Which of the following statements is true about magnetic fields produced by current-carrying wires? a. the larger the current, the larger the magnetic field b. the smaller the current, the larger the magnetic field c. the longer the wire, the larger the magnetic field d. the longer the wire, the smaller the magnetic field

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

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
