Question

an artificial satellite is moving in a circular orbit of radius 42250 km. Calculate the speed if it takes it 24 hrs to revolve around earth

Answer 1

Answer:

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

Answer 2

3.07 kms −1

Distance covered by the satellite in 24 hours

s=2πr

=2×3.14×42250=265464.58 km

Therefore speed of satellite,

v=time taken

distance travelled

= 24×60×60

265464.58

=3.07 km s −1
