Answer:
-the ratio of the speed of light
in air to the speed of light in the substance.
-speed of light in air 300,000 km/sec, which decreases when it passes through a transparent substance.
-e.g.. speed of light in substance = 200,000 km/sec, R.I. = 300,000/200,000 = 1.5
Explanation:
Answer:
0.3
Explanation:
V = I R
1.5= I (50)
I = 1.5/50
I = 0.3 J
Therefore, 0.3joule current flows through the circuit.
