Answer:
D. 30 Ω
Explanation:
R₁ + R₂ = 33
-0.0005 R₁ + 0.005 R₂ = 0
Solve the system of equations for R₁.
-0.0005 R₁ + 0.005 R₂ = 0
0.005 R₂ = 0.0005 R₁
R₂ = 0.1 R₁
R₁ + R₂ = 33
R₁ + 0.1 R₁ = 33
1.1 R₁ = 33
R₁ = 30

Answer:
Its new current will be 240.0milliAmps
Explanation:
According to ohms law,
V = IR
V is the supply voltage in a circuit
I is the current
R is the resistance
If the current in the wires of a circuit is 120.0 milliAmps, the voltage will be:
V1 = 120R1
R1 = V1/120...(1)
If the voltage impressed across the ends of the circuit were doubled (with no change in its resistance),
V2 = 2V1
V2 = IR2
2V1 = IR2
R2 = 2V1/I ... (2)
Since there are no changes in resistance
R1 = R2
Equating 1 and 2, we have:
V1/120 = 2V1/I
1/120 = 2/I
Cross multiplying
I = 2×120
I = 240milliAmps
Answer:
The work done by you on the two cart system is 2 N-m
Explanation:
Work done is the product of force and displacement.
W = F * D
Substituting the given values we get -
W =
