Define Mach number
Mach number (E. Mach): It is the ratio of the speed of an object in a specified medium to the speed of sound in that medium.
What is the reason that heat causes matter to expand? Briefly explain it.
Define Hertz or SI unit of frequency: Hertz: Hz (after H. Hertz, 1857-1894): The derived SI unit of frequency, stated as a frequency of 1 cycle per s; it therefore has units of s-1.
Photoelectric effect: An effect described by A. Einstein that demonstrates that light seems to be made up of particles, or photons. The light can excite electrons (termed as photoelectrons in this context) to be ejected from the metal. Light with a fr
Obtain the “dot” equivalent for the circuit shown below and use it to find the equivalent inductive reactance. Q : Define Henry or SI unit of inductance Henry: H (after W. Henry, 1775-1836): The derived SI unit of inductance, stated as the inductance of a closed circuit in which the electromotive force of 1 V is generated whenever the electric current differs uniformly at a rate of 1
