Answer:
Cat and a dog
Explanation:
The cat might bark instead of meow because it has certain traits from the dog. The dog however may still bark because it is a dog!
Volume=mass/density
volume=455.6/19.3
volume=23.6 mL
Static Friction
It is the friction that exists between a stationary object and the surface on which it's resting.
Sliding friction
It is the resistance created by two objects sliding against each other.
Rolling friction:-
It is the force resisting the motion when a body rolls on a surface.
hope this helps x
Answer:
![m=1864.68\ g](https://tex.z-dn.net/?f=m%3D1864.68%5C%20g)
Explanation:
Given:
volume of air in the room, ![V=410\ m^3](https://tex.z-dn.net/?f=V%3D410%5C%20m%5E3)
temperature of the room, ![T=25+273=298\ K](https://tex.z-dn.net/?f=T%3D25%2B273%3D298%5C%20K)
<u>Saturation water vapor pressure at any temperature T K is given as:</u>
<u />
<u />
putting T=298 K we have
![p_{sw}=3130\ Pa](https://tex.z-dn.net/?f=p_%7Bsw%7D%3D3130%5C%20Pa)
<u>The no. of moles of water molecules that this volume of air can hold is:</u>
Using Ideal gas law,
![P.V=n.R.T](https://tex.z-dn.net/?f=P.V%3Dn.R.T)
![n=\frac{P_{sw}.V}{R.T}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7BP_%7Bsw%7D.V%7D%7BR.T%7D)
![n=\frac{3130\times 410}{8.314\times 298}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B3130%5Ctimes%20410%7D%7B8.314%5Ctimes%20298%7D)
is the maximum capacity of the given volume of air to hold the moisture.
Currently we have 80% of n, so the mass of 20% of n:
![m=(20\%\ of\ n)\times M}](https://tex.z-dn.net/?f=m%3D%2820%5C%25%5C%20of%5C%20n%29%5Ctimes%20M%7D)
where;
M= molecular mass of water
![m=0.2\times 518\times 18](https://tex.z-dn.net/?f=m%3D0.2%5Ctimes%20518%5Ctimes%2018)
is the mass of water that can vaporize further.
