The emf of a battery is: Group of answer choices the force per charge it provides the energy it provides the work per Coulomb it provides the power it provides the current it provides

work per coulomb it provides

Explanation:

Emf of electromagnetic force is defined as work done per unit charge or per coulomb charge to move 1 coulomb of charge around the circuit.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
