I already got a wrong, but if I
could get the work for it that would be great.
Your answer ( rho*r)/(2epsilon0) is absolutely right.

9. At an auto race, a member of the pit crew stands beside the track. A car approaches him at 110 m/s and emits a sound at frequency 1200 Hz. The air is still and the speed of sound is 340 m/s. What frequency will the pit crew member hear?...
Could someone show me where I am going wrong in this thermodynamics problem that I got marked wrong? 1 L•atm = 101.325 J A gas expands from 30 L to 50 L against a constant pressure of 1 atm. What is the calculated value for work in Joules? Report your answer in kJ to the nearest whole number. Ok so here is what I did: w = -PΔV w=(50-30)*-1 w=-20 L*atm =101.325*-20 =-2026.5 J =-2.0265 kJ which goes to -2...
I got 2/3 correct. Which one did I get wrong and please explain
