Asinusoidal wave traveling in the negative x direction (to the left) has an amplitude of 20.5 cm, a wavelength of 28.5 cm, and a frequency of 15.0 hz. the transverse position of an element of the medium at t = 0, x = 0 is y = −3.00 cm, and the element has a positive velocity here. we wish to find an expression for the wave function describing this wave.

Which simple machine is not part of this compound machine? a. lever b. pulley c. inclined plane d. wheel and axle

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
