A radiography contingent are carrying out industrial radiography. A worker accidentally crossed a barrier exposing themselves for 15 seconds at a distance of 2 metres from an Ir-192 source of approximately 200 Bq worth of activity. What dose would they have received during the time they were exposed?
In the following figure the circuit to the left has a switch thatat t = 0 s is switched and disconnects the battery from the circuit. The state depicted on thefigure is right after the switch, still t = 0. As the current decreases over time, the magneticflux through the circuit on the right (due to the long cable of the circuit on the left) changesand induces an EMF on the right circuit. How much power is consumed by R2 as a functionof time.The distance between the wire on the left and the closest wire on the right is r = 2.0 cm.The size of the circuit on the right is noted on the figure.

The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. Two parallel, horizontal rails extend from left to right, with one rail behind the other. A cylindrical rod rests on top of and perpendicular to the rails at their left ends. The distance between the rails is d and the length of the rails is L. The magnetic field vector B points vertically down, perpendicular to the rails. Within the rod, the current I flows out of the page, from the rail in the back toward the rail in the front. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 T. The electromagnetic force on the rod…arrow_forward
