air.
(a) Determine the sound intensity at each of the three patches. (b) The sound power that passes through each of the patches is 2.00 10-3 W. Find the area of each patch.
A train has 4 locomotives (73 tons each) and 60 coal cars (42 tons each). The train is going down a 2.4% incline, What is the mass of the entire train
define what is the unknown capacitance. what focal length eyepiece should she use.
A second converging lens of focal lenght 12 cm is placed to the right of the first lens. If the final image of the combined lens system is virtual and 15 cm from the second lens, then compute the distance between the two lenses
A 9 m, 220 N uniform ladders rests against a smooth wall. The coefficient of static friction between the ladder and the ground is 0.55, and the ladder makes a 50° angle with ground. How far up the ladder can an 850 N person climb before ladder beg..
A 50 g ball is fired horizontally with initial speed v_0 toward a 110g ball that is hanging motionless from a 1.10 m-long string. The balls undergo a head-on, perfectly elastic collision, after which the 110g ball swings out to a maximum angle the..
There is an 80 kg beam attached to a hinge on a wall and supported by the cord. The angle between the cord and the beam is 25 degrees. The beam is 4.5 m long., and cord is attached to the beam a metre from the beam's end. There is a 20 kg beam hangin..
A speedboat moving at 30 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of negative 3.5 m/s^2 by reducing the throttle. How long does it take boat to reach the buoy.
