How will you describe the magnetic field around a current-carrying coil?
a. the magnetic field is weakest near and around the coilb)the magnetic field vary directly with the distance from the coilc)the magnetic field is strongest inside the current-carrying coild)the magnetic field lines are closed loops along the loops in the coil

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
