Asap! fill in the blanks. a swinging pendulum is a good example of an exchange between energy (greatest at the bottom) at the bottom of its swing energy (greatest at the top) as it swings back up to the top of its swing.

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)

What causes the formation of ocean currents?

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
