Suppose an electrically charged ruler transfers some of its charge by contact to a tiny plastic sphere. will the ruler and the sphere attract or repel afterward? explain.

the correct choice is a .

do not post any more test or exam questions on

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
