A direct frequency modulated crystal oscillator has a frequency of 9.3 MHz. The varactor produces a maximum deviation of 250 Hz. The oscillator is followed by two triplers, a doubler, and a quadrupler. What are the final output frequency and the deviation

Select all the correct answers. which changes will increase the rate of reaction during combustion? decreasing the area of contact between the reactants adding more oxygen to the reaction removing heat from the reaction changing the reactants from solid form to powdered form lowering the exposure of the reactants to air
