If the car is 4000kg, this is not the correct potential energy. Find the correct potential energy. Then maybe think about what happens to the potential energy, that is, where does it end up?

So now you know k, and all that is left is...

For part a, maybe try thinking about the divers energy. What are the expressions you listed?

Try: V = mgh Then just figure out what the initial height is.

Thanks for the reply. I don't think I am following what you are saying. I shouldn't have used x and y. Let me write this problem in a different way: f_{n_1,n_2} = \frac{n^{2}_{1}}{4}+\frac{n^{2}_{2}}{9} where n_1 and n_2 are positive real integers n_1:\left\{1, 2, 3,...,N}\right\}...

Homework Statement Hi. I came across this problem last week and in order to solve it, I had to resort to excel. I believe there is a smarter way, but I can't seem to figure it out. Given f(x,y)=A(1+\frac{x^2}{4}+\frac{y^2}{9}) Where "A" is a constant, "x" and "y" are integer valued...

I agree with your description. So, then would you say that in the original circuit, the voltage of one of the leads of the volt-meter closest to the anode power is at the same voltage as the center of the filament? If so, then that seems to imply that the resistors maintain the filament...

Thanks again for replying. Hmm, I am still having trouble understanding. It seems to me that the potential at the center of the filament is dependent on the resistance of the filament. It seems as though the filament being modeled as resistor-center-resistor requires each "resistor" to be 100...

Yes, I understand how the filament is acting like a resistor. I do not understand why you say that the potential in between the 100 ohm resistors is the same as the potential at the filament center. Can you explain why you say the resistors have that effect?

Thanks for responding. I do believe the filament acts like a resistor. I do not understand why you say that the center tap of a voltage divider would be the same potential as the center of the filament. Could you explain a bit more?

Homework Statement Hello. I am having trouble understanding the simple circuit diagram that is attached. I need to explain what the function of the two resistors are. I know some basic things about circuits (Ohms law, Kirchoffs loop rules,etc.) but I do not know exactly how a vacuum tube...
