Answer:
The solution is given in the attachments.
(a) In a 3-phase, 4-wire system, the currents are in the A, B, and C lines under abnormal conditions of loading were as follows:
IA = 100/30° A, 1b = 50/300° A, and Ic = 30/180° A
(i) Calculate the positive, negative, and zero-phase sequence currents in the A-line.
(ii) Calculate the return current in the neutral conductor.
(b) Check by sketching IA, IB, and Ic as the sum of the appropriate symmetrical components.

Answer:
eccentrcity of orbit is 0.22
Explanation:
GIVEN DATA:
Initial velocity of satellite = 8333.3 m/s
distance from the sun is 600 km
radius of earth is 6378 km
as satellite is acting parallel to the earth therefore
and radial component of given velocity is zero
we have
h = 6.97*10^6 *8333.3 = 58.08*10^9 m^2/s
we know that
so
solvingt for
therefore eccentrcity of orbit is 0.22
