Yeah, but unfortunately it has to protrude from the surface because the bit grabs the outside, which means you can also grab it with pliers. Not the best feature for a “security” fastener.

No worries, no big deal

R^2 is on the bottom.

That nifty gravitational law gives you the force of gravity on an object, not the acceleration. Force also equals mass times the resultant acceleration, right? So Fg1 = m1A1 = GMm1/r^2 and Fg2 = m2A2 = GMm2/r^2. m1 and m2 are present on both sides of those equations, respectively, so they cancel, and you get A1 = GM/r^2 and A2 = GM/r^2, which are identical. The mass of an object affects the force of gravity, but when you look at acceleration the mass terms cancel out.

They would have the same coefficient of drag, correct, but the air resistance would end up having more effect on the lighter mass of the hollow sphere, so it would be slightly slower to fall.

Archimedes principle here is accounted for in the different weights. Everything that you can put on a scale is already being acted on by Archimedes principle in air.

Why don’t you think taxing the super rich is great?

Hasan has never said not to vote blue in the general election, he encouraged people to vote for Biden and Harris in 2020/2024

The sitting president just did an ad for them in front of the white house. It might rise a little from that, but I would expect the larger downward trend to continue because of the growing anti-Musk sentiment across the country.

I’m even later getting around to reading this, but thanks for the suggestions!

Not that anything he does is legal, just that he can’t be held personally legally responsible for it after leaving office.

I share your concerns, but the supreme court hasn’t said the president can do anything he wants (yet).

People in warmer countries are better prepared for the heat. When it snows in New England nobody dies, but when there’s a dusting in Texas all hell breaks loose.
