Is the field of the bar magnet uniform? is it axial (has components along the length of a bar magnet), radial (has components perpendicular to the length of the bar magnet) or both? when discussing flux of the magnetic field do you need to consider both components? explain.

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

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

Consider a system to be two train cars traveling toward each other. what is the total momentum of the system before the train cars collide?   kg • what must the total momentum of the system be after the train cars collide?   kg •
