The chart below lists six stars. Research the visual luminosity, distance from Earth, and surface temperature of each star. Make sure to research credible sites, such as nasa. gov, to complete your chart. Distances should be given in light years and temperatures given in Kelvin. Visual luminosity (L) is how bright something is in human eyesight. As you conduct your research, look for the visual luminosity of each star relative to the Sun. (Therefore, the visual luminosity of the Sun is 1). If your sources give a fraction for visual luminosity, convert the fraction into a decimal number. Use your research to complete the chart.

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?
