by effect i mean, would it take work to move the inducing charge against the induced charge's electric field.

There is one point I am unclear upon in terms of indued charges. If a charge is induced by another charge, will the potential from the induced charge have an effect on the inducing charge. It seems that if it were the case you would be getting (increasing) energy from nothing, however if it...

dont forget about gravity it is both the force of gravity and electrostatics that allows them to keep this equilibrium. lackos

I was wondering about the first law of thermodynamics and isothemic expansion. Is there an increase in the the total internal energy of a gas through this process. If not is there a way to calculate heat (i can calculate work) through this process as both pressure and volume vary. Also is an...

sorry about redirecting you. but i think a quick wikipedia or google search should get you your info

thanks for the help and time

okay thanks for that info (note to self). so with my value (8.17), i would divide that by the speed of sound to get the extra time taken for travel. i would then form another kinematic equation factoring this in. doing this i get 8.47m does this look correct

i thought that was already factored into the the doppler equation?

Homework Statement A tuning fork vibrating at 506 Hz falls from rest and accelerates at 9.80 m/s2. How far below the point of release is the tuning fork when waves of frequency of 488 Hz reach the release point? (Take the speed of sound in air to be 343 m/s).Homework Equations...

Okay i don't know how to use imperial so i can only guide you with explanations. your equations are correct you just need this little bit of information the system is insulated therefore there is no net energy loss. the heat gained by water is the heat lost by copper i.e Q(water)=-Q(copper)...

As soon as i saw this, i was like implicit differentiation. however to go about it another way is something I am going to have to think about.

okay I am not sure if this is answering your question, but i hope it does. when you say "i formed" what do you mean, or better yet what did you do. also the kinematic equations (which are used in projectile motion) are actually derived by integrating twice from a constant acceleration...

im confused you say you are using projectile motion, however your equation for acceleration has a time dependant variable. this can't be true as the only acceleration on an object in projectile motion is that of gravity which is constant. would you mind explaining how you got that equation? please

actually for simple harmonic motion (oscillation) there is a particular formula. the formula is: (1/2)kA^2 = (1/2)mv^2 + (1/2)kx^2 where (1/2)kA^2 is the total enegy, (1/2)kx^2 is the potential energy and (1/2)mv^2 is the kinetic energy rearrange and you should be sweet :)also your method is...

Try looking at it from an energy conservation perspective. are you aware of that formula? its a much simpler method
