88 foot per second.
5280 feet = 1 mile
5280 × 60 = 316800
316800 feet per hour
3600 seconds = 1 hour
316800 feet per 3600 seconds
316800 ÷ 3600 = 88
88 feet per second
shes your teacher duh, they have magic spells that give em the answer

Answer:
1.02KPa
Explanation:
The following were obtained from the question:
V1 = 1550mL
P1 = 70.26kPa
T1 = 480°C = 480 + 273 = 753K
T2 = -237°C = - 237 + 273 = 36K
V2 = 5114mL
P2 =?
The final pressure can obtain as follows:
P1V1/T1 = P2V2/T2
(70.26x1550)/753 = (P2x5114)/36
Cross multiply to express in linear form as shown below:
P2 x 5114 x 753 = 70.26 x 1550 x 36
Divide both side by 5114 x 753
P2 = (70.26x1550x36)/(5114x753)
P2 = 1.02KPa
Therefore, the final pressure is 1.02KPa
Answer:
Chromatography is a method of separation of materials from a mixture. Paper chromatography is a technique of separation where, paper used as a stationary phase and solvent used to separate the sample used as a mobile phase. The sample is applied over the paper in small quantity. The components of the sample separates in a chromatographic paper due to the movement of solvent. The components of the sample moves with the solvent.
Paper chromatography is a useful technique for ink analysis. Ink consists of several dyes, which can be separated individually. When the ink is exposed to certain solvent mixtures the dyes of the ink dissolves in the mixture. Each ink components acquire distinct distance according to the retention factor. Some inks are water soluble, so the solvent used for separation should be water. Inks which are not water soluble are soluble in other solvents like alcohol.
