A2.2 kg block rests on a frictionless wedge that has an inclination of 31◦ and an acceleration to the left such that the block remains stationary relative to the wedge; i. e., the block does not slide up or down the wedge. the acceleration of gravity is 9.81 m/s 2 .

Write down two additional questions about earth's magnetic field that will make your presentation more informative.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.

Ahorizontal force of 400.0 n is required to pull a 1760 n truck across the floor at a constant speed. find the coefficient of sliding friction.
