Which of the following is not true?(a) Battery is only used as a back

1.	Which of the following is not true?(a) Battery is only used as a back up(b) When in orbit, solar power is always available(c) Battery is used for initial satellite orientation and stabilization(d) The batteries are charged using solar power
Answer» Right option is (b) When in orbit, solar power is always available Best explanation: When a satellite goes into an eclipse or when the solar panels are not properly positioned, there is a temporary cut in solar power supply. In situations like this the batteries take over temporarily and keep the satellite operating. The batteries are not large enough to power the satellite for a long time; they are used as a backup system for eclipses, initial satellite orientation and stabilization, or emergency conditions.
