What I'm asking is people with longer legs can run for longer at a constant speed,

But people with short and more muscles in there legs can run faster but for shorter distances.

People with more muscles in legs, can get a better start or thrust the peole with long legs
Longer Leggers are Marthone Runners

Muscle Short Leggers are Sprinters?

A house with a 15.3 × 103 ft2 floor area and 8.00 ft high ceilings is to be heated with propane. How many kilograms of propane would be needed to raise the temperature of the air inside the house from 59.0 oF to
72.0 oF ?. In this calculation your are ignoring the temperature of the walls etc.



The moloar specific heat of the air inside the house is 30.2 J mol −1 oC −1
The average density of air over this temperature range can be estimated to be 1.22 g/L.
The molar mass of air is 29.1 g/mol.
There are 28.317 liters in a cubic foot.
The molar heat of combustion of propane is −2220.047 kJ/mol

Assume that 3.57 x 106 kJ are needed to heat a swimming pool. If this energy is derived from the combustion of liquid ethanol (CH3CH2OH) at standard conditions (25 oC and 1 atm) what volume in liters of ethanol must be burned?




The heat of combustion of ethanol is 1366.818 kJ/mol. The density of ethanol is 0.789 g/cm3

My French teacher used to do that when I was a kid - I always used to think she did it to be "cool", but I have seen others do it as well. Is it a way to differentiate the number from algebraic variables? Is there any good reason to do this in a 5th grade French class!?

I had to take Geometry this year and I absolutely hated it. I did so much better in Algebra 1 than Geometry. In Algebra, I have an 91 average as opposed to an 89 average in Geometry.

to have wall-to-wall carpeting for two rooms. One room is 9 ft by 12 ft and the other room is 12 ft by 15 ft. How much will it cost him if the carpet costs $10.50 per square yard?

I know we would multiply 9x12 and 12x15 but since its square yardage what do we divide it by?
