produced? Have you ever noticed how your hair stands straight and stiff when you comb it vigorously on a dry‚ cold day? Or how difficult it is to remove dust particles from your comb? Your hair and the comb become charged by rubbing. This stationary electric charge is described as static electricity. Activity 1. Rub a plastic sheet with flannel and then hold the plastic sheet near Styrofoam bits. What do you observe? From the observations made‚ you can conclude that rubbing produces static electricity

Rousselle Molina date submitted: 5/29/13 ELECTRIC FIELD MAPPING I. ABSTRACT: In the Electric Field Mapping‚ we used charged electrodes to create an electric field on a glass tray with a piece of linear graph paper attached to the bottom. We tested several simple electrode positions by moving the probes and drew equipotential lines based on the voltage difference. We then confirmed that the equipotential lines run perpendicular to electric field lines by looking at the experimental data

What are electric cars and how do they help our environment? An electric car is an automobile that is propelled by one or more electric motors‚ using electrical energy stored in rechargeable batteries or another energy storage device. Electric motors give electric cars instant torque‚ creating strong and smooth acceleration. They are also around three times as efficient as cars with an internal combustion engine. The first practical electric cars were produced in the 1880s. Electric cars were popular

Everything has a trade-off and opportunity cost. Electric cars are no exception. The first thing that caught my attention was the mileage. In the article and video‚ Rick Peters’ electric car only goes 25 miles per hour. You cannot get very far with that‚ especially since the farthest you can go in it is 30 miles per charge. I drive a Toyota Camry‚ and I drive 9.2 miles every day to school. It takes me 12-15 minutes to drive to school. If you ignore the speed limit on the roads (it is 55 mph)‚ it
