The meaning of stating that a quantity such as linear momentum is conserved.

Answer to Problem 1ASA
When a quantity is said to be conserved in a process, it means that the quantity has the same (magnitude and direction) both before and after the process. If a collision process is considered, the linear momentum of the total system before collision will be equal to that after collision, and hence linear momentum is conserved in the collision process.
Explanation of Solution
Conservation of physical quantities are very important in physics. There are many conservation laws such as conservation of linear momentum, conservation of
The linear momentum conservation is one of the major conservation laws in physics. If collision process is considered, the linear momentum of the system before collision will be equal to that after collision.

- A spectra is a graph that has amplitude on the Y-axis and frequency on the X-axis. A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced. If the Fo of a sound is 125 Hz, please sketch a spectra (amplitude on the Y axis, frequency on the X axis) of the harmonic series up to the 4th harmonic. Include actual values on Y and X axis.arrow_forwardSketch a sign wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forwardSketch a sine wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forward
