consider an electron between the plates of a charged capacitor. the figures below show situations where the potential across the capacitor and the separations between the capacitor plates vary specific values are given in each figure.

Tungsten-filament lightbulb emits light based on the temperature of the filament. which phenomenon does this demonstrate?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

A2000 kg car is rounding a curve of radius 200 m on a level road. the maximum frictional force the road can exert on the tires of the car is 4000 n. what is the highest speed at which the car can round the curve?
