Answer
the concentration of electron/ volume (n) = 8.5 × 10²⁸ /m³
the drift velocity of electron
v = 2.615 × 10⁻⁴ m/s
time require is
t = 3231.35 s
I know what you are wondering and the answer is simply crystals are more dense than water , so they sink but if you warm it up they can combine with it to become one.
dose this help?
Answer:
Part a)
Part b)
So density of atmosphere at Martian Surface is very less than the density at Earth.
Explanation:
Part a)
As per ideal gas equation we know that
here we know that Martian atmosphere is equivalent to that of carbon
so we will have
now we will have
Part b)
Now for the earth surface the density of air is given for
so we will have
So density of atmosphere at Martian Surface is very less than the density at Earth.
Answer:
The value is
Explanation:
From the question we are told that
The temperature is
Generally the root mean square speed of the oxygen molecules is mathematically represented as
Here R is the gas constant with a value
M is the molar mass of oxygen molecule with value
So
=>
The sun’s huge mass gives it a strong gravitational pull. Because of this gravitational pull, planets that are closer to the sun tend to have different motion than planets that are further away from the sun, because the gravity becomes stronger the closer you get. I hope this helped!
