my apologies after i multiplied current x time i got 0.306, and then I divide by 1.6e-19? I want to make sure I get this right becausr I am running out my submissions, thank-you for ur time

yes... so its going to be current/time=charge and i got 8.5e-5 then i multiplied it by the charge on an electron 8.5e-5 x 1.6e-19 and I got 1.36e-23. Where am i going wrong?

i divided the current by 60 seconds... .0051/60 then i multiplied it by 1.6e-19 and i got 8.5e-5, but that is wrong what did i do?

I get 1.36e-5 for the charge. So is it going to be 1.36e-5/1.6e-19?

would i multiply 1.6e-19 C x 60 seconds? I have to use seconds correct?

Can anyone help me with this question? Thank-you A net charge of 51 mC passes through the cross-sectional area of a wire in 10.0 s. What is the current in the wire? How many electrons pass the cross-sectional area in 1.0 min? I know that the current is .0051, but I'm having trouble finding...

Can anyone help me with this question? thank-you An electron and a proton are each placed at rest in an external uniform electric field of 540 N/C. Calculate the speed of each particle after 46 ns. I changed the protons and electrons, I'm not sure why its just a step my instructor told us...

so where would 1.4 be incorporated? theta2=sin^-1(1.4/n2 sin45) ??i have two unknowns what would theta 2 be?? thank-you

Can anyone help me with these questions? They are due @ 10 p.m. tonight, thank-you. 1) A ray of light enters the top of a glass of water at an angle of 37° with the vertical. What is the angle between the refracted ray and the vertical? At first I thought I could just do 90-37, but that...

My mistake I got that one it is 3.05. But another where there frequency is 25 GHz. To find the wavelength on this one i would 3e8/25e9=0.012, and that is wrong. Thanx

Electromagnectic Wave Help Can anyone help me with this problem? What is the wavelength for an FM radio signal if the number on the dial reads 98.5 MHz? C=3e8 I know that c=f wavelength, and MHz is a million hertz I thought I could do 1E6 x 98.5=9.85e7 and then I could just solve for the...

Can anyone help me with this question? Thanx Calculate the frequency of the photon emitted when an electron in an atom changes from (-2.42e-19 joules) to (-21.76e-19 joules). I know that I'm going to use E=hf and h=6.63e-34. I'm not sure what I do with the 2 energy levels, do i...

Can anyone help me with these problems? they are really stressing me out, thanx 1) The arm of a crane is 20.0 m long and makes an angle of 25.0° with the horizontal. Assume that the maximum load for the crane is limited by the amount of torque the load produces around the base of the arm...

Can anyone help me with these problems? Thank-you 1.) In a circus performance, a large 4.0 kg hoop with a radius of 1.8 m rolls without slipping. If the hoop is given an angular speed of 5.0 rad/s while rolling on the horizontal and is allowed to roll up a ramp inclined at 12° with the...
