A particular 12 v car battery can send a total charge of 84AH through a circuit, from one terminal to other (a) how many Coulomb of charge does this represent? (b) if the entire charge undergoes a potential difference of 12v, how much energy is involved? hint: use dq = idt

what is the instantaneous acceleration of

the particle at point b?

0 meters/second?

10 meters/second?

12 meters/second?

velocity imetersisecond

15 meters/second?

20

time (seconds)

answer: 0 meters/second^2

the answer is 3.1 his answer is wrong mines is right

i think the answer is a and b

i wish you luck

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
