Question

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

Answer 1

Answer:

में उपग्रह द्वारा तय की गई दूरी २ ४ घंटे

रों=2 π आर

=2×३ । 1 4×४ २ २ ५ ०=२ ६ ५ ४ ६ ४ । ५ 8 के एम

इसलिए उपग्रह की गति,

v=

समय लगेगा

यात्रा की दूरी

=

२ ४×६ ०×६ ०

२ ६ ५ ४ ६ ४ । ५ 8

=३ । 0 7 के एम रों

- 1

Answer 2

Explanation:

• To find:-

Speed of satellite.

• Equations given:-

Distance - 42250 km.

Time - 24 hours.

• Formula of speed:-

Distance / Time (km/hr)

• Circumference of orbit:- 2πr

= 2×22/7×42250

= 265571.43 km.

• Solution:-

As speed formula is given we only have to put the equations in the formula i.e. ,

=265571.43 /24 (km/hr)

= 11065.47 km/hr

So the speed of satellite is 11065.47 km/hr
