Two small metal spheres with masses 2.0 {rm g} and 4.0 {rm g} are tied together by a 5.3-{rm cm}-long massless string and are at rest on a frictionless surface. Each is charged to +2.3 mu C. What is the energy.
You can ignore friction between the sled and surface of the pond. Use the work-energy theorem to find the speed of the sled at 3.00 m.
At a certain point, A, in its motion, its velocity angle is 19° above the horizontal. At another point, B, later in its motion, its velocity angle is 39° below the horizontal. Illustrate what is the horizontal distance from point A to point B?
Weak magnetic fields can be measured at the surface of the brain. Although the currents causing these fields are quite complicated, we can estimate their size by modeling them as a current loop around the equator of a 18--diameter (the width of a ..
