Which statement best explains how the rock shown in this photo was deformed

Explain vector addition, triangle method and parallelogram method

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
