Answer:
E = 10t^2e^-10t Joules
Explanation:
Given that the current through a 0.2-H inductor is i(t) = 10te–5t A.
The energy E stored in the inductor can be expressed as
E = 1/2Ll^2
Substitutes the inductor L and the current I into the formula
E = 1/2 × 0.2 × ( 10te^-5t )^2
E = 0.1 × 100t^2e^-10t
E = 10t^2e^-10t Joules
Therefore, the energy stored in the inductor is 10t^2e^-10t Joules
Answer:
no because its a elctromagnetic wave
Explanation:
Answer : [tex]v = 59.02\ km/s[/tex]
Explanation : given that,
Arm length = 8.50 meters
Wavelength = 658 nm
Number of fringe = 1
We know that,
Formula of the speed is
Now, put the values
Hence, this is the required solution.
