Work force × distance moved Assuming you are lifting at a constant speed, the upward force you exert is equal to the object's weight, so: Work weight × distance The distance is just how far you lift itSo: Work weight × height In the first problem: Work (600N)×(3m) 1800 Newton-meters (also called 1800 Joules) In the 2nd problem: Work (4000N)×(10m) 40,000 Newton-meters (40,000 Joules).
Well If An Earthquake were to occur in Chicago, I would go to the Basement and Hide underneath a HARD and STRONG table
Under a table or a void in the house if you are caught insideAlways have a battery operated radio, and a flash lightIf you are caught outside you are best to find wide open space where nothing can tip over onto youStay away from the balcony.
