Amedical cyclotron used in the production of medical isotopes accelerates protons to 6.5 mev . the magnetic field in the cyclotron is 1.4 t . part a what is the diameter of the largest orbit, just before the protons exit the cyclotron? express your answer with the appropriate units. d d = nothing nothing submitrequest answer part b a proton exits the cyclotron 1.0 ms after starting its spiral trajectory in the center of the cyclotron. how many orbits does the proton complete during this 1.0 ms ? n n = nothing orbits submitrequest answer provide feedback next

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
