Aparticular hot air balloon can be considered a sphere with diameter of 21m. the air inside the balloon is 60 celcius while the outside is 15 celcius. in reno, the balloon launches (just barely) with 4 people on board. the next day , the balloon goes to sacramento to launch with the same load and same temperatures (inside and outside the balloon). will the balloon launch(will it rise up? ) if yes, then how much extra load can they carry and still launch? if no, then how much load do they need to throw over board to launch? in both cases give answer in kg. note that the ambient pressure is different in the two cities, due to the substantial difference in elevation.

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
