Large amounts of 65zn are produced in copper exposed to accelerator beams. while machining contaminated copper, a physicist ingests 45.0 µci of 65zn. each 65zn decay emits an average γ-ray energy of 0.550 mev, 40.0% of which is absorbed in the scientist's 60.0 kg body. what dose in msv is caused by this in one day?

Which features on mars point to the possibility of liquid water on the planet? impact craters with sharp rims volcanic cones with craters gullies and stream-like channels mountain ranges with faults

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
