Atypical rechargeable deep-cycle battery for an electric trolling motor (fishing boat) delivers 10a of current at a voltage of 12v for 10 hours. (a) how much charge (in coulombs) flows through the battery in this interval? (the answer is a positive value.) (b) how much energy (in joules) does the battery deliver? (the answer is a positive value.) (c) how much energy (in watt-hours) does the battery deliver? (the answer is a positive value.)

a) 360 kQ

b) 4.32 MJ

c) 1200 W-h

Explanation:

a) The definition of the current is.

having a count that 10 hours = 36.000 s

b) The definition of the Energy in power terms is.

and the definition of power is:

replacing in the energy formula.

solving the integral, have into account that t is in seconds.

c) The energy in W-h, we can find it multiplying power by hours

explanation:

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
