hope this somewhat helps :)
Answer:
R = 6.3456 10⁴ mile
Explanation:
For this exercise we will use Newton's second law where force is gravitational force
F = m a
The satellite is in a circular orbit therefore the acceleration is centripetal
a = v² / r
Where the distance is taken from the center of the Earth
G m M / r² = m v² / r
G M / r = v²
The speed module is constant, let's use the uniform motion relationships, with the length of the circle is
d = 2π r
v = d / t
The time for a full turn is called period (T)
Let's replace
G M / r = (2π r / T)²
r³ = G M T²²2 / 4π²
r = ∛ (G M T² / 4π²)
We have the magnitudes in several types of units
T = 88.59 h (3600 s / 1h) = 3.189 10⁵ s
Re = 6.37 10⁶ m
Let's calculate
r = ∛ (6.67 10⁻¹¹ 5.98 10²⁴ (3,189 10⁵)²/4π²)
r = ∛ (1.027487 10²⁴)
r = 1.0847 10⁸ m
This is the distance from the center of the Earth, the distance you want the surface is
R = r - Re
R = 108.47 10⁶ - 6.37 10⁶
R = 102.1 10⁶ m
Let's reduce to miles
R = 102.1 10⁶ m (1 mile / 1609 m)
R = 6.3456 10⁴ mile
Answer:
This is the answer that I got.
Explanation:
Just check over it once.
Answer:
Due to the process of weathering and erosion.
Explanation:
- As the rocks are made of different forms of minerals they may have an igneous, metamorphic or sedimentary origin. Hence the natural stone surfaces can be made of granite, lime, or even shale.
- The process of physical weathering that is called as mechanical weathering of rocks tends to break them apart and leads to the development of crack and small openings.
- The diurnal exposure of bare rocks to extreme temperatures of day and night leads to onion peeling and slowly with water as an agent of erosion lead to cracks in joints of rocks.
