where
T
is the orbital period,
R
is the distance between the center of the planet and the satellite,
G
is the gravitational constant, and
M
is the mass of the Earth.
The period of the orbit is approximately 8.86 hours.
The period of an orbit is the time it takes for a satellite to complete one full orbit around the Earth. The period is determined by the distance of the satellite from the Earth's center and the gravitational force acting on it.
We can find the period of the orbit using Kepler's third law of motion:
T² = (4π² × (R+h)³) / (G × M)
where T is the period of the orbit in seconds, h is the altitude of the satellite (500 miles), R is the radius of the Earth (4000 miles), G is the gravitational constant (6.67 × 10⁻¹¹ N(m/kg)²) and M is the mass of the Earth (5.97 × 10²⁴ kg).
First, we need to convert the radius of the Earth and the altitude of the satellite from miles to meters.
1 mile = 1609.34 meters
R = 4000 miles × 1609.34 meters/mile = 6,371,600 meters
h = 500 miles × 1609.34 meters/mile = 804,670 meters
T² = (4π² × (6371600 + 804670)³) / (6.67 × 10⁻¹¹ × 5.97 × 10²⁴)
T² = 1.087 × 10¹⁶
T = √(1.087 × 10¹⁶)
T = 3.296 × 10⁸ seconds
To get the period in hours, we divide by the number of seconds in an hour:
T = 3.296 × 10⁸ seconds / (60 × 60) = approximately 8.86 hours

the coriolis force is strongest when the wind speed is and the latitude is :
The coriolis force is strongest when the wind speed is high and the latitude is high
The magnitude of the Coriolis force is influenced by both wind speed and latitude variables. When the Earth rotates, the Coriolis force indicates that air and water appear to be deflected. In this instance, the wind generates the current, but Coriolis force determines its direction. When the wind speed is high and the latitude is high, the coriolis force is at its highest.
As wind speed is increased, the Coriolis force rises. The Coriolis force does not affect wind speed because it acts vertical to the direction of agitation (to the right of the wind in the Northern Hemisphere). And the opposite is also true: As coriolis force is increased, wind deviation increases.

One way increased coffee consumption can affect outside-area production is the way the land is now used. if the place is having increased coffee consumption then they'll most likely end up using more of their land and resources to grow this crop.
Farmers may choose to utilize their property differently as a consequence, concentrating more on growing coffee and less on other sorts of crops or activities.
This can lead to a decline in the diversity of crops cultivated in a region, increasing the need for pesticides and fertilizers as well as making the agricultural system more vulnerable to pests and diseases.

Lava, rocks, and steam are released to the surface of the earth through volcanoes. Magma is the term for the molten rock found deep within the Earth. Lava is what is left over from a volcanic eruption. Volcanoes typically originate along the boundary between two tectonic plates, which explains why the majority of the United States' volcanoes are found in the western part of the country, in Hawaii, and in Alaska.
It is estimated that 60% of all active volcanoes can be found near tectonic plate borders. The "Ring of Fire" refers to a belt where most volcanoes are concentrated.

Which interval contains the greatest amount of data?
50-100
Correct. This interval stretches from Q1 to well above the median, so we can be sure that it contains more than 25% of the data. No other interval has more than 25% of the data, so this is the best answer.
ABOUT BOXPLOTThe numerical summary function aside from showing data characteristics, can also be used to create box and point charts or better known as boxplots. The numerical summary needed to construct a boxplot is the Median, 1st Quartile, 3rd Quartile, Lowest data value, and Highest data value. For large numbers of observations or data sizes, the Median can be replaced with Trirata. This is because to calculate the Trirata value using three quantities, namely the Median, Quartile 1, and Quartile 3, so it is considered to be more representative of the data when compared to the Median.
The center line inside the box on the boxplot represents the Median value. The sides of the box flanking the Median show the 1st and 3rd Quartile values respectively. Meanwhile, the two ends of the boxplot represent the lowest data values and the highest data values.
Boxplot is very good to use for data with a large number of observations because it only takes 5 numbers to construct it. It's easy and fast to construct a boxplot because you don't need to draw all the observation points in the boxplot. Because only five important observation points are visible, the data picture can be seen more clearly.
In explorative data analysis, boxplot has several important functions. Boxplot is often used in detecting whether there are extreme/outlier data in a data set. In many statistical analyzes it is assumed that the data follows a normal distribution. Boxplot can also be used in testing these assumptions. In addition, a boxplot can also be used in comparisons of several populations.

According to plate tectonics, when a ridge forms with a rift valley, new crust is formed __________.
According to plate tectonics, when a ridge forms with a rift valley, new crust is formed on each side of the ridge equally.
When the Earth's tectonic plates separate, or rift, they leave behind a lowland area known as a rift valley. Rift valleys form both on land and underwater, as a result of seafloor spreading.The brittle surface layer of Earth (the lithosphere) usually breaks along parallel faults that angle slightly outward from each other when the lithosphere is torn apart.
The block between the faults breaks and sinks into the pliable interior when the plates separate along the boundary (the asthenosphere). A rift is created when the core valley of the block sinks. Liquid rock (magma) rises through the fissures. This process results in the formation of new crust along the margin. Volcanoes and earthquakes happen where magma rises to the surface along fault lines.
