The total power delivered by the battery if the lightbulbs are connected is V^2/9R
<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 are in series, then;
RT = R + R + R
RT = 3R
The voltage drop across each lightbulbs will be the same for parallel connection, hence;
Power = 3(V/3)^2/(1/3R)
Power = V^2/9R
Hence the total power delivered by the battery if the lightbulbs are connected is V^2/9R

Answer:
If an object accelerates from rest, with a constant acceleration of 5.4 m/s2, what will its velocity be after 28s? v0 = 0 v= ? a = 5.4 m/s2. ∆x = t = 28 s. 3.

Answer:
Depends on the person, if you are hooked to your phone which most people are these days, you might go a little crazy. But think cavemen or anybody long ago, they survived without electricity. People in Africa bathe in the lake or any water nearby, they also walk for miles just to get drinking water. So yes, if you really tried you could go without electricity for possibly your whole life. It sucks if you have homework though because you don't have Brainly :)
