Answer:
Water is absorbing heat.
Explanation:
Water is able to absorb heat
-<u> without increasing much in temperature</u> - better than many substances.
This is because for water to increase in temperature, water molecules must be made to move faster within the water; this requires breaking hydrogen bonds, and the breaking of hydrogen bonds absorbs heat.
The rule to get the average speed is as follows:
average speed = average distance / average time
We are given that:
distance = 250 m
time = 110 sec
Substitute with the givens in the above equation to get the average speed as follows:
average speed = 250/110 = 25/11 meters/sec
You used lengths to calculate the volume.length is considered one dimensional.while volume is considered 3 dimensional.you used 3 individual dimensions their numerical lengths to find volumes of three dimensional figures.
The pumping work has the equation written below:
W = mΔh,
where m is the mass
Δh is the difference in height
We determine the mass from the density of water which is 62.5 lb/ft³.
Density = Mass/Volume
Mass = m = Density*Volume
m = (62.5 lb/ft³)(π/4)(24 ft)² = 9,000π
The lb is in lbm or pound-mass. To convert it to pound-force, lbf, we use the g/gc conversion factor which is equal to 1 lbf/lbm. Thus,
W = (9,000π lbm)(5 ft - 4 ft)(1 lbf/lbm) = 28,274 lbf·ft
