Answer:
1.94 x 10^-10 m
Explanation:
V = 40 V
The relation for the de broglie wavelength and teh potential difference is given by


λ = 1.94 Angstrom = 1.94 x 10^-10 m
Answer: 5) The second law of thermodynamics
Explanation:
According to the <u>second principle of thermodynamics:</u>
<em>"The amount of entropy in the universe tends to increase over time"</em>
So, in this context, entropy is a thermodynamic quantity defined as a criterion to predict the evolution or transformation of thermodynamic systems. In addition, it is used to measure the degree of organization of a system.
In other words: <u>Entropy is the measure of the disorder of a system</u> and is a function of state.
Answer:
25100A
Explanation:
t= 1ms = 0.001s
q = 25.1C
From the relationship between charge and current , the charge is equal to the product of current and time
q = i×t
Where q = charge
i = current
t = time
i = q/t = 25.1/0.001
i = 25100A.
That waves travel faster than the wave lenght!
