I don't know where you got this information but I pay 8.3k just for tuition and some of my friends who study commerce pay 10k.

There is not many bridges in Toronto but here is the one I took a picture of. http://img158.imageshack.us/img158/7530/img0608gl8.jpg

No, because water, unlike petrol, is not a source of energy. However It can be used to store energy by splitting it to hydrogen and oxygen.

Check the units.

It actually depends on a direction of rain. If a direction is straight downwards then obviously by running you would collect more water than standing still. Since if you are running you would collect not only rain drops that are falling from above but also the once in front of you.

x_f=x_i+v*cosA*t y_f=y_i+v*sinA*t+1/2*g*t^2 That is all you have to know. Where x_f - final position, x_i - initial position, A - angle with horizzontal axis, g = 9.81, v - velocity. To deal with 3-D the projectile has to be poited in the target's direction.

For the second one. The charge does not change but the capacitance does change since you decrease the distance between the plates. From Q=V*C you can see that in order for charge to stay constant, voltage has to increase in order to accommodate decrease in capacitance.

The formula for parallel plate capacitor is C = E*A/d where A - area of the plate, d - distance between the plates, E - constant. Use this equation and Q = C*V for both problems.

Check the frequency of your CRT monitor. If it is 60Hz then that is the problem. Recommended frequency is >75Hz. To reduce strain on your eyes increase the frequency and reduce brightness.

Try summing moments. Sum of moments at any point is equal to 0 N*m

Energy equals force times distance. 0.1 = F*ds where ds = (pi/3)*R, pi/3 is 1/6 of revolution. As you said T = F*R, So now you have 3 equations and 4 unknows one of which would cancel out. I hope it is helpful.

I am guessing angle can be adjusted depending on a position of the sun. During a hurricane panels can be lowered to horizontal position.

Does not portion of engine's torque has to be used to generate power for these systems? All I am saying is why not to use thermal energy to provide power for this systems. So engine itself does not have to lose some of its power. Can you really use antifreeze in steam engines?

I think it would be more logical to use power produced by steam turbine to recharge battery and to provide energy to other components. This way all the power produced by ICE can be dedicated to providing torque to the wheels. Using this design problem of torque synchronization can be avoided...

"That's the program i had in mind." That is the program that specifically informs users not to marge system partitions with any other partitions.
