the given dimensions + expansion value.

My answer from that comes out to be 2.36 but I don't know how to find the minimum spacing piece that you're talking about.

I did not change to degrees Celsius. The conversion is (5/9)*(150-32) so my new temp is 65.556. Also, I have to change cm -> mm. so the dimension would be 4000 mm. So, my final equation would be (9e-6)(4000)(65.556) ??

Given: The linear expansion coefficient of glass is 9 × 10−6 (◦C)−1. An automobile windshield has dimensions of 60 cm by 400 cm. What minimum spacing around the wind-shield is needed to prevent the windshield from breaking if the temperature changes by 150◦F? Answer in units of mm. I...

Well, the question says "A 20 V battery delivers 107 mA of current when connected to a 74 ohm resistor. Determine the internal resistance of the battery."

How can I go about calculating internal resistance? I have variables I, R, and V but no idea on how to find the 'internal' resistance. Is this some sort of special case?

If given variables A, d, V, and constant 8.854e-12. How can I find the magnitude of surface charge density. I originally used Sigma = Q/A but I am not getting the right answer. Any help is appreciated! :)

so just 1.24 m x (6.33 x 10 ^5)?

So, there is no integration involved, just multiplication?

After reading it, I still don't know how to get to the correct equation, whether it's just plug-and-chug or if I have to integrate.

Even though an electric field doesn't actually "flow," I think of it as the flow of electric field vectors, either inward or outward.

A 124 cm diameter loop is rotated in a uniform electric field until the position of the maximum electric flux is found. The flux in this position is measured to be 6.33 x 105. What is the electric field strength?

Wow...you were all right; much simpler than I ever thought it was. Thanks to all of you for putting up with my stupidity for the time being. I am sure I will need more help soon and down the road [next week probably :) ] and I would be glad to get your guys help again. Thanks again!
