An x - ray tube used for cancer therapy operates at4.0 MV, with a beam current of 25 mA striking the metal target.Nearly all the power in the beam is transferred to a streamof water flowing through holes drilled in the target. What rateof flow, in kilograms per second, is needed if the rise in temperature(ΔT ) of the water is not to exceed 50.°C?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
