Harley Quinn is riding her motorbike south along a flat , horizontal road . The total weight of Harley and her hog is 1800 N. The engine exerts a 600 N force forward . The air resistance acting on Harley and the bike is 200 N. The total friction between the tires and the road is 100 N. a ) Draw a f. b. diagram for the system that includes Hayley and her motorbike.
b ) Calculate the net force on the system.
c ) Determine the mass of Hayley & her motorbike.​

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
