Jupiter's satellite europa orbits jupiter with a period of 3.55 d at an orbital radius of 6.71 108 m (assume the orbit to be circular). g = 6.67 x 10-11 nm2 /kg2 (a) determine the mass of jupiter from the data given. (b) what is the orbital velocity of europa? (c) what is the gravitational field’s magnitude at europa?

(a)

M = 1.898 x 10^27 kg

(b)

v = 13.74 km/s

(c) E = 0.28 N/kg

Explanation:

Time period, T = 3.55 days = 3.55 x 24 x 3600 second = 306720 s

Radius, r = 6.71 x 10^8 m

G = 6.67 x 10^-11 Nm^2/kg^2

(a)

M = 1.898 x 10^27 kg

(b) Let v be the orbital velocity

v = 13739.5 m/s

v = 13.74 km/s

(b) The gravitational field E is given by

E = 0.28 N/kg

which three statements are true about all alloys?

i think the answer is a, hope this : )
