Answer:

<em>Dark matter and dark energy</em>

<em></em>

Explanation:

Dark matter is thought to make up about 85% of the mass-density make up the universe. Dark matters have not been observed by direct interaction, but indirectly by their interaction with the universe generally; producing some gravity effect that cannot be explained by the existing gravity laws except there is more matter in the universe than is accounted for. Dark energy is an unknown, and undetected energy that is thought to exist in the universe, and affects the universe on the largest scale. The existence of dark energy is the only explanation for why the universe is seen to be expanding at an accelerated rate, rather than at a constant rate. <em>These two element (dark matter and dark energy) make up a very large energy-mass portion of the observable universe.</em>

Ivahew [28]

Answer:

Her school classmates represent a <u>reference group</u>.

Explanation:

According to sociologists, a reference group refers to a group of people to which we compare ourselves regardless if we are close to them or not. We usually to this comparison by determining if we are accurately following certain social rules or norms. By being similar to them, we might feel comfort, feel like we are worth, or just feel like we are doing things "right."

In this case, this woman does not feel comfortable showing up at her meeting unless she got a promotion because she may feel like she is behind because she finished college later than them.

Luz, who is skydiving, is traveling at terminal velocity when she changes position by going headfirst toward the ground. What ha
Len [333]

Answer:

The velocity would increase as the surface area decreases

Explanation:

The force on a person falling is given by

F=\dfrac{1}{2}\rho CAv^2\\\Rightarrow v=\sqrt{\dfrac{2F}{\rho CA}}

where,

\rho = Density of air

A = Surface are

C = Drag coefficient

v = Terminal velocity

F = Drag force

It can be seen that the terminal velocity of a body is inversely proportional to the surface area.

Hence, the velocity would increase as the surface area decreases.
