a battery contains two metals that have different tendencies to attract electrons if one is lithium with an electron affinity of -3.05 and the other is zinc with an electron affinity of -0.76 describe how the electrons will flow then describe how you could make this an even stronger battery

Which type of wave can travel without a medium

What is the measurement of how fast an object moves relative to a reference point?

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
