Did you mean acceleration? “Average acceleration is the final velocity minus the initial velocity per time taken”
Change in volume = mass x coefficient of linear expansion x change in temperature
.002 x .0001802 x 30 = .000010812
initial volume + change in volume = Final volume
.002 + .000010812 = .002010812 m cubed
D) sepals
other options are ridiculous
The total charge held in a battery is 0.
