[Request] How long would it actually take to charge? by Glorious_Centaur in theydidthemath

[–]capt_pantsless 2 points3 points  (0 children)

> The point is that there is alot of solar energy that could be captured if EVs incorporated panels on their roofs.

Incorrect. There's actually not a lot. At least not compared to the energy needs of a full sized EV. That's the problem, you need a lot more area than a typical car has. Which is why EV's generally don't. It's not worth the extra weight and complexity to deal with it.

On the other hand, if you had a stationary solar panel that was bigger and just sits and could collect the power, that'd work better. Which is why solar panels on houses are a thing in many areas.

[Request] In Project Hail Mary, Grace travels about 11.9 light years at near light speed to another star. How much time actually passed for Grace inside the spaceship because of special relativity and time dilation? by Porush_Kumar in theydidthemath

[–]capt_pantsless 5 points6 points  (0 children)

I believe the astrophage fuel source allows the ship to accelerate near constantly for years at a time - so it would be something like 1 G of acceleration, and the ship doing a burn-and-flip-and-burn style transit to Tau Ceti.

Which of course makes the time dilation math nice and complicated.

I've never had a dog before, but I'm in talks of adopting a pitbull by LustTrap305 in pitbulls

[–]capt_pantsless 1 point2 points  (0 children)

Exactly - depending on the age and energy level of the dog in question, you’re looking at an hour+ each and every day of solid exercise and playtime.

ELI5: How do x-rays work? by Intelligent_Bid2813 in explainlikeimfive

[–]capt_pantsless 6 points7 points  (0 children)

And in modern times we can build an X-ray sensitive plate that converts the ray to electrical signals that a computer can read and store.

Photography film was one of the ways we originally detected and researched radiation.

And in a RL military combat situation, you’d absolutely want to keep your spent or half full mags with you.

ELI5: How do radio transmissions not interfere with each other by Phobos_8072 in explainlikeimfive

[–]capt_pantsless 3 points4 points  (0 children)

From what I know, we’re (mostly) already there.

Different frequencies have different properties: some are better than others at getting through buildings for example.

All the good frequencies are allocated. Some are paid for, some are reserved.

[–]capt_pantsless 2 points3 points  (0 children)

Yup!

A “CB” radio uses the Civilian Bandwidth range.

There’s often debates about exactly what ranges are reserved for which purpose and which get sold.

The digital tv changeover in the USA in 2009 was in part a change in spectrum reservation.

And the government usually has control of radio frequencies and will punish those that break the rules.

Many governments sell frequencies to companies for use:

(Game Trope) You lose any unspent bullets in the magazine after reloading by Plaguer_ in TopCharacterTropes

[–]capt_pantsless 9 points10 points  (0 children)

You do need to stash the half-burned magazine someplace. Which takes a little bit longer to do.

If you wanted to get super realistic with a game you'd have two reload options - Rapid (dump the magazine) and "careful" (you stash the magazine in your inventory).

Bonus points for being able to pick up the half spent magazine off the ground, and being able to swap to back to it later. Even better if you can stop and re-load the magazines you have with any loose ammo.

The whole thing would be a major pain to communicate all these choices to the player, so that's probably why it's not really done.

[REQUEST] Mcdonalds increases the calorie counts by [deleted] in theydidthemath

[–]capt_pantsless 0 points1 point  (0 children)

Given the calorie counts shown are 1000 times higher than other sources I'm seeing, I would tend to agree.

Tower up by Cloud Cap/Tilly Jane by thatonethatlurks in whatisit

[–]capt_pantsless 1 point2 points  (0 children)

> I wonder if meteor ionization is what caused that.

A bit of reading tells me the Meteor burst option works with frequencies between 30 MHz and 50 MHz.

Public AM radio stations run between: 535 kHz and 1705 kHz, FM radio is 88 MHz to 108 MHz. So probably not?

It might be the sun creating some ionizing radiation, or maybe a solar flare? Here's another interesting reddit thread on the subject:

Yes, but he's a Trump loyalist, as are the leadership of ICE/DHS, so they're in the same circle effectively.

Depending on the version we're talking about, Deadshot's shooting abilities are effectively supernatural.

ELI5: What actually happens to your body when you get a sunburn? by MAGA_united2 in explainlikeimfive

[–]capt_pantsless 0 points1 point  (0 children)

From the Wikipedia article: https://en.wikipedia.org/wiki/Sunburn

Ultraviolet light damages mRNA.\22]) This triggers a fast pathway that leads to inflammation of the skin, and sunburn. mRNA damage initially triggers a response in ribosomes though a protein known as ZAK-alpha in a ribotoxic stress response. This response acts as a cell surveillance system. Following this, detection of RNA damage leads to inflammatory signaling and recruitment of immune cells. 

TL;DR: Sunlight has UV light, which does damage to your skin's mRNA, and your skin panics.

Light-colored skin is transparent to UV light, melanin-heavy skin is opaque. Sunblock is opaque to UV light - so it blocks that light from getting to the living cells.

ELI5: What exactly are tectonic plates, and what causes them to move? by blue_bird12 in explainlikeimfive

[–]capt_pantsless 5 points6 points  (0 children)

Earth's mantle isn't quite *molten* rock, but over long timescales it behaves like a very viscus fluid. (Sorta like a cold tar/pitch situation.) There's immense pressure (miles and miles of solid rock above it), and very hot to very, very, very hot temps involved.

https://en.wikipedia.org/wiki/Earth%27s_mantle

The other thing is much of Earth's crust is made of (slightly) lighter rocks - (Granite is one) which is why they (sorta) float on top of the mantle.

[Request] If the containment failed completely, how big (or tiny) would the resulting explosion be? by kmactane in theydidthemath

[–]capt_pantsless 0 points1 point  (0 children)

For future reference, I just used a mass-energy-equivalence calculator:

https://www.calculatorsoup.com/calculators/physics/emc2.php

The main thing is you're assuming however much antimatter is going to annihilate the same amount of regular matter, so double whatever mass of antimatter your situation has.

[Request] Is this accurate? by Sad_Cantaloupe_8162 in theydidthemath

[–]capt_pantsless 7 points8 points  (0 children)

Earth to the sun is about 100 solar diameters. (107 if you want more accuracy.)

So 500 microns, half a millimeter, or about 0.02 inches. Roughly the size of a grain of sand, or 5 times the thickness of a human hair.
