Lots of points how much time would it take a crane to unload a railroad car of scrap metal if: 1. the total load of scrap metal weighs 50,000 n 2. the crane must carry the load a distance of 20 meters. 3. the power of the crane is 2,000 watts. 4. the crane can carry 3,000 n of metal at a time. 5. it takes 30 seconds for the crane to pick up the load, carry it 20 meters, drop it and return to the railroad car. solve and give an explanation.

Adisk with a radius of r is oriented with its normal unit vector at an angle q with respect to a uniform electric field. which of the following would result in an increase in the electric flux through the disk? check all that apply? a. increasing the area of the disk b. decreasing the given orientation angle of the disk c. decreasing the strength of the electric field d. increasing the given orientation angle of the disk, but not exceeding an angle of 90
