A satellite orbiting earth has a tangential velocity of 5000 m/s. earth’s mass is kg and its radius is m. which is the distance of the satellite from earth? 1,500,000 m 2,240,000 m 9,608,000 m 16,008,000 m
The distance of the satellite form the earth is:
9,608,000 m (Option C) in Standard form, this is written as 9.6 x 10[tex]^{6}[/tex].
An Orbiting Satellite is a satellite that goes around the earth in an elliptical path known as an orbit.
To calculate the distance of the satellite from the earth we must equalize the force of Gravity to Centripetal Force given that these are the two forces that are at play here.
Step 1:
Equation that equalizes Gravity to Centripetality is:
G = mM/r² = m(v²/r)
Note that G = 6.67 x 10[tex]^{-11}[/tex] (This is a gravitational constant.)
m is the Mass of the Satellite
M is Mass of the Earth
r is the distance of the satellite from the center of the earth
v is the satellites tangential velocity
Step 2 - Rearrange the formula and substitute the numbers above to get r
r = G (m/v²) = (6.67 x 10[tex]^{-11}[/tex]) (6 x10[tex]^{24}[/tex]/5000²) =
= 1.6 x 10[tex]^{7}[/tex]m
Recall that form our postulation above, this is the satellites distance form the center of the earth.
To get it's distance form the earth's surface, we must know remove the value of the radius of the earth from the calculation. Where radius of the earth is given a r'
Hence,
r' = r - R = 1.6 x 10[tex]^{7}[/tex]m - 6.4 x 10[tex]^{6}[/tex]m
= 9.6 x [tex]10^{6}[/tex]m or 9,608,000 m

Which country has a coastline on the pacific ocean?.
Answer:
Honduras is considered to have a coastline on the Pacific Ocean since it borders the Gulf of Fonseca on the southern side.
Due to its southern boundary with the Gulf of Fonseca, Honduras is regarded as having a coastline on the Pacific Ocean.
The area where land meets the ocean, or as a line defining the border between the land and the shoreline, is known as the coast, sometimes known as the coastline or seashore.
The terrain of the area's surroundings has an impact on shorelines, as do water-induced erosion processes like wave action. The sort of beach that is produced depends on the rock and soil's geological makeup. The length of the coastline on Earth is around 620,000 km (390,000 mi). Natural ecosystems' coasts are significant zones and frequently the site of a diverse spectrum of biodiversity.

In a region of a continent that has not experienced significant uplift in 200 million years, a geologist would expect rivers to be characterized by
In a location of a continent that has not undergone important upthrust in 200 million years, a geologist would anticipate rivers to be characterised by Broad floodplains and travelling consecutive course.
Who is geologist?Geologist is a person that study the solid, liquid, and gaseous stuff that makes up Earth and other terrestrial planets, as well as the processes that shape them.
When there is upliftment, the stream or river has a steep gradient and forms a V-shaped valley, which is impossible to do in level ground.
Because it's a flat location, there's less weathering, so the chances of a natural leve forming are slim, and the third possibility, a rapid, which is a minor waterfall that originates in a highland area, is also out.
Therefore, there is no impediment to vary its path and constantly follow a straight path, a vast flood plain with a straight course is achievable in a flat location.
