Answer:
0.79
Explanation:
Using the formula it would be ----
A = πr^2
= π × 0.5^2 ≈ 0.7854
= π × 0.25 ≈ 0.7854
0.7854 rounded to the nearest hundredth would be 0.79

Explanation:
Your teacher created a 2 g/L salt-water solution (solution A) and a 2.5 g/L salt-water solution (solution B), both in 500 mL of water. Using the concentration equation, which solution is more concentrated? How do you know?
Answer:
Solution B,
A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute. However, these terms are relative, and we need to be able to express concentration in a more exact, quantitative manner.

Describe the oceanic crust NO LINKS
Answer:
oceanic crust is the relatively thin part of the earth's crust which underlies the ocean basins. It is geologically young compared with the continental crust and consists of basaltic rock overlain by sediments
Explanation:
I hope this helped ;)
Answer:
Oceanic crust, the outermost layer of Earth’s lithosphere that is found under the oceans. Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other.

Why does food need to be digested?
Answer:
Food needs to be digested so it can be broken down into sugar molecules and nutrients that can be used by the cell to stay alive.
Explanation:
I am a metalloid. I am in the nitrogen family and row 4. I have an atomic mass of 74.92. I can be used as a poison. Who am I?
Answer:
As – Arsenic
Explanation:
Let's break this down step by step. Make sure you have a periodic table to reference.
"I am a metalloid" – We will be looking towards the right side of the periodic table. The possible choices are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and astatine (At).
"I am in the nitrogen family" – Families are elements grouped by columns. The nitrogen family is group 15. The possible choices are now arsenic (As) and antimony (Sb).
"and row 4" – Counting from the very top (don't forget row 1 of hydrogen and helium), we can see that arsenic (As) is in the 4th row.
"I have an atomic mass of 74.92" – Arsenic (As) does have an atomic mass of 74.92, which confirms our answer.

Matter changes states during fusion and vaporization. How is this related to heat?
Answer:
When you heat up water, it starts to evaporate slowly into the air. When you fuse two things together, that takes a lot of heat to do. Both of these things are related to heat.
Explanation:
Answer:
At the point when you heat up water, it begins to vanish gradually into the air. At the point when you intertwine two things, that takes a great deal of warmth to do. Both of these things are identified with heat.

2. Make a 29 day timeline. Along the timeline draw and label the phases of the Moon starting with a full moon, crescent, first quarter, gibbous and full. Finish the second half showing the waning moons back to the new moon.
Dont know if this helps but here
Moon phases represent the names given to points in its orbit around Earth. Each phase lasts for only an instant as the moon constantly moves. To the naked eye, the full moon lasts about three days, but in reality, it is a full moon for just an instant before it begins to wane. The moon takes just under one month -- an average of 29 1/2 days -- to complete its phases.
TL;DR (Too Long; Didn't Read)
As the moon passes gradually and continually through its monthly cycle, each phase lasts only an instant. The Full Moon, for example, is simply a point halfway between waxing gibbous and waning gibbous.
Phases of the Moon
The moon has eight phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. But it is not as simple as dividing 29 1/2 by eight to find out how long each phase lasts. The fraction by which the moon is illuminated steadily increases or decreases at all times.
Primary and Intermediate Phases
The primary phases of the Moon cycle are the new moon, the first quarter, the full moon and the last quarter. The dates and times of these phrases -- which you can calculate or find on calendars -- change from month to month according to the positions of the Sun and the Moon. Astronomers refer to the crescent and gibbous phases as intermediate phases.
