The total power delivered by the battery if the lightbulbs are connected is 9V^2/R
<h3>Power of a battery</h3>
The formula for calculating the power of a battery is expressed according to the equation;
Power = v^2/RT
where
R is the total resistance
v is the voltage or emf
If there are 3 identical lightbulbs, each having constant resistance R, then;
1/RT = 1/R + 1/R + 1/R
1/RT = 3/R
RT = R/3
The voltage drop across each lightbulbs will be the same for parallel connection, hence;
Power = 3V^2/(R/3)
Power = 9V^2/R
Hence the total power delivered by the battery if the lightbulbs are connected is 9V^2/R

I think 36m/12s because 3×12 =36
The answer is 24N. Since the body is moving with constant velocity all the forces must balance (equal & opposite)
Answer:It increases confidence because the more times you conduct the same experiment over and over should either prove your hypothesis right and wrong and eliminate any random occurrences that might affect your results.
