What is Conductors and insulators
Conductors - one or more electrons from each atom in solid can move freely by body conducting electric charge (metals)
Insulators - electrons are strongly bound to nuclei inhibiting electric charge (plastics, rubber, and glass)
Davisson and Germer scattered electrons from a crystal of nickel. The scattered electrons formed a strong diffraction pattern. What important conclusion was drawn from this experi

Mach number (E. Mach): The ratio of the speed of an object in a provided medium to the speed of sound within that medium. Mach's principle (E. Mach; c. 1870) The inert
Compare and contrast the pattern which is seen with two coherently illuminated narrow slits in Young's experiment with that seen for a coherently illuminated one slit producing dif
Hubble's law (E.P. Hubble; 1925): A relationship discovered among distance & radial velocity. Further away a galaxy is away from is, the quicker it is receding away from us. T

How are amps and watts related? In a nutshell, the power (measured in watts) dissipated by a resistance is directly proportional to the square of the current (measured in amper
Determine the real position of an air bubble in a glass cube of side 0.3m if the bubble seems to be at a distance of 0.05 m from one face and at 0.15m from the opposite face.
