Using an Oscilloscope, it can be observed that the pitch of a sound is directly related to a sound waves frequency while the volume is directly related to a sound wave amplitude the change shown in the illustration suggest that the A) Pitch is Increasing
B) Pitch is Decreasing
C) Volume is Increasing
D) Volume is Decreasing

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
