<h2>Weight of astronaut 2450 miles above the Earth is 80.38 pounds</h2>
Explanation:
Given that gravitational force, F, between an object and the Earth is inversely proportional to the square of the distance from the object and the center of the Earth.
Where F is gravitational force between an object and the Earth, r is the distance from the object and the center of the Earth and k is a constant.
Radius of Earth = 4000 miles
In case 1 an astronaut weighs 209 pounds on the surface of the Earth,
Now we need to find weight of astronaut 2450 miles above the Earth
r = 4000 + 2450 = 6450 miles
Weight of astronaut 2450 miles above the Earth is 80.38 pounds
Answer:
Explanation:
Given:
- file size to be transmitted,
- transmission rate of data,
- propagation speed,
- distance of data transfer,
<u>Now the delay in data transfer from source to destination for each 10 Mb:</u>
<u>Now this time is taken for each 10 Mb of data transfer and we have 30 Mb to transfer:</u>
So,
