A 50 kg person is standing at the back of a 2.5 meter long rowboat. If the person walks to the opposite end of the rowboat , by how many meters will the center of mass of the boat change?

i would think it's food chain

  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 ima (higher than 1m) will be greater than the ima with the height of 1m.
