Final answer:
Variable Cycles on a washer refer to different washing settings that cater to a variety of washing needs. The spin cycle uses centrifugal force to remove water from clothes by spinning the drum rapidly and draining the water.
Step-by-step explanation:
When referring to a washing machine, 'Variable Cycles' means that the machine offers different settings or programs designed for washing clothes under various conditions. These cycles adjust factors like the water temperature, spin speed, rinse times, and more. For instance, there might be cycles especially for delicates, heavy-duty washes, or quick washes.
During a spin cycle, a real force known as centrifugal force comes into play. This force effectively throws water from the clothes as the drum of the washer spins at high speed. The water is pushed out through the perforations in the drum and drained away, which results in the clothes becoming less saturated and therefore easier to dry.
