Q. What is the highest speed with which a 1550 car can round a turn of radius 76 on a flat road if the coefficient of static friction between tires and road is 0.50?

Q. The membrane surrounding the living cell consists of an inner and an outer wall that are separated by a small space. suppose that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 6.90 10-6 C/m2. What is the magnitude of the electric field within cell membrane? Find out the magnitude of the electric force that would be exerted on the potassium ion (K+; charge = +e) placed inside the membrane.
