Ray runs 30 feet north , 30 feet west , and then 30 feet south

Distance = 90ft. 30ft. 3oft. Displacement = 30ft west.

the higher the current the higher the mag field around it the higher the influence on the compass

  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
