Answer:
Electromotive force or e.m.f is defined as the battery's energy per Coulomb of charge passing through it. like other measures of energy per charge emf has SI unit of volts , equivalent to joules per coulomb.
1 meter = 100 centimeters, so 2.8 meters is 280 centimeters.
Answer:
Because frequency and wavelength are related by a constant (c) the energy can also be written in terms of wavelength: E = h · c / λ.
Answer:
the Answer is B because that what I know
