The formula v = ir shows the relationship between voltage, current, and resistance. based from this formula, find the formula of r. a. r = vi b. r = v divided by i c. r = v + i d. r = v – i

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
