(Figure 1) In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. Part A What is the minimum rotational frequency, in rpm, for which the ride is safe? Express your answer in revolutions per minute. Figure 1 of 1 • View Available Hint(s) 1ν ΑΣφ ? f = rpm Submit

A 0.20-kg billiard ball bounces back and forth without losing its energy between the cushions of a 1.5 m long table. (a) If the ball is in its ground state, how many years does it need to get from one cushion to the other? You may compare this time interval to the age of the universe. (b) How much energy is required to make the ball go from its ground state to its first excited state? Compare it with the kinetic energy of the ball moving at 2.0 m/s.

Astronomers have recently discovered a new planet in a faraway solar system with a radius of roughly 395 km.395 km. Spectroscopic results indicate that the atmosphere, whose height is much smaller than the planet's radius, is largely argon, making the discovery truly controversial. Experts have deduced that argon is unlikely to be generated from the planet itself, therefore it is assumed that the argon in the atmosphere was created at the inception of the planet and is completely contained by its gravitational attraction. However, wide disagreement abounds about the composition of the planet. The surface of the planet is clearly composed of aluminum oxide, but some astronomers claim that this aluminum oxide is only a thin crust and that the planet is mostly iron. Given that the atmospheric temperature is 512 ∘C,512 ∘C, calculate the minimum density ?ρ of the planet so that its atmosphere could contain argon atoms. The molar mass of argon is 39.948 g/mol39.948 g/mol and the…

(Example: "The train radio vomited upon Montag, in retaliation, a great ton-load of music made of tin, copper, silver, chromium, and brass." p 75) What literary element is being employed here? Select 2 correct answers) A. The simile of metals helps the reader to picture the modern style of the transportation and furniture. B. The imagery of metals and shiny, hard substances symbolizes the artificial world that has been created to make people think they are living well. C.

My physics class has turned to online due to the COVID-19 and I am having trouble with some of the word problems my teacher gave me to work on. She presented me with: I am contemplating a career change. If I had 500g of stolen gold jewelry, how much energy would I have to add to it to melt it (so that it was not longer recognizable)? Pretend that it is pure gold. Would you be able to show me how to accomplish this problem so I can see the steps? Thank you for your time. John Payton
