Probably the same as turning a bicycle.
Difference would be the bike has a front wheel, whereas the 'board has a rider, pushing the back of the board outwards, centrifugally.
It is not incorrect if used as a conversion factor ; but the OP specifically asked "Are we allowed to multiply like that"... then proceeded to not bother, or at least not show the bother.
My point is the OP used "reasoning" which, while useful in creating or validating a conversion factor, doesn't solve the equation by itself whereas, after including it in the calculation, simple cancellation does :
##100,000 \cancel t \times \frac{1,000kg}{\cancel t} = 100,000,000kg##
The Goa'uld were a good example of alien aliens : worms which serve as memory adjuncts ; somewhat similar to Star Trek's Trill symbiotes. And - as in many SF stories - could be commentary on the evils of persistent tradition/knowledge.
When the question says "10cm below the water level", does it mean 10cm below a(n imaginary) line drawn on the tube where the water level is before the oil is poured in ? or are we talking a consistent 10cm below the water level, regardless of whether there's oil on top, or not.
(ps: in your...

question : in Fig.7, one of the graphlines is uniform rods, which doesn't otherwise appear in the text. Theoretical calculation of the video's ladder ?

I don't recall that (read much Chalker many moons ago), but I'd nominate John Grisham.
Or, Spider Robinson : I swear the last 20 pages of almost every book, I'm thinking "Is this a two-parter?", then he segues into "and then they all got stoned, mind melded and saved the world". Sortof...
There's two people in this thread ; one of whom is not confused.
Repeat after me : "prolate cycloid"
Use the sliders : set r=1, d=6, hit play(bottom left corner)
Now, there's two.
You aren't confused ; just, apparently nobody bothered to think of using your example when they went about making diagrams. Every cycloid example you've seen is crap.
So, starting with this diagram...
we can see that for the common cycloid, the pen is on a point on the circumference of the...
It's not. In the aircraft reference-frame nothing changes : drag is a constant. If you wanted to "reverse" the cycloid to trace a circle in the ground reference-frame, yes, drag would vary.
---
Both ellipse and cycloid can be thought of as projections of a circle function.
Circle ...
Awesome !
The next two formulae are giving me problems...more cogitation required.
(Note that - on my screen, at least - all of them are cut off somewhere around the \implies's, which I didn't realize for awhile : tossed a couple extra $'s into the Quote to make it legible for myself.)
The problem looks pretty straightforwards (except maybe if you wanted numerical values for the BoxA<>BoxB force interaction, the value for friction [and mass] needs be specified for each box).
But, regardless of acceleration, the forces are still balanced when all the players are accounted for...
Whereas, treating it as an upward force does not... which is what I said.
But, the question does look unambiguously as if an upwards force is being applied, despite usage of "at" rather than "from" or "to".
If one were the applier of a downwards(ish) force, the obvious place to push would be...
That's also how I read it ...however the answer for that is not in the list.
It would have been so easy to phrase it like "A force of 300N is applied downwards, 30deg from the horizontal" or summat.
The soles were probaly polyurethane, which is nice and flexible for awhile but not 20 years. Some kind soul once gave me an old pair of otherwise decent workboots ... which lasted about 20 feet.
Meanwhile, narwhals don't have bacula : you're thinking walrus.
Apologies for insensitivity but the funniest part was the tire - not satisfied with causing the car to jump and flip ten feet in the air - comes around and hits it in the arse after it lands.
Just finished Jack Four(Asher) : the Prador are still the bad guys. There are timelines for his Polity Universe books, though ; give you the right order.
Lovable aliens ? ... Foster's Thranx I suppose (been quite awhile since I read those)... Weber's treecats... in that vein pretty much...
I'm trying to figure out how y'all get "laser" out of this. It isn't a stream of incompressible water. May want an adamantium or magical bell : particles are diverging from horizontal right at the portal.
True, in the limited sense of the natural numbers, which you did not specify in your original post, which had to do with motion, which measurement rarely approximates a natural number.
"zero" belongs in nature as much as any other number.
And, black holes certainly move : as well as evidence of galaxies (which commonly have huge BH's at their center) passing through each other, we've real-time observed black holes colliding.
