Cyclotrons are often used to bombard Oxygen-18 with a proton to create Fluorine-18. Estimate the final velocity of the proton assuming it is accelerating through 2e7 Volts.
determine the resultant displacement graphically.what is the magnitude of repulsive force pushing these two spheres apart.
At its Ames Research Center, NASA uses its large "20-G" centrifuge to test the effects of very large accelerations (hypergravity) on test pilots and astronauts. In this device, an arm 8.84m long rotates about one end in a horizontal plane, and the..
A 16.0-? resistor, a 12.0-µF capacitor, and a 17.0-mH inductor are connected in series with a 170-V generator. What is the maximum value of the rms current?
A 12 kg block is moving horizontally across a frictionless surface with a constant velocity of 25 m/s, How far does the block move before it comes to a stop
Electric charge is uniformly distributed inside a nonconducting sphere of radius 0.30 m. The electric field at a point , which is 0.50 m from the center of the sphere, is 15,000 N/C and is directed radially outward. What is the maximum magnitude o..
The aurora is caused when electrons and protons, moving in earth's magnetic field of 5x10^-5 T, collide with molecules of the atmosphere and cause them to glow. What is the radius of the circular orbit for (a) an electron with speed 1.0×10^6 and (b) ..
A shot-putter accelerates a 7.28 kg shot from rest to 14.8 m/s. If this motion takes 1.31 s, what average power was developed
If she is served 200 of coffee at 84 in a well-insulated container, how much ice at 0 should she add to obtain a final temperature of 31.
At the instant the car begins to accelerate, a truck with a constant velocity of 21 m/s passes in the next lane. Explain how far will the car travel before it overtakes the truck?
A string with a mass of 31 g and a length of 2 m is stretched under a tension of 67 N. How much power must be supplied to the string to generate a traveling wave that has a frequency of 51 Hz and an amplitude of 4 cm.
Choose one part of the photo-electric experiment that cannot be explained by assuming that light is a wave. Why do we need the concept of light as a particle?
Find the magnitude and direction of the force on a proton at x = -3.2 m, y = 0.9 m.
