Im not sure how to convert T into Wb. I tried to look it up on google and the only thing i found was T=Wb/m^2. But i am not given m^2.

Homework Statement A solenoid 1.7 cm in diameter and 30 cm in length has 4000 turns and carries a current of 5 A. Calculate the magnetic flux(in Wb) through the circular cross-sectional area of the solenoid. Since this is a very long solenoid, you may use the simplified magnetic field formula...

In class we used a voltmeter to measure the voltage across the different parts of a circuit. In the circuit there was a battery, resistor and light bulb. they just had us measure in parallel using the voltmeter all the parts including the wire. One of our questions afterwards was why are some of...

Why are voltages across a wire in a circuit zero?

Homework Statement Why are voltages across wire close to zero? Or is it just a coincidence? Homework Equations The Attempt at a Solution

Ok, thank you so much!

The reason i used 1.6x10^-6 is because it is supposed to say 1.6 micrograms. the symbol didnt paste with the rest of the problem. sorry about that.

I attempted questions a and b from my question i posted but when i put it into my online homework it says its incorrect. I wasnt sure what i was doing wrong.

Homework Statement A small piece of dust of mass m = 1.6 g travels horizontally through an electric air cleaner in which the electric field is 508 N/C. The electric force on the particle is equal to the weight of the particle. a)What is the charge on the dust particle? b)If this charge is...
