C and A the first one is a bit weird but thats what i got and you cant even see it that good
Use the Ideal Gas Law to the air in the tire :
( P ) ( V ) = ( n ) ( R ) ( T )
n = ( P ) ( V ) / ( R ) ( T )
P = P gauge + P baro = 31.2 psig + 14.8 psia = 46 psia
P = ( 46 psia ) ( 1 atm / 14.696 psia ) = 3.13 atm
n = ( P ) ( V ) / ( R ) ( T )
n = ( 3.13 atm ) ( 4.6 L ) / ( 0.08206 atm - L / mol - K ) ( 26.0 + 273.2 K )
n = 0.5864 moles
m = ( n ) ( M )
m = ( 0.5864 mol ) ( 28.96 g/ mol ) = 16.98 g
The answer is A study of different surfaces to compare ability to repel water. Hope this helps!
Answer:
1. A solid can diffuse into a liquid, but a solid cannot diffuse into another solid.
3. A liquid can diffuse into another liquid.
4. A gas can diffuse into another gas.
Explanation:
When an object is in liquid or gas form, they can easily move and spread. This is because the molecules are packed loosely. Since they can move freely, diffusion on and into gas/liquid can be easily achieved.
Solid form can diffuse into liquid too. Seawater is mostly made of water and solid salt. But diffusing a solid into a solid is not possible since the molecule is tightly packed and barely moves. The diffusion might be happening, but at a really slow rate that we can assume it is not.
Answer: two way gravity is affected if somethings weight is doubled or grtavity gets weaker with distance
