Find the resultant force on an object if 100 N force acts at 45 degrees above the horizontal to the right and a second 100 N force acts 45 degrees below the horizontal to the right and a third force of 50 N acts to the left. (Give the magnitude and the direction). First draw the angied vectors and then "add" them correctly to get their resultant .

We found the centripetal acceleration of the earth as it revolves around the sun. compute the centripetal acceleration of a point on the surface of the earth at the equator caused by the rotation of the earth about its axis. (enter the magnitude. the radius of the earth is 6,371 km.)

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied
