Increasing particle vibration would have this effect

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

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
