Answer is b because the other options dont literally make sense to what the question is asked... and even the heart’s function is to pump blood so b is the right answer.
Divide each by 4.7 to get ur kg/L which is 1.085kg/1L
The answer would be 1.15 kilojoules. ope this helps.
Answer: 225 joules.
Explanation:
If this a one dimension problem, this is the motion is in the same direction of the force, the equation for work is:
Work = distance × force
⇒ Work = 15 m × 15 N = 225 joules.
This is a special case of the general equation
Work = |F| |displacement| cosine (angle between the force and displacement)
When force and displacement are in the same direction, the angle is 0, so cos(0) = 1. This is the two vectors are parellel and the work is just the product of the two magnitudes (force and distance)
