The period is 1.5 , so it takes [1.5 hours for the satilete to make 1 full orbit around the earth]. The frequency is [1/5], so in 1 h the satellite [ orbits the earth ]. In 1 day, the satellite goes around Earth [5 ] times.
The amplitude is about , so the satellite is [ at a distance of 7000 from the earth ]. Earth’s radius is [25,484], so the satellite is [ 18,484 kilometers away from earth].
The period = 1.5 hrs
The frequency = 1 / period = 1 / 1.5 = 2 / 3
So...in one hour....the satellite makes 2/3 of an orbit [revolution ]
In one day.....the satellite makes 24 / 1.5 = 16 revolutions
The amplitude of the graph is 7000 km......[ 7000 km above the Earth's center ]
I don't understand this sentence ..." Earth’s radius is [25,484], so the satellite is [ 18,484 kilometers away from earth]."
The Earth's radius in km = 6371 km.....so.....the max distance that the satellite is above the Earth's surface is 7000 - 6371 = 629 km
For the last one you were confused on the question told me to take note that the diamter of the earth is 12,742 km .
So i would change it to , Earth’s radius is [6,371], so the satellite is [ 629 km above the Earths surface ]. ? is that better?
I was way off calcualtions it would 6,371 since the diameter is 12,742.
I think that is what you need, Jenny
This is a poorly worded question....unless the orbit varies from a circular path....the satellite is ALWAYS 7000km from the Earth's center!!!
