It is because you drink a lot of water. So the less water you drink the more yellow it is. It means you have healthy urine.
Answer:
0.037 N/m
Explanation:
The web acts as a spring, so it obeys Hook's law:
(1)
where
F is the force exerted on the web
k is the spring constant
x is the stretching/compression of the web
In this problem, we have:
- The mass of the fly is 
- The force exerted on the web is the weight of the fly, so:

- The stretching of the web is

So if we solve eq.(1) for k, we find the spring constant:

Answer: A) reactants
Explanation:
Reactants are the substances that have chemical reactions when they are combined, whereas the product is what comes from the reactants’ chemical reactions.
