Mass and weight are two different things, this is correct. Weight is relative. For example, something with a certain mass will have a a different weight on the moon than on the earth. Although the mass does not change, the weight does. In this case, weight is relative to gravity.
Just my 2 cents, but if photons are massless particles, how can an increase in their concentration cause an increase in mass?
I would think the box would see an increase in pressure and temperature but not an increase in mass?
It's a little off topic, but I do know that drinking high pH (basic) liquids, or eating foods that have a high pH hampers the effectiveness of digestion. The pH difference neutralizes a portion of the stomaches acid and reduces the digestion of substances that rely on an acidic environment to be...
As I recall from biology, saliva works in the mouth and esophagus; but the pH of the stomache deactivates it from working further. I don't know which would be better; to drink during chewing or after chewing, but if I had to guess i'd say immediately after swallowing. Although I have no basis...
Saliva only aids in the digestion of food until it reaches the stomache. The amount of saliva produced would be more to do with the length of time the food was chewed for rather than if there was a presence of another liquid (although I'm just guessing). However, seeing how water is needed for...
Hello all, I'm new to the board here.
I have been scratching my head over an example in one of the books I was reading so I looked it up on google. I found an explanation differing from what i'd read, so I thought I would pose the question to this community and see what you think.
I have no...
