Science & Mathematics - 31 January 2007

After I was flying a remote control airplane, I had a picnic with my friends. One of them brought honey and this idea popped into my head.

Also, if gravity is the weakest of the elementary forces, why do things fall to earth instead of being reflected by the charge in aerial particles or the ionosphere? I know this is more of a fluid dynamics question, but I'm wondering why does it matter how many atoms there are to get in the way of another body. Shouldn't some of the atoms get trapped in between the descending body and the earth so that there's a point where the object just floats above the earth, or is air pressure what we call the resistance applied by the atmosphere's atoms which are repelling the falling object (then, as the object approaches the ground, the imperfect positioning of the air's atoms results in it getting squished out to the side from between the falling object and the ground)?

what volume in liters of methane must be burned?

Assume that 3.65 x 106 kJ are needed to heat a swimming pool. If this energy is derived from the combustion of methane (CH4) at standard conditions (25 oC and 1 atm) what volume in liters of methane must be burned?

The heat of combustion of methane is 889.967 kJ/mol. The density of methane is 0.0680 kg/

Parametric Equations?

Eliminate the parameter to find a Cartesian
equation from these parametric equations,
x(t) = cos2(48 t) and y(t) = sin2(48 t) .
1. y(x) = 1 + x
2. y(x) = 1 + 48 x
3. y(x) = −1 + x
4. y(x) = 1 − 48 x
5. y(x) = −48 − x
6. None of the other choices is correct.
7. y(x) = −1 − x
8. y(x) = −48 + x
9. y(x) = 1 − x
10. There is no such Cartesian equation

Photosynthesis question?

Suppose a plant is given water labeled with the radioactive isotope 18O and normal, unlabeled CO2. What products would you expect to see containing this isotope after the plant had been allowed to photosynthesize for a while? What if the plant had been given CO2 labeled with 18O and normal water. Explain your answers.

work and power output-- Help please, don't know what Im doing?

A helper lifts 35 bricks to the top of a 2.8 m wall. Each brick weighs 1300g.
how much work is done neglecting the weight of his own hands to lift all the bricks?

Is it w=mg------9.8*2.8=27.44m/s^2 or w=fXd=1300*35=45,500*2.8=127,400

It takes 3 mins to lift the bricks....what is his power output?

---1300g/1000=1.3
1.3*35=45.5
45.5*2.8=127.4/3s=42.5s
or 27.44/3s= 9.1?

a motor driven conveyor produces 3000W of useful output. It carries the bricks to the top of the wall. how long would the conveyor take to lift the blocks?
