Two coils of inductance 20 H and 12 H, respectively are connected in parallel. A third coil of inductance 3 H is connected in series with the parallel combination. Find the total inductance of the arrangement.

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

The energy produced as a result of this flow of electrons from atom to atom is called
