Satellite a revolves around earth 5 times a day. what is the radius of its orbit, measured from earth's center? assume that earth generates the only significant gravitation attraction on the satellite. note: the mass of earth is 5.98 × 1024 kg, and the constant of universal gravity (g) equals 6.674 × 10-11 n · m2/kg2.

0.69 × 107 m

7.22 × 107 m

2.11 × 107 m

1.44 × 107 m

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
