A teenager's heart pumps an average of 7200 L of blood every 24 hours. what is the rate of change of volume of blood? That is per 1 hour

7200/24 = x/1

7200/24 = 300/1
300 L of blood per hour.

Well, let's do some math, shall we?

If a teenager's heart pumps 7200 L of blood every 24 hours, we need to determine the rate of change per hour.

So, to find that, we'll divide 7200 L by 24 hours.

Hmmm, it seems that my calculator needs some pumping up. Hold on a second, I'm just going to squeeze it a bit.

Okay, it seems to be working now.

7200 L divided by 24 hours is... *mumbling while calculating* ...300 L per hour!

So, the rate of change of blood volume for a teenager's heart is 300 liters per hour. Just remember to keep those liters from spilling, okay? Safety first!

To find the rate of change of volume of blood per hour, we need to divide the total volume of blood pumped by the heart in 24 hours (7200 L) by the number of hours in a day.

Given:
Total volume of blood pumped in 24 hours = 7200 L

Number of hours in a day = 24 hours

To find the rate of change per hour, we can use the following formula:

Rate of change per hour = Total volume of blood pumped / Number of hours

Rate of change per hour = 7200 L / 24 hours

Simplifying the expression:

Rate of change per hour = 300 L/hour

Therefore, the rate of change of volume of blood for a teenager's heart is 300 L per hour.

particle B of mass 1.5 kg is attach to a spring of stiffness 3 Nm-1. The other end of the spring is fixed at a point A and the spring hangs vertically. A second spring, also of stiffness 3 Nm-1, is attached to particle B at one end and to a second particle C, of mass 1 kg at the other end, also hangs vertically as shown in Figure Q2. Let x and y be the displacements of the particles B and C respectively from their equilibrium positions.
