Acertain single ion channel is selectively permeable to k+ and has a resistance of 1.15 gω , therefore a current of potassium ions through the channel is possible. during an experiment, the channel is open for approximately 1.50 ms while the voltage across the channel is maintained at 81.5 mv . how many k+ ions travel through the channel during this time?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
