a space walker conducts a sound experiment on a space walk by striking a tuning fork with a mallet. instrumentation is used to detect sound waves. which explains the results of this experiment?
a.
sound waves are mechanical waves and don't require a medium. sound does travel in the vacuum of space, so a sound would be produced and detected.
b.
sound waves are electromagnetic waves and don't require a medium. sound does travel in the vacuum of space, so a sound would be produced and detected.
c.
sound waves are mechanical waves and must travel through a medium. sound does not travel in the vacuum of space, so no sound would be produced or detected.
d.
sound waves are electromagnetic waves and must travel through a medium. sound does not travel in the vacuum of space, so no sound would be produced or detected.

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
