3 pts
when you stretch a rubber band, (mechanical energy) you are using your
own energy to give the rubber band potential energy. when you release
the band, its energy gets transformed into moving energy. (kinetic energy)
if i stretch a rubber band and fling it across the room. when does the
rubber band have energy?
o both when it is stretched tight and when it is flying across the room.
right before the teacher let the rubber band go.
o only when it is flying.
o only when it was stretched tight.

  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

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
