Answer : I = 0.0906 A.
Explanation :
It is given that,
No of electrons flowing in a wire,
We know that the charge on an electron is given by,
So the total charge becomes:
We know that the current in wire is defined as,
Hence, this is the required solution.
Answer: 4
Explanation: when you're solving velocity you should divide the two numbers so 16/4=4
The arrows at the side would be compression, and the arrow pointing down should be labeled tension :)
Answer:
The energy becomes 4 times greater.
Explanation:
We know that the energy of a wave is proportional to the square of its amplitude
E ∝ Amplitude^2
Since the original amplitude = 0.5 m
and the new amplitude becomes = 1 m
We are doubling the amplitude. This means that the new energy will be affected by a factor of 4
E_new ∝ (2*Amplitude)^2 =
E_new ∝ 4*(Amplitude)^2
E_new = 4*E
