Most weather occurs in which atmospheric layers?
Slav-nsk [51]

Answer:

Troposphere

Explanation:

The troposphere is the lowest layer of the Earth's atmosphere. The earth's atmosphere has the following layers:

- Troposphere - Stratosphere - Mesosphere -Thermosphere - Exosphere

The troposphere lies 10 km above the land surface and most weather phenomena and conditions (e. g. clouds, turbulence) occur there.

Most of the water vapor in the atmosphere is in the troposphere (about 99%) and most of the atmosphere's mass is contained in the troposphere (75%)

Maria is trying to meet her friends at the pool but construction is blocking her path from the parking lot directly to the pool.
pychu [463]

Answer:

Her displacement is 35 feet. Her distance is 75 feet.

If she walks 20 ft N, 35 ft E, and 20 ft S, it makes a rectangle with one missing side, which is 35. Her displacement is therefore 35, and 20 plus 35 plus 20 equals 75, which is the distance she walked.

Hope this helps!

What do scientist use the H-R Diagram for and how do they use it?
Vanyuwa [196]

Answer:

The H-R diagram can be used by scientists to roughly measure how far away a star cluster or galaxy is from Earth. This can be done by comparing the apparent magnitudes of the stars in the cluster to the absolute magnitudes of stars with known distances (or of model stars).

A satellite in a nearly circular orbit is 2000 km above earth's surface. the radius of earth is approximately 6400 km. if the sa
Ann [662]
Velocity is computed using the formula:

v= \frac{d}{t}
Where:
V = speed
d = distance traveled
t = time/period

First you need to consider that the orbit is circular. To get the measurement or the distance going around Earth, you will need to get the circumference of the path. 

C = 2 \pi r

Where:
C = circumference
π = 3.14
r = radius


The Earth has a radius of 6,400km, but you also need to consider that the satellite is orbiting above the surface of the Earth, so you add in the 2,000km to that radius. 

r = 6,400Km + 2,000Km = 8,400Km

Next step is to insert that into our circumference formula:

C = 2 \pi r
C = 2 \pi 8,400Km
C = 52,778.76 Km

The distance traveled would then be 52,778.76Km

Now that we have the distance, we can then get the velocity:

v= \frac{d}{t}
v= \frac{52,778.76Km}{12hrs}
v= 4,398.23km/hr

The speed of the satellite is 4,398.23km/hr.
