A drag racing vehicle travels from 0 100 mph in 5 seconds north. What is the acceleration

Resistors in parallel together contain less resistance than resistors in series together. Create an analogy to explain this phenomena and post it here.

Unlike the idealized voltmeter, a real voltmeter has a resistance that is not infinitely large. part a a voltmeter with resistance rv is connected across the terminals of a battery of emf e and internal resistance r.
