Jade has a refractive index of 1.61. If light approaches the gem at an angle of 80.0°, what is the angle of refraction? Calculate the index of refraction of a material if the angle of incidence is 60° and the angle of refraction is 50°

Gas will most likely  fill the container 

Multiply the 3 dimensions, assuming it is a rectangular cuboid, to get the volume in cm³ divide mass by volume to get density in g/cm³

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.

Because the sun is the biggest and if the sun orbits the earth we will be dead probably
