what if i don't get it at all :(

A standing wave pattern on a string is described by y(x, t) = 0.086 sin (8πx)(cos 64πt), where x and y are in meters and t is in seconds. For x ≥ 0, what is the location of the node with the (a) smallest, (b) second smallest, and (c) third smallest value of x? (d) What is the period of the...

A stationary motion detector sends sound waves of frequency 0.0620 MHz toward a truck approaching at a speed of 40.5 m/s. What is the frequency of the waves reflected back to the detector? (Take the speed of sound to be 343 m/s.) Please provide a solution rather than just an answer :) I...

Pressure p, volume V, and temperature T for a certain material are related by p= A T/V - B T^2/V where A and B are constants with values 358 N·m/K and 0.217 N·m/K2. Find the work done by the material if the temperature changes from 264 K to 310 K while the pressure remains constant...

The 3.00 kg cube has edge lengths d = 6.30 cm and is mounted on an axle through its center. A spring (k = 950 N/m) connects the cube's upper corner to a rigid wall. Initially the spring is at its rest length. If the cube is rotated 3.00° and released, what is the period of the resulting SHM...
