Answer:
The water molecule cannot escape, since the average velocity of the water molecules is less than one sixth of the escape velocity of venus.
Explanation:
The average speed of gas molecules is given by:
![v_{rms}=\sqrt{\frac{3RT}{M}}](https://tex.z-dn.net/?f=v_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3RT%7D%7BM%7D%7D)
R is the gas constant, T is the temperature and M the molar mass of the gas.
We know that a water molecule has a mass that is 18 times that of a hydrogen atom:
![M_H=1.01*10^{-3}\frac{kg}{mol}\\M_{H2O}=18M_H=0.02\frac{kg}{mol}](https://tex.z-dn.net/?f=M_H%3D1.01%2A10%5E%7B-3%7D%5Cfrac%7Bkg%7D%7Bmol%7D%5C%5CM_%7BH2O%7D%3D18M_H%3D0.02%5Cfrac%7Bkg%7D%7Bmol%7D)
So, we have:
![v_{rms}=\sqrt{\frac{3(8.314\frac{J}{mol \cdot K})740K}{0.02\frac{kg}{mol}}}\\v_{rms}=960.65\frac{m}{s}*\frac{1km}{1000m}=0.96\frac{km}{s}](https://tex.z-dn.net/?f=v_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3%288.314%5Cfrac%7BJ%7D%7Bmol%20%5Ccdot%20K%7D%29740K%7D%7B0.02%5Cfrac%7Bkg%7D%7Bmol%7D%7D%7D%5C%5Cv_%7Brms%7D%3D960.65%5Cfrac%7Bm%7D%7Bs%7D%2A%5Cfrac%7B1km%7D%7B1000m%7D%3D0.96%5Cfrac%7Bkm%7D%7Bs%7D)
The water molecule cannot escape, since the average velocity of the water molecules is less than one sixth of the escape velocity of venus:
![10\frac{km}{s}*\frac{1}{6}=1.6\frac{km}{s}\\0.96\frac{km}{s}](https://tex.z-dn.net/?f=10%5Cfrac%7Bkm%7D%7Bs%7D%2A%5Cfrac%7B1%7D%7B6%7D%3D1.6%5Cfrac%7Bkm%7D%7Bs%7D%5C%5C0.96%5Cfrac%7Bkm%7D%7Bs%7D%3C1.6%5Cfrac%7Bkm%7D%7Bs%7D)
Answer:
<u><em>1000 units for breakeven</em></u>
Explanation:
Let x be the number of units sold at breakeven.
The total sales at the point would be $2x.
Variable costs would be $1x and fixed costs are $1000.
Total costs are = $1x + $1000
At breakeven: Sales = Costs
Sales =m Costs
$2x = $1x + $1000
$1x = $1000
x = 1000 units.
At 1000 units the sales are equal to the costs ("breakeven").
<h2>Answer: It becomes an Ion
</h2>
When an atom has gained or lost electrons (negative charge), it becomes an ion.
In this sense:
<h2>I
ons are atoms that have <u>
gained or lost</u>
electrons in their electronic cortex.
</h2><h2>
</h2>
If a neutral atom <u>loses electrons</u>, it remains with an excess of positive charge and transforms into a positive ion or <u>cation</u>, whereas if a neutral atom <u>gains electrons</u>, it acquires an excess of negative charge and transforms into a negative ion or <u>anion</u>.
It is then how ions form bonds with other atoms differently depending on the number of electrons they have.
Mass of the displaced material. In water it would be the mass of the water that the volume of the ball displaces.
It’s hard to perfectly measure the distance something travels, as well as the exact time it takes, making the results have some variation.
