The first line caries 30 microCoulombs per meter, and the second line caries 435 microCoulombs per meter. What is the magnitude of force that one meter of the first line receives from the second line. The lines are 10m apart. I really don't know how to start. Can someone please explain this question. Thanks.

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

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
