Two pedestrians A and B starts from the same point in the middle of the top side, only B starts 3 sec early. The speed A is 5 metres per sec, the speed B 4 metres per sec.

we need some answer choices, or something like that

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
