A50 kg satellite circles the earth in an orbit with a period of 100 min. what minimum energy e is required to change the orbit to one with a period of 310 min? assume both the initial and final orbits are circular. the earth’s radius is 6.37 × 106 m, its mass is 5.98 × 1024 kg, and the value of the universal gravitational constant is 6.672 × 10? 11 n · m2 /kg2 . answer in units of j.

7.4 x 10⁸ J

Explanation:

= mass of the satellite = 50 kg

= mass of the earth = 5.98 x 10²⁴ kg

= initial radius of the orbit

= initial time period of the orbit = 100 min = 100 (60) = 6000 s

Initial time period of the orbit is given as

= final radius of the orbit

= final time period of the orbit = 310 min = 310 (60) s = 18600 s

Final time period of the orbit is given as

Minimum energy required to change the orbit is given as

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
