What is the most likely evidence of an energy transformation taking place when a wire that is twisted and turned breaks? (5 points) Reddish glow is emitted as kinetic energy is transformed into thermal energy

Reddish glow is emitted as kinetic energy is transformed into electrical energy

Broken end of the wire turns hot as kinetic energy is transformed into thermal energy

Broken end of the wire turns hot as kinetic energy is transformed into electrical energy

Most energy in an ecosystem comes originally from_

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)

True or false graphs must include scales that increase by the same amount
