A cyclist and a motorcyclist ride on a straight road. The speed of a cyclist is 21.6 km/h , of a motorcyclist 68.4 km / h
After what time interval will the distance between them be 550 m , if at the beginning the distance between
them was 1375 m ?

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

answer and 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

it is a negative acceleration
