The string does not experience any force of tension, as it balances two forces acting in the same direction. Hence, the tension is zero.
Explanation:
If tension existed in the string, it would mean that two equal but opposite forces are exerting pull in contrary directions.
When a force of f newtons is applied from the right and another force of f newtons from the left, the resulting action occurs through one force. Because there is action on the same string in opposing directions, the tension in the string can only be equal to the magnitude of the string itself.
Therefore, the string indeed has no tension since it is dealing with two forces acting in the same direction. Thus, the tension is zero.
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.
Answer:
The answer I think fits this question is D.

I hope this is helpful and accurate.

To calculate the rate, first convert units properly. Since 1 kilogram equals 1,000,000 micrograms, 1.6 kilograms is 1,600,000 micrograms. One week has 604,800 seconds. Therefore, dividing 1,600,000 micrograms by 604,800 seconds gives the rate. Simplifying, this results in 2.65 µg/s. I hope this answers your question.
