Answer:
d = 5.75m
Explanation:
Using snell's law, we have,
n₁ × sin(i) = n₂ × 2 × sin(r)
n1= refractive index of 1st medium= 1
n2= refractive index of 2nd medium = 1.33
r= angle of reflection
therefore,
Here,
i = 90 - θ
Therefore, the distance is
d = 3 + d₁
d = 3 + 2.75
d = 5.75m
Answer:
I = 16amp
Explanation:
Charge coulomb ( Q ) = It
Where I =current in ampere
t = time = 5 seconds
80 = I × 5
I = 80/5
I = 16amp
The current through the circuit will be I = 16amp
