An alpha particle (helium nucleus) has velocity vvl+vyj + 2k km/sec in a region with magnetic field b = 101-20) + 30k mt·the x-component of the force is 4x1017 n and the y-component is 2x101 n. what are v, vy, and f?

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
