Seismic Waves. When you toss a pebble into a pond, it creates radiating waves in the water. An earthquake does the same thing with energy. When the plates fracture or slip, energy is released as seismic waves [source: USGS ]. There are several types of seismic waves. Body waves move through the inside of the Earth. There are two types of body waves: Primary waves (or P waves) are the fastest moving waves, traveling at 1 to 5 miles per second (1.6 to 8 kilometers per second). They can pass through solids, liquids and gases easily.
A #10 screw is bigger than a #8 screw and both of them are smaller than a quarter inch.0 is bigger.... the second number is threads per inch... so 10/32 or 10/24, 24 is a coarse thread and the 32 is a fine thread.... the last number is the length of the screw... 10/32 - 1 1/2 is a #10 screw with 32 threads per inch and is an inch and a half long.

Report Abuse. these come in various lengths as m3 or m4 just refers to the size of the threads on the screw and if you need longer ones..all you have to do is ask for m3 by 1/2 or m3 by 3/4 or m3 by 1 inch or longer.est Answer: Just refers to thread size of the screw/bolt, M3 is 3mm, M4 is 4mm etc. The numbers cast on the top refer to tensile strength for future reference.
