Models of the first star-forming clouds indicate that they had a temperature of roughly 200 k and a particle density of roughly 300,000 particles per cubic centimeter at the time they started trapping their internal thermal energy. estimate the mass at which thermal pressure balances gravity for these values of pressure and temperature. how does that mass compare with the sun's mass? what is the estimated lifetime of a star with that mass?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
