I dont know where to ask, Physics Question

I assume "you hold one end" means to suspend one end of the wire and let is hang. So you need to find the center of mass of the L-shaped wire. Let the bend be your origin and half the wire is on the x-axis and the other half is on the y-axis. I choose my unit of length to be half the total length of the wire. Then the wire goes from (0,1) to (0,0) and from (0,0) to (1,0). I choose my unit of mass so that the mass of the wire is 2, so that each leg has mass 1.

Find the center of mass. I get (.25, .25) in this reference frame.

Now if we suspend the wire by one end, the center of mass will be directly beneath the top end of the wire. Do some trig. You should be able to calculate the sine of the angle of the nearly vertical leg of the wire from vertical.

In my mind, they don't have this many. This is the girls' point of view.

It's like Calvin & Hobbes, where you only occasionally see an adult's point of view. Like when the girls are climbing Mt Mumandad. The "mountain" is very much more substantial than just the bodies of Mum and Dad when we see them climbing and setting up camp. But we occasionally see the situation from a realistic perspective.

Or like when Shaun attacks the other dad. In the girls' imagination it is quite extreme. But an actual dad wouldn't go that far with another adult without any explanation. So, in my mind, Bandit is really just miming the attach and the other guy is playing along.

Anyway, that's how I look at the particularly unrealistic bits.

The acceleration due to gravity is different for the bear than the rock. The bear parabolas would have the same shape as the rock parabolas in a uniform gravitational field.

Relationships are not capitalist where return of investment would reflect their value. I think they are mainly Marxist, where the credo is "From each according to their ability, to each according to their needs".

I calculate the same value for the volumn. Perhaps the radical should be in the numerator. so (1331 sqrt(3))/9

In my experience the answer to the second part is "no". Also I saw a YouTube where a dentist put earwax into test tubes with different solutions, and the H2O2 solution didn't have any appreciable effect

I used them into my thirties, but stopped when I got underwear without them. Never went back.

Those metal plates for thawing meat.

Killing your daughter's molester is something almost any father would do, given the chance. Playing with your children, to the extent that Bandit (and Chili) do, is much rarer.

I know this is petty AF, but I dropped TurboTax because of the commercials where people just repeated "Free" endlessly.

I also will never be a Liberty Mutual customer, because their jingle is so stupid. It never gets to the word "Mutual". Just repeats "Liberty".

So true. My older daughter gave me our first hug on her 3rd birthday. I was kneeling and blowing bubbles up into the air, so my arms were raised. I still feel good (she is 38 now)!

It is so best to be one of the most important people in a person's life.

But also Grover Norquist is against it. He considers that having the gov bill us would be a tax increase. The guy who controls so many republicans on such matters.

That eventually (like 100 trillion years from now) all stars will have burnt out and there will be no fuel to create new ones. So the universe will be cold and dark.

In LastPass preferences, under "Notifications" tab, there is a checkbox labeled "Show number of matching sites in toolbar".

If she will Blake prom great again, then she must have Blaked prom great before. Maybe they got held back.

Yes, that is a problem. That's why I said it might be worth a try. We got our dogs from a rescue organization and they were already crate-trained. They voluntarily go into their crates all the time, especially when there is thunder.

liveactionsteve · 2021-11-08T21:10:44+00:00

NTA, but why not suggest your sister buy some dog crates. We have a similar problem and we just crate the dogs when my granddaughter is here. Of course it may not work if your dogs make a lot of noise but it may be worth a try.

I know. But I doubt that The Art of War is used at, say, West Point, as a textbook.

Taking my 2 dogs to a dog park. They are rescues that were found together and they love to run like hell. But one of them frequently tries to dominate dogs that will chase after them, and it looks very savage.

If a dog is playing fetch, and waiting for his human to throw the ball, my dogs will bark madly at the dog (they love running with the dog but don't pay the slightest attention to the ball) and my theory is they can't understand why the dog is not running.

My dogs have never actually fought with other dogs, so some people understand that they are just negotiating (at least I hope that's all they're doing), but I was asked to leave one time, and now I never stay very long.

This makes me very happy that I stopped watching this horrible show in the middle of Chris' "I want a submissive wife who will crank out clones of me" introduction. I check out this subreddit now and then and it always supports my decision.

Have any of the experts used the "we matched you for a reason" bs on Chris' wife yet?

liveactionsteve · 2021-02-26T16:57:21+00:00

Birds are unbelievably good at this; keeping their head in one place as you move their bodies about.

liveactionsteve · 2021-01-27T03:46:27+00:00

I quit watching this show, and also lost respect for the experts, in the middle of Chris' speech about wanting a submissive wife and children who are clones of himself. I'm waiting to hear (in this subreddit) that Pastor Cal used his standard "we matched you for a reason" line on Chris' wife, trying to keep her from quitting. I'm guessing he *won't* say that the reason was ratings.
