A satellite orbits Pluto 1.20 x 105 m above its surface. Given that the mass of Pluto is 1.25 x 1022 kg and the radius of Pluto is 1.20 x 108 m, calculate the period of orbit of the satellite in seconds.
For #4 find r by adding the height of satellite to earth radius first, then solve for period using your formula for #2&3 ??
That looks OK.
For #8 - i have no clue .I find only 7 problems!
The Moon has an orbital period of 27.3 days around Earth and a mean distance of 3.84 ´ 105 km from Earth’s center. Use Kepler’s laws to find the orbital period of an artificial satellite orbiting Earth at a distance of 2.55 x104 km from the center of Earth
The distance between Pluto and the Sun is 57.2 times more than the distance between the Sun and Earth. Calculate the time taken by Pluto to orbit the Sun in Earth days.
For #5 [Ta/Tb]^2 = [ra/rb]^3 ??
For both 5 and 6
For 7 ; the electron problem, i have already posted.
