Aforce does +190 j of work when it acts on a moving object and its direction is in the same direction as the object's displacement. how much work does this force do when the angle between it and the object's displacement is 56°? (assume the displacement is the same.)

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?
