An 18 Ω resistor and 30 Ω resistor are connected in series to an unknown voltage source. A very special tool measures the electron flow to be 8.2(10)18 e- to flow through the circuit per second in a clockwise direction.

a. What is the current in the circuit?
b. What is the voltage of the source?
c. What is the total power generated by the components?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

Frank just graduated from eighth grade. assuming exactly four years from now he will graduate from high school how many seconds does he have until his high school graduation

With physics question #5? for any !
