Answer:
Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less).
Explanation:
A. acceleration.
On a Velocity vs Time graph the slope will always be equal to the acceleration. I.e. if the slope is negative, so is the acceleration and vice versa.
∆v = -5 m/s
∆t = 5 s
a = ∆v/∆t = (-5 m/s)/(5 s) = -1 m/s^2 .
I know that's the right answer.
I THINK that's what choice-B is trying to say.
