B. runs freely without any further power C is no longer affected by the Earths gravity D. does not meet with air resistance 5. Why is it not necessary to provide powered flight in space all the time? A. Few spacecraft complete their flight operations B. The spacecraft will be attracted by the moon C. No further power is needed after the escape speed is reached D.
