Single axis means they trace one arc across the sky. The sun traces a different arc every day. I'd presume that the optimal arc for...

Why is there lower power in the middle of the day? I thought they oriented at the optimal angle at all times. How can you do better than...

Yup. Often the first question the plumber will ask is do you know where the clean out is located.

I think engineers have figured this out, and the results are obvious if you just look at the way solar panels are designed and...

The issue with the OP was that he was using the wrong "r"(or, rather, mixing and matching). The radius of curvature of the panels for a...

Well, if you ever do have a clog finding the clean out will be the plumber's problem. Years ago a plumber just dug a hole, broke the...

Can't tell from photo. Can you see it from inside the attic? Does it come straight up through the wall below. If you can determine...

When I was a practicing EE, none of this ever made sense to me. These problems rarely mention the probability distribution of the data...

Agreed. When rounding off to the so-called appropriate number of sig figs what you are really saying is "Don't worry about the...

That is the issue, so the "correct" answer is a result of however well the instructor or textbook authors understand the issue. The...

Part of the problem is that there are two common systems which many (most) conflate. Either imply the uncertainty from the number of...

If that's the convention used in your class then that's what you do. That is confusing, but when expressing a result in the form ##x...

Either of these are good choices, but I would start with something simpler. Paul G. Hewitt's approach is my favorite. He states that at...

Certainly you cannot find a numerical value, but we do know that ##v_{max}=\dfrac{a_o}{k}## where ##a_o## and ##k## are given in the...

The energy of a photon is inversely proportional to the wavelength. Hence $$\frac{E'-E}{E} = \frac{E'}{E}-1 = \frac{\lambda}{\lambda'}...
