calculate the magnetic flux density of a charge at a distance of 10cm in air from north pole with a magnetic strength of 10000 A. M​

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

What is the final velocity of the initial velocity of 25 and -50?

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
