Answer:
4.38 × 10⁻³ A
0.395mΩ
452 µΩ
Explanation:
(a)the current in each strand is = the total current/ number of strand
0.876/ 200 = 4.38 × 10⁻³ A
(b) potential difference = IR
the total resistance = 2.26 µΩ × 0.876
= 0.395mΩ
c) resistance of the cable = 2.26 µΩ × 200
=452 µΩ
Answer:
The helicopter uses 35 gallons to fly for 5 hours.
Explanation:
The amount of gas that a helicopter uses for flying varies directly proportional to the number of hours spent flying.
g ∝ T
where g represents amount of gas and T time of flight.
Then,
The helicopter files 4 hours and uses 28 gallons of fuel.
Here, g₁= 28 gallons, T₁=4 hours
g₂=?, T₂=5 hours.
⇒28×5= g₂×4
⇒ g₂×4=28×5
gallons
The helicopter uses 35 gallons to fly for 5 hours.
Answer:
Ratio of wavelength will be 1.1982
Explanation:
We know that velocity in any medium is given by , here c is the velocity of light and n is the refractive index
We know that wavelength is given by , from the relation we can see that wavelength is inversely proportional to the refractive index
We have given refractive index of carbon disulfide = 1.632
And refractive index of ethyl alcohol = 1.362
So ratio of wavelength of ethyl alcohol and carbon disulfide =
