@aadityav, to clarify your teacher’s intent, you could ask them this: Planet A has a surface gravitational field strength of 51...

There is another way of looking at this. First let's ask why the pilot loses consciousness. I would say that if he accelerates up with...

The professor is still wrong. Let us grant that the intended threshold for pilot unconsciousness is 6g of coordinate acceleration. This...

The question is a bit of a trick question. It says the maximum upward acceleration is 6g. The correct answer is given by...

Welcome! Please, see: https://en.wikipedia.org/wiki/G-force#Vertical The pilot loses consciousness whenever the force with which his...

Just tried to answer your questions: Why is the angular acceleration anticlockwise here, against the direction of angular speed...

Please, note that the value of the final angular velocity is 20t=24 rad/s. The dynamic friction of the rotating-sliding cylinder with...

Expanding the original problem to be an ## nx1## rectangle, it turns out the angle B to add to angle A (defined by the ratio...

Rollback it is. https://arstechnica.com/space/2026/02/nasa-says-it-needs-to-haul-the-artemis-ii-rocket-back-to-the-hangar-for-repairs/

Doesn't look so good for Artemis. This is something they discovered after the WDR. If they roll it back, we are looking at the April...

It can be shown that the yellow figure of the last graphic in post #8 can be completely contained in the blue figure. Take off an...

The equation ## C=A+B ## is actually Euler's formula $$ \arctan\frac12+\arctan\frac13=\frac\pi4 $$, and there are three more formulas of...

Google AI mode: "how does the fomoco gk2a-6c624-bb oil level sensor work?" "The Fomoco GK2A-6C624-BB oil level sensor works using...

Here is another way but it’s just a variation of @coquelicot above in post #7 but the lengths are not obvious so they must be...

The heating could be induced by the thread profiles of screws and nuts not perfectly matching, as when new. If that is the case...
