Lyon pulls on a 50. kg a wagon with a constant force of 340 N. Neglecting friction, the wagons acceleration will be (2 points) a 8.6 m/s2
b 7.4 m/s2
c 6.8 m/s2
d 6.6 m/s2
e 3.4 m/s2

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?

Which composition of water moves to begin a deepwater current?

Ahot-air balloon is 11.0 m above the ground and rising at a speed of 7.00 m/s. a ball is thrown horizontally from the balloon basket at a speed of 9.00 m/s. ignore friction and air resistance and find the speed of the ball when it strikes the ground.
