1. A weight lifter lifts 100 kg of mass from the floor to a position above her head, 2.2 meters off the floor. a. How much work did she do on the mass?

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

  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
