A pedestrian starts from A and goes 4 kilometre north to reach at. B He then walk 3 kilometre east to reach another place place what is the resultant displacement he made?

  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 components of a vector are the parts of the vectors that are to each other.
