Wikipedia sources are a bit insulting...but thanks anyway Drakkith :)

Hi All, I was just wondering why some galaxies look spiral (e.g. the milky way, andromeda, etc)? Is there a proven explanation for this? Also, it would be interesting to hear your thoughts/opinions.. Thanks! :)

What is the evidence for the existence of a white hole? Other than theoretical ones, are there any observational proofs?

I'm sorry Markus - more directly, I meant any effect of the Earth's Gravitational field on a Nuclear powerplant.

Thank you Turbo! I did not understand the term gravity power plant

Is there a relation between Nuclear energy and Gravity? If so, can you please explain what that is and why? If not, why not?

Is this really feasible? http://www.indianexpress.com/video/national/6/a-power-plant-running-on-gravity/7117 and if so, can anyone please explain to me how?

Sorry a mistake- I mean they (-vely cambered and flat airfoils) don't generate lift when they are in line with the airflow. It's easy to visualize linear airflow over an aerofoil or wing tip. It follows the shape of the body it is flowing over..

Thank you Chris!

I don't think there is a universally agreed explanation for lift generation but here's one as you wanted: Google lift curve slope. You can see from there that only airfoils with a positive camber (not flat nor negatively cambered ones) generate lift under normal conditions. This is because...

Assuming a rigid and light rope since it's near horizontal m*v^2/r=100 --> v≈2.82m/s ----> B) 13.5rpm (The ball has a vertical acceleration downwards of g-4sin(alpha). Since it's near-horizontal, alpha is approx 0, therefore sin(alpha)≈0 --> downward acceleration ≈ g)

Waves transmit energy. So when this energy is intercepted by a barrier (variable depending on the type of wave), the energy is transmitted to the molecules of the barrier which as a result move faster. Hence since their average Kinetic energy increases, shouldn't the Temperature of the barrier...

Do waves (all types of waves) cause heat (however minimal) when intercepted?

What happens at -273 oC? (everything under 1atm) I know about the cooling curve but just wondering what would happen to substances at absolute zero- does the temperature keep reducing/get harder? Also, how do gases stay in gaseous form in outer space? Many thanks in advance! :)

Thank you- your answer cleared up a number of questions! However, how can these transverse waves be converted to longitudinal sound vibrations? (As guessed I'm not a Physics Major!)
