number 8 : answer should be a number with three decimal places

Question 8 10 pts A battery is used in a physics lab to supply 3.00 A to a circuit. A voltmeter connected in parallel across the cell reads 6 V in an open circuit (figure a) and 4.8 V in a closed circuit (figure b) when the cell supplies 3.00 A to the circuit. What is the internal resistance of this battery (in Ohms)? Your answer should be a number with three decimal places, do not include the unit.

A voltmeter connected in parallel across the cell reads 5.75 V in an open circuit (figure a) and 4.83 V in a closed circuit (figure b) when the cell supplies 2.7 A to the circuit. How much electrical power does the cell produce (in Watts)? Your answer should be a number with three decimal places, do not include the unit. Figure a Figure b
