A. A spin stabilized satellite used solar cells mounted on a cylinder body that continuously rotates so that 40 a time and it also uses gyroscopic action of a spinning satellite to maintain its orientation towards the earth and the sun.
B. A spin stabilized satellite uses solar panels whose cells are continually oriented toward the sun
C. Satellite transponders use lower frequency reception of radiation from earth stations and higher frequency for transmission to earth stations.
D. satellite transponders use a single frequency for reception and transmission from one point on earth to another
Correct Answer: A spin stabilized satellite used solar cells mounted on a cylinder body that continuously rotates so that 40 a time and it also uses gyroscopic action of a spinning satellite to maintain its orientation towards the earth and the sun.
