Answer:
The velocity from the personne flying over the island is
Explanation:
The island experiences a contraction of length, because the person who measures it, sees as if the island moves with a speed v. Relativistic Law, for an object with a velocity v and a length at rest Lo, and a length L at a velocity v :
Answer:
649kg/m^3
Explanation:
Let p be the density of this particular object.
Formula for density:
We can substitute the givenmass and volume to find density of the object.
Therefore the density of this object is 649kg/m^3.
111.0 because 111.009 rounds off to 111.01, thus rounding again off to 111.0
Answer:
a. Particles are in constant motion.
Answer:
Fossil fuels release carbon dioxide into the atmosphere. Natural gas is the best fossil fuel in terms of energy output per unit of carbon dioxide emitted. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass has the approximate chemical formula CHO.
