Homework Statement
Fit P(w) to determine Q, and w_0, and R. You should put in Vrms as a known constant.
Homework Equations
P(\omega)={\frac{V_{rms}^{2}}{R(1+Q^2(\frac{\omega}{\omega_0}-\frac{\omega_0}{\omega})^2)}
Q=\frac{\omega_0}{\Delta\omega}
R=R_load+r

Hi. I'm not sure if this is the right place to pose this question as it is not homework question.
I'm studying RC circuits in second semester physics and I have a question about the electrons traveling through a circuit. Is it true that electrons won't travel down a branch of a circuit in...

I have some results of my lab here and I just want to check to make sure they make sense. The lab write-up refers to this part of the experiment as "capacitors in parallel" but I think they are actually in series (either that or we connected them incorrectly).
Here is...
Conservation of energy was my second attempt. I set it up as this:
P.E. + K.E. = K.E. + P.E.
OH!!!!!!!!!!!! I see. Dang, for some odd reason the first time I tried this approach I used 9.8 as the value for P.E. ...how foolish. I see now. Thank you so much. Man, I cannot afford to...

A sailboat is heading due east at 8 mph. The wind appears to blow from the south west (toward the north east – that is 45 degrees north of east) as observed from the sailboat. What is the speed and direction of the wind as observed from the ground?

I am still not understanding this. I have some experience with vector arithmetic. I believe that I understand the concept. Most importantly I understand:
"The velocity of the rain relative to the car is the difference between the velocity of the rain relative to the ground and the velocity...
Thank you for your response.
Everything you have said makes sense to me except for one part. I drew the first vector (the velocity of the rain drop relative to the ground) from the origin towards the positive x-axis with an angle of 0 going counterclockwise from the origin. Is this right...
I believe the angle is 116.35. Draw and solve the right triangle using your coordinates. Then, you can use the other trig functions to get the correct angle.
I am sure there is a more sensible approach to my solution, but this was the first that came to my mind.
Homework Statement
While driving north at 25 m/s during a rainstorm you notice that the rain makes an angle of 38 degrees with the vertical. While driving back home moments later at the same speed but in the opposite direction, you see that the rain is falling straight down.
From these...
That helped a lot. Thank you very much. I see now that my post was extremely confusing. I'm sorry about that. I reviewed my FBD drawing skills and I understand exactly where I went wrong. I really appreciate your time.
Does anyone know how to mark this as solved? I looked under thread...

Homework Statement
There is a box drawn on a horizontal surace. A force is being applied at an unkown angle in the positive x direction to the box. The angle is greater than 0 and less than 90. I'm assuming a standard coordinate system.

Yes it would. I realized that I made that error after I left the computer. So, I'm guessing you could calculate the change of the slope of the tangent line.
