Acircuit consists of a series combination of 6.50 −kω and 5.00 −kω resistors connected across a 50.0-v battery having negligible internal resistance. you want to measure the true potential difference (that is, the potential difference without the meter present) across the 5.00 −kω resistor using a voltmeter having an internal resistance of 10.0 kω.
part a: what potential difference does the voltmeter measure across the 4.50 kohm resistor?
partb: what is the true potential difference across the resistor when the meter is not present?
part c: by what percentage is the voltmeter reading in error from the true potential difference?

9. an object is moved from the outdoors, which is at a temperature of 100 ºf, to a room at a temperature of 70 º f. what happens to the object when it’s placed in the room with a lower temperature? the object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same. the object gives off the same amount of energy as it absorbs until it reaches a new lower thermal equilibrium where the amount of energy given off is greater than the amount of energy it absorbs. the object gives off more energy than it absorbs until it reaches a new higher thermal equilibrium where the amount of energy absorbed and given off is the same. the object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
