Thanks - so the value of t is the Earth clock and I am solving for to. I get a value of .00848 seconds. This value makes more sense from what I have read.

Any help here? Does this look correct or am I off base with the equation that I am using?

A firecracker goes off in Houston, Texas. A time 0.0133 seconds later as measured by synchronized Earth clocks, another firecracker goes off in Great Falls, Montana 2400 km away as measured on earth. a. How fast must a rocket ship travel if it is to be present at both events? b. What will...

Homework Statement A 15-mm-thick layer of water (n = 1.33) floats on a 60-mm-thick layer of carbon tetrachloride (n = 1.46) in a tank. A penny lies at the bottom of the tank. At what depth below the top water surface do you perceive the penny? (Hint: Use the result and assumptions of Problem...

So what is the difference between finding the electric potential of the nucleus and of the atom? any help here?

Homework Statement (a)the electric potential established by the nucleus of a hydrogen atom at the average distance of the circulating electron (r = 5.29 multiplied by 10-11 m) I solved this part using V = kq/r and got 27.2249V (b) the electric potential energy of the atom when the electron...

Okay - let's go back to the begining, because I am messing up somewhere: C1 = 11microF C2 = 7microF C3 = 3microF Voltage across arrangement = 100V --------------------- C123 = C12 + C3 C12 = 1/(1/C1+1/C2) | | |...

The charge is the same - the voltage across wach capacitor will differ

Ok- so I solved for 1/c1 + 1/c2 = 233766.2338, plugged that into Q/V = 1/(1/Ceq) = 4.277e-4 to get the charge, is this charge on both capacitors or is it split over both.

No-the only thing I can figure is that I needed to find the capacitance of 1 and 2 together because they are in a series. I thought I did this by C12=Q/V = 1/c1 + 1/c2. With this combine capacitance I can then find the charge.

1. Homework Statement a potential difference V = 100 V is applied across a capacitor arrangement with capacitances C1 = 11.0 µF, C2 = 7.00 µF, and C3 = 3.00 µF. Find the following values Charge on each capacitor, potential difference on each capacitor, and stored energy in Joules. The circuit...

wow - thanks - I knew there was something obvious I was over looking

Space vehicles traveling through Earth's radiation belts can intercept a significant number of electrons. The resulting charge buildup can damage electronic components and disrupt operations. Suppose a spherical metallic satellite 0.9 m in diameter accumulates 2.2 µC of charge in one orbital...

Homework Statement The charges and coordinates of two charged particles held fixed in an xy plane are q1 = +3.5 µC, x1 = 1.5 cm, y1 = 0.50 cm, and q2 = -4.0 µC, x2 = -2.0 cm, y2 = 1.5 cm. (a) Find the magnitude of the electrostatic force on q2. Done I got this part = 94.98868N (b) Find the...
