Which statement does not explain the concept of the doppler effect? a) as an observer approaches a stationary sound, the sound waves are compressed, making the pitch higher. b) as an observer moves away from a stationary sound, the sound waves are stretched making the pitch lower. c) as a sound source approaches a stationary object, the sound waves are compressed, making the pitch higher. d) as a sound source moves away from a stationary object, the sound waves

What characteristics of hv2112 make it the best candidate to be classified as a thorne-zytkow object?

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
