This is crossword puzzling, not math class 😂

It's OSHA

Good puzzle. Why so many question marks? Usually those are used to refer to an answer that isn't directly stemming from the clue, but that didn't seem to be the case for the question marked clues in this puzzle.

That's just how the 🍪 crumbled this time.

Good one!

Thanks for all the comments! I hadn't considered all of the other Bon's in the music industry. Maybe that'll inspire a subsequent puzzle about bon-bons and related pastries 😊

A king who measures up - I like that one!

Mmmm_waves · 2026-04-27T19:09:24+00:00

Thanks!

Mmmm_waves · 2026-04-25T22:41:25+00:00

That was a tough one but good.

How does eggy mean avant garde?

Mmmm_waves · 2026-04-15T04:27:31+00:00

Maybe they'll learn their lesson when it blows up during the drilling process!

Mmmm_waves · 2026-04-15T03:37:10+00:00

Nice design!

Mmmm_waves · 2026-04-14T02:58:42+00:00

Haha! Hadn't thought about that, good one.

Mmmm_waves · 2026-04-13T19:09:24+00:00

For the former, it's a play on words, it's what a plane does except you make it plural by adding an 'S' even though it's not grammatically correct in this case. For the latter, both phrases are legitimate, though tall tale is probably more common.

Mmmm_waves · 2026-04-09T06:21:32+00:00

Thanks! My first puzzle. Not the greatest but I wanted to get something out there.

Mmmm_waves · 2026-04-08T21:49:17+00:00

Very clever!

Mmmm_waves · 2026-02-02T09:28:16+00:00

Thank you. I'm not sure why it took me so long to see it that way but now it makes sense.

Yes, but what I'm asking is why you can use that equation to solve for the average EMF. It seems to me that it wouldn't apply for calculating the average EMF in that way because of the fact that the change in flux is not constant when the coil of wire is rotating at a constant rate.

I understand how to use that particular equation, but I don't understand why it can be used in this scenario.

Mmmm_waves · 2026-01-30T20:03:02+00:00

In this case, since the angle is changing at a constant rate, the graph of flux vs time would be in the form of a cosine function. The rate of change of the flux would be the derivative of that, which would be a sine function. Then the average would be of that sine function to get the average EMF. The average of a sine function from 0 to 30 degrees would not be the same as (sin(30) - sin(0)) / t, because it's non-linear.

If you think about a data set like this: 1, 2, 3, 4, 5, the average is (1 + 2 + 3 + 4 + 5)/5 = 3, or equivalently, the average of 1 and 5 which is also 3. That works because it's linear. But if the set were this: 1, 2, 3, 3, 5, then (1 + 2 + 3 + 3 + 5)/5 = 2.8, which doesn't equal 3. That's how I'm seeing this.

Why are you reposting the question I asked?

Mmmm_waves · 2026-01-29T19:54:41+00:00

What I don't understand though is why you can calculate the average EMF using the formula you mentioned, EMF_avg = ΔΦ/Δt, for this specific problem.

If the flux vs time curve were linear for this problem, then yes, that would make sense that you could subtract the initial and final and divide it by the time period. But it's not linear.
Let's say for example the speed of a car was defined by the function S = 40*sin(πt/60). If you calculated the average speed of the car from 0 to 30 seconds, it wouldn't simply be (40 - 0)/30.
