Undergrad Parseval's equality and theorem?
It's kind of dumb question.. But, I just wanted to make sure. Are Parseval's equality and Parseval's theorem same thing? (In terms of Fourier series) i.e. do both mean \frac{1}{L}\int_c^{c+2L}|f(x)|^{2}dx = \frac{a_0^2}{2}+\sum_{n=1}^{\infty}[|a_n|^{2}+|b_n|^{2}]- car202

How much fuel is needed to reach a specific velocity in rocket propulsion?
My only question is, on equation Ve(dm/dt) = M(dv/dt), how do we get dv/dt? I really don't get it..Is it constant?- car202

How much fuel is needed to reach a specific velocity in rocket propulsion?
well i got some answer..but all of them were wrong. Ve(dm/dt) = M(dv/dt), Vf-Vi= Ve(ln(Mi/Mf)...As it reaches outer space, I got acceleration of 43.38 and since gravity is not acting, added 9.81 to get 53.19. I set this to dv/dt. Got Ve. And plugged into formula...but did not work. What's wrong?- car202

How much fuel is needed to reach a specific velocity in rocket propulsion?
Homework Statement The space shuttle, with an initial mass M = 2.41E+6 kg, is launched from the surface of the Earth with an initial net acceleration a = 26.1 m/s2. The rate of fuel consumption is R = 6.90E+3 kg/s. The shuttle reaches outer space with a velocity of vo = 4632 m/s, and a mass of...- car202

Friction Question: Finding Time and Distance with Kinetic Coefficients
Homework Statement A block of mass m = 2.20 kg rests on the left edge of a block of larger mass M = 6.90 kg. The coefficient of kinetic friction between the two blocks is 0.310, and the surface on which the 6.90 kg block rests is frictionless. A constant horizontal force of magnitude F =...- car202

Schools Participating IPhO-but going college two years late.
I really can't decide which one to choose. I studied college physics and analytical mechanics.-very deeply. So I'm pretty sure that I can earn some medals in IPhO. At least it will be very nice experience. But one thing-I can't participate this year and next year's IPhO-due to some...- car202

Actually, I don't know what is benefits to go top school. So what I'm thinking is concentrating more on physics during high school years. The only problem with this is that I can't go to top school perhaps. what do you think?- car202
