27. You are in a toob floating down the Guadalupe River. The river is flowing with 2 m/s. Your friend, who is 1 meter away, pushes the floating cooler in your direction with a velocity (horizontal to the river) of 0.5 m/s. See drawing below You Initial distance = Cooler = 0.5 m/s River = 2 m/s 1 meter Cooter How much time does it take for the cooler to reach you? b. What is the total velocity of the cooler during its journey between your friend and you? When catch the floating cooler, consider it an inelastic collision. If С. you your mass is 65 kg and the cooler is 10 kg, what is your final total velocity? a.
After sitting on a shelf for a while, a can of soda at a room temperature (73∘73∘F) is placed inside a refrigerator and slowly cools. The temperature of the refrigerator is 37∘37∘F. Newton's Law of Cooling explains that the temperature of the can of soda will decrease proportionally to the difference between the temperature of the can of soda and the temperature of the refrigerator, as given by the formula below: �=��+(�0−��)�−��T=Ta+(T0−Ta)e−kt ��=Ta= the temperature surrounding the object�0=T0= the initial temperature of the object�=t= the time in minutes�=T= the temperature of the object after �t minutes�=k= decay constant The can of soda reaches the temperature of 53∘53∘F after 30 minutes. Using this information, find the value of �k, to the nearest thousandth. Use the resulting equation to determine the Fahrenheit temperature of the can of soda, to the nearest degree, after 60 minutes. Enter only the final temperature into the input box.

The core of the Sun has a temperature of 1.5 × 107 K, while the surface of the Sun has a temperature of 4460 K (which varies over the surface, with the sunspots being cooler). Treat the core of the Sun and the surface of the Sun as two large reservoirs connected by the solar interior. Nuclear fusion processes in the core produce 3.8 × 1026 J every second. Assume that 100% of this energy is transferred from the core to the surface. Calculate the change in the entropy ΔS, in joules per kelvin, of the Sun every second. Rigel is a blue giant star with a core temperature of 5.0 x 107 K and a surface temperature of 12500 K. If the core of Rigel produces 60,000 times as much energy per second as the core of the Sun does, calculate the change in the entropy ΔSR, in joules per kelvin, of Rigel every second. Barnard’s Star is a red dwarf star with a core temperature of 7.0 x 106 K and a surface temperature of 3270 K. If the core of Barnard’s Star produces 5% as much energy per second as the…
