The text says that the local fluff, which surrounds the sun, has a temperature of 7500 k and a density 0.1 atom per cm3. the local fluff is embedded in hot gas with a temperature of 106 k and a density of about 0.01 atom per cm3. are they in equilibrium? (hint: in pressure equilibrium, the two regions must have nt equal, where n is the number of particles per unit volume and t is the temperature.) what is likely to happen to the local fluff?

If vx = 7.00 units and vy = -7.60 units, determine the magnitude of v⃗ . determine the direction of v⃗ .

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
