. In principle, one could think about triggering the photogate on the glider itself, instead of using a flag, i. e. record the time it takes the entire glider to pass the photogate. Would this make the measurement of the speed more or less accurate

What is special about a dc circuit ?

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?

What are the necessary conditions for fusion?
