Answer:
is the electron relaxation time
is the mean free path
Explanation:
Given:
- electron density of aluminium at room temperature,
- resistivity of aluminium,
<u>From the Drude's model we have:</u>
where:
electron relaxation time
mass of a charge
magnitude of a charge
Putting respective values for electron:
<u>Mean free path is given as:</u>
where:
mean free path
average velocity of electrons
- Now we have the the general value of average velocity of electrons at room temperature:
So,
Answer:
6.30 M⁻¹s⁻¹.
Explanation:
As the reaction is first order with respect to a and b.
<em>The rate of the reaction = k [a][b],</em>
where, k is the rate constant of the reaction.
The rate of the reaction = 2.65 × 10⁻⁴ M/s,
[a] = 1.60 × 10⁻² M,
[b] = 2.67 × 10⁻³ M.
∴ k = (the rate of the reaction / [a][b]) = (2.65 × 10⁻⁴ M/s) / (1.60 × 10⁻² M)( 2.67 × 10⁻³ M) = 6.30 M⁻¹s⁻¹.
10 mols platinum * 6.02*10^23 atoms = 6.02*10^23 atoms in platinum
Answer:
YES THE BULB WILL GLOW.
Explanation:
BECAUSE THE CIRCUIT UPPER AREA IS MADE OF PLASTIC SO THE PLASTIC CONDUCTS THE ELECTRICITY SO THE BULB WILL GLOW.
Because the salt water has salt in it causing to errade more
