Answer:
Vc = 2.41 v
Explanation:
voltage (v) = 16 v
find the voltage between the ends of the copper rods .
applying the voltage divider theorem
Vc = V x (
)
where
- Rc = resistance of copper =
(l = length , a = area, ρ = resistivity of copper)
- Ri = resistance of iron =
(l = length , a = area, ρ₀ = resistivity of copper)
Vc = V x (
)
Vc = V x (
)
Vc = V x (
)
where
- ρ = resistivity of copper = 1.72 x 10^{-8} ohm.meter
- ρ₀ = resistivity of iron = 9.71 x 10^{-8} ohm.meter
Vc = 16 x (
)
Vc = 2.41 v
Answer:

Answer:
I would think it's A cat runs in a straight line.
Explanation:
The weight of an object is mass*acceleration. In this case mass*g.
1000*9.8=9800
So the car has a weight of 9800 N.
Answer:
See the explanation below.
Explanation:
Indeed this is a serial circuit, in order to calculate the different questions, we must calculate the current of the circuit. The total resistance of the circuit can be calculated by means of an algebraic summation.
Then using ohm's law,we can calculate the current.
Rt = 2 + 4 + 6 = 12 [ohm]
The current
I = V / Rt
I = 12 / 12
I = 1 [amp]
Therefore the voltage in each resistance will be:
V1 = 2 * 1 = 2 [V]
V2 = 4 * 1 = 4 [V]
V3 = 6 * 1 = 6 [V]
The total voltage will be:
V = V1 + V2 + V3 = 12 [V]
The power can be calculated by multiplying the voltage by the total current.
P = V * I
P = 12 * 1
P = 12 [W]
