The distance below the bridge that kate will eventually be hanging, once she stops oscillating and comes finally to rest is: d = mg/k + L.
<h3>Distance</h3>
LetForce exerted by a spring=F=kx
Let x = (d – L)
Let d= Total length of the bungee cord
Let set this equal to the gravitational force
F(spring) = k(d – L)
F(gravity) = mg
Hence:
k(d – L) = mg
(d – L) = mg/k
d = mg/k + L
Inconclusion the distance below the bridge that kate will eventually be hanging, once she stops oscillating and comes finally to rest is: d = mg/k + L.

The best way for andrea to build up a diversified portfolio of stocks is; by putting her money into dollar-cost averaging.
<h3>What is dollar-cost averaging?</h3>
Dollar-cost averaging is defined as an investment strategy in whereby the individual periodically purchases target assets or invests in a certain portion of funds in one security.
This therefore tells us that Dollar-cost averaging would reduce the risk tolerance associated with purchasing large stock securities.
Thus, we can recommend dollar cost averaging as the best way for andrea to build up a diversified portfolio of stocks.

Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio
