- Saturn's moon Titan has a mass of 1.3452 x 1023 kg , a diameter of 5,150 km, and an atmosphere made mostly of N2 at a constant temperature of -179 degrees Celsius. Assume that the pressure at the surface is 50% more than on Earth. What is your best estimate of Titan's atmosphere's R constant?buckminsterfullerene, c60, is a large molecule consisting of 60 carbon atoms connected to form a hollow sphere. the diameter of a c60 molecule is about 7 x 10–10 m. it has been hypothesized that c60 molecules might be found in clouds of interstellar dust, which often contain interesting chemical compounds. the temperature of an interstellar dust cloud may be very low, around 3 k. suppose you are planning to try to detect the presence of c60 in such a cold dust cloud by detecting photons emitted when molecules undergo transitions from one rotational energy state to another. approximately, what is the highest-numbered rotational level from which you would expect to observe emissions? rotational levels are l= 0,1,2,3,..If a nonhuman civilization were to develop on Saturn's largest moon, Titan, its scientists might well devise a temperature scale based on the properties of methane, which is much more abundant on the surface than water is. Methane freezes at -182.6 °C on Titan, and boils at -155.2 °C. Taking the boiling point of methane as 100.0 °M (degrees Methane) and its freezing point as 0 °M, what temperature on the Methane scale corresponds to the boiling point of water on the Celsius scale, 100 °C? You must show all of the conversion steps.

- 153 kilojoules [kJ] of energy are expended lifting a pile of bricks 50 feet [ft] into the air. If each brick weighs 5 pounds-force [lbf] and has dimensions of 8 inches [in] x 2.25 inches [in] x 4 inches [in], calculate the number of bricks lifted. Round your answer to the nearest whole number of bricks.Heat is being transferred from the bottom of a saucepan of soup, to the top. Once convection begins, the temperature of the soup increases by 10 degrees Celsius. If it takes 3 minutes for the soup to increase temperature, and the mass of the soup is 2 kilograms, calculate the heat transferred per second in the process of increasing the soup's temperature. (The average specific heat capacity of the soup is 4000 J / kg C.) 44.4 Joules per second. 4444.4 Joules per second. 26667 Joules per second. 180 Joules per second. 444.4 Joules per second.What is the density of water vapor in the air on a hot, dry day in the desert when the temperature is 40.0 °C and the relative humidity is 5.00 %? The vapor pressure of water at 40.0 °C is Py = 7.34 x 10° Pa and the molecular mass of water is M = 18.0 g/mol. Enter your answer in units of grams per cubic meter. density: g/m3
- When working on a PHYS 1510 weekly assignment, a student decided to get a medium double double coffee from Tim Hortons (a coffee made with two creams and two sugars). After drinking it, the student looked up the nutritional value of the drink, and was shocked to find it was listed as 230.0 kcal (230.0 nutritional calories). After drinking the coffee, they weighed 87.88 kg. To work off all the calories, the student decides to climb the stairs in their building. How many floors do they need to climb to burn off the entire drink? (do not include units) Assume all floors are 3.00 m apart from each other. Assume all nutritional energy is fully converted to potential energy. 1 kcal = 4184 JThe goal in this problem is to find the growth of an ice layer as a function of time. Call the thickness of the ice layer L. (a) Derive an equation for dL/dt in terms of L , the temperature T above the ice, and the propertiesof ice (which you can leave in symbolic form instead of substituting the numbers). (b) Solve this differential equation assuming that at t = 0 , you have L = 0. If you have studied differential equations, you will know atechnique for solving equations of this type: manipulate the equation to get dL/dt multiplied by a (very simple) function of L on one side, and integrate both sides with respect to time. Alternatively, you may be able to use your knowledge of the derivatives of various functions to guess the solution, which has a simple dependence on t. (c) Will the water eventually freeze to the bottom of the flask?Instructions: Answer must be in standard form scientific notation with SI units that do not have prefixes except for kg. Provide the answer with the correct amount of significant figures. Thank you I greatly appreciate it
