plz guys fast

Answer 1

Answer:

1.The lever is a movable bar that pivots on a fulcrum attached to a fixed point. ... It shows that if the distance a from the fulcrum to where the input force is applied (point A) is greater than the distance b from fulcrum to where the output force is applied (point B), then the lever amplifies the input force.

Components: fulcrum or pivot, load and effort

Examples: see-saw, bottle opener, etc

2. Blower is equipment or a device which increases the velocity of air or gas when it is passed through equipped impellers. They are mainly used for flow of air/gas required for exhausting, aspirating, cooling, ventilating, conveying etc. Blower is also commonly known as Centrifugal Fans in industry.

3.A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. ... During the time watermills operate channels tend to sedimentate, particularly backwater.
