Answer:
Explanation:
The four wires are arranged in series: this setup indicates that the same current passes through them, while the total voltage from the battery, V0, equals the combined voltages across each resistor:
Additionally, the total resistance for this series configuration is
Using Ohm's law, we can determine the voltage V2 across wire 2:
(1)
Here, I represents the entire current flowing through the circuit, which is calculated as:
By substituting into equation (1), we derive V2:

Answer: Known facts are:
Sadie, the dam, is a black Labrador.
Sam, the potential sire, is a yellow Labrador.
Putting aside technical methods, the breeder can inspect the puppies for traits.
For instance, yellow coat color is recessive to black, so yellow pups would suggest Sam is likely the father; however black pups could also have Sam as sire if they inherited the mother's color alleles.
Examining coat color, conformation, and similar features is a reasonable starting point.
Ultimately these observations are probabilistic; the only definitive (scientific) method is a paternity (DNA) test.
C) B ⃗ = A ⃗ + C ⃗ Pay attention to the direction of the arrows (vectors).
