Question
The height of a geo-stationary satellite from the
Earth's surface is approximately :Solution
A geostationary orbit is a circular orbit 35,786 kilometres above the Earth's equator and following the direction of the Earth's rotation. Communications satellites and weather satellites are often given geostationary orbits, so that the satellite antennas that communicate with them do not have to move to track them, but can be pointed permanently at the position in the sky where they stay.
- The product of two numbers is 4950 and their L.C.M is 225. What is the H.C.F of the two numbers?
What is the greatest number which divides 18, 29, and 40 and gives the remainder as 2, 3, and 4 respectively?
Determine the highest common factor (HCF) of the numbers 75, 125, and 300.
Two numbers are in the ratio 3:7. The product of their H.C.F. and L.C.M. is 2541. The sum of the numbers is:
