What was the cart's instantaneous speed at 6 seconds?

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

think its the third option

neither accurate nor precise.

  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
