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 because it is the cheapest option
Explanation:
Fossils on continents that are now separated by <u>oceans</u> support the theory of continental drift.
<h3>What is the theory of
continental drift?</h3>
The theory of continental drift was proposed by Alfred Wegener in 1912 and it states that continental landmasses shift position over geologic time on Earth's surface, thereby, appearing to drift together across oceans and into each other.
Thus, the theory of continental drift is supported by Fossils on continents that are now separated by <u>oceans</u>.
Also, we know that continents that are closer to the equator have warmer climates but fossils of <u>tropic plants</u> have been found on islands near the North Pole, thereby, suggesting that islands drifted from the equator.
In conclusion, coal fields in <u>Europe</u> match those that are found in North America, and this supports the theory of continental drift.

The final rotational speed ω_final and the instantaneous power P delivered to the wheel are; ω_f = √((ω_i)² + 2(FL/(kmr²) and P = Frω_i
<h3>What is the Instantaneous Power?</h3>
A) From rotational kinematics, the formula for the final angular velocity is;
ω_f = √((ω_i)² + 2αθ)
where;
α is angular acceleration
θ = L/r. Thus;
ω_f = √((ω_i)² + 2α(L/r))
Now, α = T/I
Where;
I is moment of inertia = k*m*r²
T is t o r q u e = F * r
Thus;
α = (F * r)/(kmr²)
α = F/(kmr)
ω_f = √((ω_i)² + 2(F/(kmr))(L/r))
ω_f = √((ω_i)² + 2(FL/(kmr²)
B) Formula for instantaneous power is;
P = Fv
where at t = 0; v = rω_i
Thus;
P = Frω_i
