What's wrong with this setup is the substrate on which you have positioned
the drop is "dirty and unclean" meaning it is not being dampened by
the solution. This action can be corrected by comprehensively cleaning the
substrate where the drop will be positioned.
We have to convert 0.18 km into feet
First, we need to know the conversions:
1 inch = 2.54 cm (exact)
1 pound = 454 g
1 Liter = 1.0b quarts
1 feet = 12 inches
1 galion = 4 quarts
1 pound = 16 ounces
0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft
Answer: 590 ft (2 significant figures)
Answer: People that are usually nearsighted have lots of difficulty reading road signs from far distance, also have difficulty with seeing distant objects clearly, and this is obviously something dangerous for a person who has trouble with seeing from far. And the weird thing is, they might have that difficulty but in the other hand, they are able to see very well from close-up tasks such as reading a book or seeing the computer screen clearly. This disability is called "myopia". In addition, people who are nearsighted also have difficulty seeing objects from far distance very blurry. Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak.
I hope this helps answer your question! If you have options for this question, let me know k :) (Ask for help too)
Answer:
2.73 is the equilibrium constant for the dissociation of 
gas at 840 degree Celsius.
Explanation:
Initial
0.600 atm 0
Equilibrium
(0.600 atm - p) 2p
Total pressure at equilibrium = P = 0.984 atm
P= 0.600 atm - p)+2p=0.984 atm
p = 0.384 atm
Partial pressure of the gas , 
= (0.600 atm - 0.384 atm)=0.216 atm
Partial pressure of the 
gas, 
= 2(0.384 atm)=0.768 atm
2.73 is the equilibrium constant for the dissociation of gas at 840 degree Celsius.
