Answer:
P₁ = 192 W and P₂ = 384 W
Explanation:
It is given that,
Resistor 1,
Resistor 2,
Voltage, V = 48 V
Power dissipated by resistor 1 is given by :
P₁ = 192 watts
Power dissipated by resistor 2 is given by :
P₂ = 384 watts
So, the power dissipated by both the resistors is 192 watts and 384 watts respectively. Hence, this is the required solution.

Answer:
The wavelength of the electron is
Explanation:
Given that,
Temperature = 300 K
We know that,
The energy of free electron is
Where, k = wave number
The momentum of the electron is
Th effective mass is
We need to calculate the wavelength of the electron
Using formula of wave number
Put the value of k
We know that,
Thermal energy of electron
The de Broglie wavelength of the electron is
Put the value into the formula
Hence, The wavelength of the electron is
<span>Metals have a large number of free outer electrons that allow for
the movement of electrons through them. Just a hint of voltage
along a piece of metal is enough to persuade some of the free
electrons to move in the direction of increasing voltage. </span>
"Impulse" is (force applied) x (time that the force lasts) .
[Force] x [time] units are [Newton] x [second] .
If you go a little farther, it turns out that 'impulse' directly
produces a change in momentum, so it should have the
same units as momentum ... [mass] x [speed] .
In fact, it does ! But I doubt that you want me to go into that
right now, since you really didn't ask about it. So you'll just
have to take my word for it: Impulse and momentum both have
the same units.
