Sean, an astronaut stands on the edge of a lunar crater and throws a Frisbee™ horizontally with a velocity of 5.00 m/s. With no atmosphere on the moon, the Frisbee ™ will not have any force of lift so it will “fly” like a stone. The floor of the crater is 77.0 m below the astronaut. What horizontal distance will the Frisbee™ travel before hitting the floor of the crater? (The acceleration of gravity on the moon is 1/6th that of the Earth).​

The specific heat of silver is 0.057 calories/gram°c. if 10.0 grams of silver were heated and the temperature of the sample changed by 20.0°c, how many calories of heat energy were absorbed by the sample?

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.
