A light aircraft weighs 2,767 pounds empty weight and the center of gravity is 34 inches aft of the leading edge of the wing. The datum is the firewall which is 48 inches ahead of the leading edge. A new engine is installed that weighs 23 pounds less than the old engine. The engine weight is centered 22 inches ahead of the firewall. What is the new EWCG?

  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

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
