Do sealed, airtight goods generally appear more inflated in Denver than (say) Miami because of the difference in pressure, or is the effect too small to notice?

If changing direction is considered acceleration, how does light not accelerate when bending in a gravitational field?

Light travels at a constant speed and that cant change, so how does this work?

What is the rate of energy transfer through tidal friction?

Posted: 25 Jul 2016 07:16 AM PDT

The Moon 'drags' the oceans around the Earth which transfers kinetic energy from the moon to the earth in the form of heat through the friction. What is the power (energy per unit time) associated with this effect?

How do silent heart attacks work?

Posted: 25 Jul 2016 04:54 AM PDT

Many people have had heart attacks with little or no symptoms and then continued on with their lives, none the wiser. My question is, how does this work? By that I mean, if the vessel is blocked and the heart muscle is dying, why does the heart attack not continue until they die? Is it that there is enough blood for some but not all of the tissue so part of it dies and the rest then lives?

why is coulombs law inaccurate for experiments done with small separation distances?

Posted: 24 Jul 2016 06:54 PM PDT

as the title states, I'm not sure why a small separation distance would affect the accuracy of coulombs law. Is it not accurate no matter the distance of the point charges?

I thought this might be a fun question to hear what everyone has to say. Also, first post on this subreddit! :)

How does an expectorant work? specifically ginger and honey?

What actually happens in the body that makes ginger and honey expectorants? Why does this work?

Can light be deflected by light?

Posted: 24 Jul 2016 12:47 PM PDT

I was initially thinking about lightsabers deflecting lasers in star wars but wondered if it's even feasible.

How do antivirus software scan password-protected archives?

Posted: 24 Jul 2016 10:09 AM PDT

If a compressed archive is encrypted with a password (.zip, .rar, .7zip etc), it is inaccessible. But how does antivirus software gain access to it regardless to scan it?

Edit: Thank you for the answers everyone!

Why the body temperature of chickens is so close to the temperature of denaturation of proteins?

Posted: 24 Jul 2016 09:52 AM PDT

The melting temperature varies for different proteins, but temperatures above 41°C (105.8°F) will break the interactions in many proteins and denature them. This temperature is not that much higher than normal body temperature (37°C or 98.6°F), so this fact demonstrates how dangerous a high fever can be.

The internal body temperature of birds shows more variability than mammals, and therefore there is no absolute body temperature. In the adult chicken the variability is between 105°F and 107°F (40.6° and 41.7°C).

Is there a something special about chickens and their proteins? Are they denaturate at higher temperatures?
