Answer: The answer is B
Explanation: A correlation generally is a mutual relationship/connection or the process of establishing the relationship/connection between 2+ things
Answer: The drag force goes up by a factor of 4
Explanation:
The <u>Drag Force</u> equation is:
(1)
Where:
is the Drag Force
is the Drag coefficient, which depends on the material
is the density of the fluid where the bicycle is moving (<u>air in this case)
</u>
is the transversal area of the body or object
the bicycle's velocity
Now, if we assume
,
and
do not change, we can rewrite (1) as:
(2)
Where
groups all these coefficients.
So, if we have a new velocity
, which is the double of the former velocity:
(3)
Equation (2) is written as:
(4)
Comparing (2) and (4) we can conclude<u> the Drag force is four times greater when the speed is doubled.</u>
Answer:C..net work done on the object.

Answer: d. thunderstorms
The option <span>blizzards can be excluded as it is clearly not related to the evaporation. Floods can happen if the condensation rate high, not evaporation. Sometimes the cloud that carries water is just blown up by the wind so the evaporation does not happen in that place.
Thunderstorms happen more in summer because the rate of evaporation and condensation is increased.</span>
