Question

if a sattelite is moving in a km radius 4907 km calculate it's speed if it takes 22 hrs to revolve around the earth​

Answer 1

Answer:

Distance covered by the satellite in 24 hours

s=2πr

  =2×3.14×42250=265464.58 km

Therefore speed of satellite,

v=time takendistance travelled​=24×60×60265464.58​=3.07 km s−1

Answer 2

Answer:-

$\red{\bigstar}$ Speed of the Satellite $\large\leadsto\boxed{\tt\pink{1400.72 \: km/hr.}}$

• Given:-

• Satellite is moving in radius of 4907 km.

• It takes 22 hours to revolve around the sun.

• To Find:-

• Speed of the satellite.

• Solution:-

Given that, the satellite covers the distance of 4907 km in radius.

Hence,

Distance travelled by satellite in 1 revolution will be 2πr.

Also,

Speed = Distance/Time

Therefore, the final formula:-

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{Speed = \dfrac{2 \pi r}{Time}}}}$

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting in the values:-

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➠ $\sf Speed = \dfrac{2 \times \frac{22}{7} \times 4907}{22}$

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➠ $\sf Speed = \dfrac{2 \times 3.14 \times 4907}{22}$

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➠ $\sf Speed = \dfrac{6.28 \times 4907}{22}$

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➠ $\sf Speed = \dfrac{30815.96}{22}$

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➠ $\sf Speed = 1400.725455$

⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ $\large{\bf\red{1400.72 \: km/hr}}$

Therefore, the satellite is revolving with speed of 1400.72 km/hr.
