I understand no problem. Thank you for your help though. I will note this for future.

Is there a way you can edit your response and just delete it also the part you quoted on me. I deleted as much as I could.

How can I delete this entire post? I don't want students from my class who are lazy to google and get this easily. Can yo please remove.

Thank yo so much. I think I will use blank Hz since the problem link the professor uses the same. My professor is very laid back he will still mark it correct even if I use any frequency because he will see my work and know I know how to solve it. Thanks again!

Homework Statement Homework Equations Impedance formula and couple others.The Attempt at a Solution

Homework Statement Two metal rods, one silver and the other copper, are both immersed at one end in a steam chamber at a temperature of 100°C. The other end of each one is in an ice water bath at 0°C. The rods are 5.0 cm long and have a square cross-section that is 2.0 cm on a side. No heat is...

Thanks everyone I found a solution that shows me how to do it. Now I actually understand it and know how the units work.

Do I have to convert 1 mW to W? So would my setup be I = 1/pir^2? I think my main formula template is I=P/A

No still lost and confused. Can someone please explain equations further I am not seeing how it connects to the variables given in the question.

Homework Statement A barking dog delivers about 1.0 mW of power, which is assumed to be uniformly distributed in all directions. What is the intensity level in decibels at a distance 5.00 m from the dog? The threshold of human hearing is 1.0 × 10-12 W/m2. Homework Equations I=P/A A is...

When I caught my error I redid it and got g=(4pi^2 *L)/(T)^2

Homework Statement An astronaut has landed on Planet N-40 and conducts an experiment to determine the acceleration due to gravity on that planet. She uses a simple pendulum that is 0.640 m long and measures that 10 complete oscillations 26.0 s. What is the acceleration of gravity on Planet...

No I don't sorry. You say to connect first two to third at H. Which letter to which letter would be more helpful. This is what I have so far

Thank you for trying to explain. I have tried that method. I am a new user. I saw physics and posted in it. I did not realize there was a homework section. Can you please move my thread there if possible?

I have tried this no luck. The bottom connects the way in the pick I did which balances out the 2 kg with 2 kg. Then from there I just seem to not figure it out.
