The electron relaxation time is
The mean free path is
<u>Explanation:</u>
Electron density,
Aluminium resistivity,
From the Drude's model we have:
Where:
τ= Electron relaxation time
m = mass of a charge
q = magnitude of a charge
We know, electron mass =
Charge of electron =
By substituting all given values for electron, we get
When multiply by 100 and divide by 100, we get
Mean free path is given as:
where:
l = Mean free path
= Average velocity of electrons
We know the general value for average velocity of electrons at room temperature:
Therefore,
Answer:
Earth's mass is 5.98 x 1024 kg and has a radius of 6.37 x 106 m. 8.06 N/kg ... what would be the weight of a 70.0-kg student on the surface of Jupiter?Explanation:
We can get water from the sweat and exhaled breath of the people present in the space station.
<h3>How would you get water?</h3>
We can get water from the sweat and exhaled breath. The water we drink is recycled from the sweat and exhaled breath of the people present in the space station which was collected through condensation on the Space Station's walls.
So we can conclude we can get water from the sweat and exhaled breath of the people present in the space station.

The doppler effect. as it gets closer the frequency increases and gets louder
PV/T =C
P.V1/T = 1/2P.V2/3/4T
V1= 4V2/6
V2/V1 = 6/4 =3/2
