a concrete block of mass 35kg is pulled along a horizontal floor with the aid of a rope inclined at an angle of 30 degrees to the horizontal if the coefficient friction is o.75 calculate the force requiredto move the block over the floor

How is zig zagging a form of acceleration?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

In a series circuit the __ is the same at every point
