63-48
= 15 ml
Since the water rises 15 ml in the graduated cylinder, its volume is 15 ml^3
2. 43 -36
=7ml^3
A. Increase power
The relationship between power, work, and time is:
Power = work / time
So power is the rate of work done. It is visible that power and time obey an inverse relationship, so if one wants to decrease the time taken with a constant amount of work, one would increase the power.
8 km is not a speed. And even if it were, we would still need to know how much time Charlie spent running.
To find the answer, take 55 and divide it by 1.85 to get the thickness of one card. In this case the answer would be 29.72973 cm. each.
