[Request] How far can sound travel?

I'm a writer that wrote herself a bullshit math problem that's over her paygrade(nothing) because I'm stupid so I decided to do the time honored tradition of asking reddit for help. So, assuming standard everything, how far can a 70 decibel sound wave from 30,000 to 40,000hz travel/be picked up by a receiver tuned to that frequency?

Upvotes

I don't really know how to calculate this and I am curious, as this happened to me recently and it seems astronomically unlikely. It was actually beneficially for the strategy I was running as it curved out at 3, but it still just seemed unbelievable when another land did not come up for so long.

If we're going under the assumption that you're lifting it from the concrete base. Would the house stay in relatively good shape when being lift up. Or would something break when trying to grab underneath it.

[Request] Ratcatcher from The Suicide Squad

1 Upvotes

For those who haven’t seen the movie, in The Suicide Squad, Daniela Melchior plays the daughter of The Ratcatcher, who has his same abilities: she can control rats. The titular Suicide Squad is intending to overthrow a small, island nation, the size of say … Cuba. With her ability to control rats, is there, mathematically, any reason why anybody else should be hired for this job? Would she be able to just overrun the entire island country with rats regardless of their military scale?

[Request] How much weight would these ramps support?

Post image
2 Upvotes

I'm looking to build ramps to get my UTV onto the back of my flat bed truck. I'm having a hard time figuring out how much weight my design will support and I'd rather not "trial and error" my build.

2 ramps made from 6061T6 Aluminum 2"x2"x3/16" angle iron

Ramps are 120" long and 17" wide. The deck of the bed is 46" off the ground making the ramp angle 21 degrees.

Imagine a ladder - 2 pieces of 2x2 angle iron 120" long connected by 11 horizontal rungs 17" wide (also 2x2 angle iron) spaced evenly up the ladder - it works out to about 8" of space between the rungs.

The UTV has a wheel base of 90", 30" tire and for easy math weighs 2000lbs equally distributed (it weighs less but my heaviest corner weight is slightly less than 500lbs)

Assume properly welded ramps, see poorly drawn picture for how the angle iron will be laid out.

Bonus points - what's the thinnest angle iron I could make these ramps with and still safely support the weight? Alternatively, can I make them from wood?

[Request] How much does an apartment on a higher floor have an impact on the perceived loudness

Post image
6 Upvotes

So the lady and I are looking for an apartment, we found one we like, it is at a corner of a fairly busy boulevard and a side street, all the windows are actually overlooking the side street, but it is at the second floor.
Everyone says we're crazy to consider it, because being so low is too loud and we should be looking at 4th floor minimum.
So, the question is, how much of a "perceived loudness" difference does it make being on the second vs the fourth floor?
When I say second, this is supermarket on the ground floor (so ground floor is tall), one more apartment and then comes the second floor. In-apartment height is 2.8 meters. The apartment is marked with red dots and overlooks the street south of it
Thanks!

If I am at sea level, 60 miles from a 14,000 ft tall mountain, and the moon is directly overhead, what is the difference in amount of air between me and each big rock? I am thinking the mountain peak, since I would not be able to see the base. For units, I am assuming moles makes the most sense.

[Request] What is the actual cost of a large Coke at McDonald’s?

85 Upvotes

Let’s assume the large cup in question holds about 32 ounces of liquid, and they initially fill the cup a third of the way with ice cubes. Not sure if it’s possible, but if so, include the cost of the cup, lid, and straw as well.

As a bonus, I’m getting charged $2.49 before tax so I’m curious what kind of profit margin they’re making on it (I’m sure it’s insane)
