 Grade 9 :: Simple Machines by jlovering
 When using a broom to sweep a floor, your mechanical advantage will be less than 1 and your fulcrum will be your hand at the top of the broom. This means the broom acts as a: Class 1 Lever Class 2 Lever Class 3 Lever Class 4 Lever
 Grade 9 :: Magnetism and Electricity by jlovering
 When you are at home, turning off a light usually does not turn off your T.V. This is because: Most electrical devices in a house are on parallel circuits Most electrical devices in a house are on series circuits They have different sources of voltage A T.V. does not require electricity.
