Volts is the electric potential while Watts is rate of energy

Volts is measured in joules per Coulomb

What post?

Notes from the class

Am I correct?

Homework Statement How many volts is required for a tiny spark to be created in electrostatics? Homework Equations No equations The Attempt at a Solution 5,000 watts

Oh yeah wavelength, so is λ=4L/n λ=4(.08)/7 Since is 7th harmonic. λ= .045m

Wavelength

Okay, I guess that's the correct answer. But Thank you sir for your help

f= f(v-o/v-s) I got 1036.64Hz

Homework Statement What is the wavelength of an 8cm closed pipe when it is sounding the 7th harmonic? Homework Equations L=λn/4 The Attempt at a Solution L=(.08m*7)/(4) L=0.14m Am I correct?

Forget this question, can you please delete this thread?

Frequency of Siren is 988Hz

So what's the correct formula?
