Each resistor in the three circuits in the drawing has the same resistance r, and the batteries have the same voltage v. the values for r and v are 5 ω and 6.0 v, respectively. determine the total power delivered by the battery in each of the three circuits.

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)
