Kayakers wax their boats to a) reduce the work output b) reduce the weight of the kayak c) reduce their input force d) reduce the speed the boat traveles in water

Kayakers wax their boats to

c) reduce their input force

Wax is applied by the kayakers to reduce the force of friction between the water and surface of boat. reducing the force of friction between the water and surface of boat reduces the amount of force needed to gain a particular amount of acceleration. hence the input force is greatly reduced by waxing the surface of boat.

the answer is a. at the equator
