A 10.0 ohm resistor, 20.0 ohm resistor, and a 25.0 ohm resistor are connected in series across a 110-V supply. Calculate the current in the circuit.
a 2.0 A
c.55 A
b. 4.5A
d. 11 A

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
