B) how many days of a diet of 2200 large calories are equivalent to the gravitational energy change from sea level to the top of mount everest, 8848 m above sea level? assume your mass is 72 kg. (the body is not anywhere near 100% efficient in converting chemical energy into change in altitude. also note that this is in addition to your basal metabolism.)

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
