Hola!!!
e#ball bearings are used to reduce friction and make it easier to move the object...
f#because their grooves and ridges becomes after many days of use if the tires becomes smooth then the friction would be reduced which could even slip the car or bus...
g#to reduce friction in order to reduce the heat produced....
h#to reduce air resistance (friction of air)...
i#to increase friction...because the icy roads already have very little friction or no friction at all....
j#rolling friction is very less and easy to move....
hope it helps ☺...
✌✌be brainly
