B. Secondary-cell batteries can be recharged and used many times, whereas primary-cell batteries cannot be properly recharged
C. Primary-cell batteries use chemical cells, whereas secondary-cell batteries use an alternative energy source, such as thermal or magnetic energy, to supplement their outputs
D. Primary-cell batteries must be recharged at a much slower rate that secondary-cell batteries
E. None of the above

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.
