"Valence" electrons or the free electrons
<u>Explanation:</u>
Electrical conductivity can be defined as the property of the substance to conduct electricity, heat etc through it. This conductivity is caused due to the migration of particles which are electrically charged within the atomic lattice of the substance.
The outermost electrons or the electrons in valence shell are the main cause behind the conductivity property exhibited by any substance. Higher the number of electrons in outer shell, higher the conductivity.
Since these electrons are in the outermost shell, they can move easily. Under an impact of applied heat, charge these electrons migrate through the atomic lattice and thus conducts electricity, heat as the case may be.
Answer:
The answer is e.
Explanation:
We take:
Taking the gas as an ideal gas, we can use the ideal gas law:
⇒ 
⇒ 
Then:
⇒ 
Taking R=0.08205atmL/molK.
Answer:
Explanation:
Equation of the rocket is,
Here, v' is the relative velocity of rocket.
In space F is zero.
So,
Now the momentum can be obtained by multiply by m on both sides.
Now for maxima, 
Now,
Therefore, the mass of the rocket while having maximum momentum is 
By calculating the crests, you can find the waves' frequency.
Hope this helps!
