To initiate a nuclear reaction, an experimental nuclear physicist wants to shoot a proton into a 5.50-fm-diameter 12C nucleus. The proton must impact the nucleus with a kinetic energy of 3.00 MeV. Assume the nucleus remains at rest.
a. With what speed must the proton be fired toward the target?
b. Through what potential difference must the proton be accelerated from rest to acquire this speed?
Explain why the observation of alpha particles scattered at very large angles led Rutherford to reject Thomson’s model of the atom and to propose a nuclear model.
FIGURE Q37.6 shows a magnetic field between two parallel, charged electrodes. An electron with speed passes between the plates, from left to right, with no deflection. If a proton is fired toward the plates with the same speed ,will it be deflected up, deflected down, or pass through with no deflection? Explain.
Event A occurs at spacetime coordinates (300 m, 2 s)
a. Event B occurs at spacetime coordinates (1200 m, 6 μs). Could A possibly be the cause of B? Explain.
b. Event C occurs at spacetime coordinates (2400 m, 8 μs). Could A possibly be the cause of C? Explain.
4. What was the significance of Thomson’s experiment in which an off-center electrode was used to collect charge deflected by a magnetic field?
