Question

The space shuttle orbits at 248 km per hour above the earth how often do the astronauts see the sunrise in minutes

Answer 1

Answer:

98.13 minutes

Explanation:

Given data:

Radius of the earth =  6800km.

Hence, Total radius of satellite orbit =  7048 km (6800+248) or 7048000m.

orbital period can be determine as

$T = 2\pi \sqrt{\frac{r^3}{Gme}}$

where,

r  = orbital radius,

m =  mass of earth

and Ge =  gravitational constant.

putting all value in above equation

$T = 2\pi \sqrt{\frac{(7.048\times 10^6)^3}{(6.67\times 10^{-11}\times 5.97\times 10^24)}}$

$= 6.28\times \frac{350.11}{39.82} \times 10^5$

  $= 58.88\times 10^2$

  = 5888 sec

  = 98.13 minutes
