An astronaut, while on the Earth, gives a good kick to a soccer ball. The ball lands in tę seconds after the kick. The astronaut then takes the ball to the Moon where she gives it a somewhat weaker kick. As a result, the ball reaches exactly the same maximal height it reached previously on the Earth. What statement is true about the time tm that the ball spent aloft on the Moon? (The gravity on th Moon is 6 times weaker than on the Earth. You can rely either on a direct calculation, or on a dimensional analysis or both) A. tm=36 te
B. tm=12te
C. tm=te
D. tm=(6)^1/2 te
Е. tm=6te

Rohit is trying to tune an instrument

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.
