- The number density of air in a child's balloon is roughly the same as sea level air, 1019 particles/cm3. If the balloon is now 16 cm in diameter, to what diameter (in km) would it need to expand to make the gas inside have the same number density as the ISM, about 1 particle/cm3?arrow_forwardHow do we solve for it ?arrow_forwardSuppose you gathered a ball of interstellar gas that wasequal to the size of the Earth (a radius of about 6400 km). Ifthis gas has a density of 2.8 hydrogen atoms per cm3, typicalof the interstellar medium, what would its total mass be?

Roughly how many dust particles are in a cloud containing 1000 Msun of dusty gas if 1% of the cloud's mass is in the form of dust grains? B) What surface area would be covered by these grains if you put them side by side? Assume these grains are spherical. Answer in square light-years. C) Estimate the total surface area covered by the cloud assuming it's matter density is like that of a typical molecular cloud, about 10-21 g/cm3 (Hint: first calculate the clouds volume from it's mass and density, then determine its radius using the formula for volume of a sphere) Answer in square light-years.

- You decide to go on an interstellar mission to explore some of the newly discovered extrasolar planets orbiting the star ROTOR. Your spacecraft arrives in the new system, in which there are five planets. ROTOR is identical to the Sun (in terms of its size, mass, age and composition). From your observations of these planets, you collect the following data: Density Average Distance from star (AU] Planet Mass Radius Albedo Temp. [C] Surf. Press.
