Answer: C. energy returned divided by energy invested.

Explanation:

The Energy Return on Investment (EROI) simply means the ratio of the amount of usable energy that is obtained from a particular resource to the amount of the energy that is being expended in order to produce the net amount of the energy.

When assessing energy resources, it is helpful to use a measure called EROI and this is the energy returned divided by energy invested.

Therefore, the correct option is C

otez555 [7]

Answer:

"1155 N" is the appropriate solution.

Explanation:

Given:

Acceleration,

a=3 \ m/s^2

Forces resisting motion,

F_f=432 \ N

Mass,

m = 241 \ kg

By using Newton's second law, we get

⇒ F-F_f=ma

Or,

⇒         F=ma+F_f

By putting the values, we get

⇒             =(3\times 241)+432

⇒             =723+432

⇒             =1155 \ N

What does a curved gradient line in a distance-time graph represent?
GREYUIT [131]

Answer:

If the line is curved, the slope is changing, which also means the velocity is changing. In a distance-time graph, the gradient of the line is equal to the speed of the object. The more the gradient (and the steeper the line) the faster the object is moving.
