Answer:

\boxed{\bold { \large { \boxed {KE=\frac{1}{2} mv^2 \ , \ PE=mgh}}}}

Explanation:

Kinetic energy formula

\displaystyle KE=\frac{1}{2} mv^2

Potential energy formula

\displaystyle PE=mgh

\displaystyle KE \Rightarrow \sf kinetic \ energy \ (J)

\displaystyle PE \Rightarrow \sf potential \ energy \ (J)

\displaystyle m \Rightarrow \sf mass \ (kg)

\displaystyle v \Rightarrow \sf velocity \ (m/s)

\displaystyle g \Rightarrow \sf acceleration \ of \ gravity\ (m/s^2)

\displaystyle h \Rightarrow \sf height \ (m)

A battery charger is connected to a dead battery and delivers a current of 8.9 A for 4.7 hours, keeping the voltage across the b
adell [148]

Answer:

1807.56 kJ

Explanation:

Parameters given:

Current, I = 8.9A

Time, t = 4.7hrs = 4.7 * 3600 = 16920 secs

Voltage, V = 12V

Electrical energy is given as:

E = I*V*t

Where I = Current

V = Voltage/Potential differenxe

t = time in seconds.

E = 8.9 * 12 * 16920

E = 1807056 J = 1807.056 kJ
