Answer:
R = 5.20 Ω, L = 6.24 10⁻⁴ H
Explanation:
The current in an RL circuit is
I = 
τ = L / R
In the problem they indicate the value of the voltage, the current and the time constant, for which the resistance must be found
The stable current is when enough time has passed (t »τ) after closing the circuit, therefore the exponential term is very small and we can neglect it.
I = E / R
R = E / I
let's calculate
R = 13.0 / 2.50
R = 5.20 Ω
now with this value we can find the inductance of the coil
τ = L / R
L = τ R
L = 1.20 10⁻⁴ 5.2
L = 6.24 10⁻⁴ H

Answer:
Its a parallel connection
Explanation:
The bulbs aren't in one line but two different parts, which makes it a parallel connection instead of a series connection.
Answer:
Statement 2 is wrong
Explanation:
To check the statements in this exercise, let's describe the main properties of electromagnetic waves. Let's describe the characteristics
* they are transverse waves
* formed by the oscillations of the electric and magnetic fields
* the speed of the wave is the speed of light
with these concepts let's review the final statements
1) True. Formed by the oscillation of the two fields
2) False. They are transverse waves
3) True. Can travel by vacuum as they are supported by oscillations of the electric and magnetic fields
4) True. They all have the same speed of light
Statement 2 is wrong
