Under certain circumstances, potassium ions (K ) move across the 8.0nm thick cell membrane from the inside to the outside. The potential inside the cell is -70mV and the potential outside is zero. A) What is the change in electrical potential energy of the potassium ions as they move across the membrane

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

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
