Step by step
Solved in 2 steps
- For the planet Saturn,What is its average density (kg/m3)Expanding the gas in a container to five times its volume at a constant temperature results in a final gas pressure that is how many times the original. 0.2 5 0.5 20The material that holds the world record for being the least dense solid is silica aerogel, with a density of only 1 mg/cm3. What would be the mass of a cube of silica aerogel that measured 1 m on each side? Can you show me step by step how to do this? I know that Density=mass*volume
- The radius of Jupiter is about 69.0 x 103 km. The radius of the Sun is about 68.0 x 104 km. How many Jupiter volumes would fit inside the suns volume ?1. a. Derive the following expression for the fractional change in the speed of sound (dv/v) dv 1 dT related to a small change in temperature (dT): Start with the expression for the 2 T YRT M speed of sound related to temperature: v= where y is the ratio of heat capacities (a constant), R is the gas constant and M is the molar mass of the substance. Show enough steps (and words!) so that I can tell what you're doing. b. Use the red equation above to determine what the speed of sound in air at 21.0° C is, given that the speed of sound at 20.0° C is 344 m/s. Check your answer against any reference that has the speed of sound in air at different temperatures. Show your setup, and remember that the speed should not be terribly different! Hint: What temperature units should you be using?Learning Goal: To learn and practice the geometry skills necessary for complex reflection setups. The law of reflection has the very simple form Oreflected, Vincident = where incident is the angle between the normal and the incident ray and reflected is the angle between the normal and the reflected ray. Although the law itself is easy to use, many realistic situations involve successive reflections from multiple surfaces. The law of reflection does not become any more complicated in such cases, but the geometry of the rays does become complicated. Consider the case of light shining onto a mirror, which is attached to another mirror at some angle a, as shown in the figure (Figure 1). In this problem, we will find the angle at which light leaves the arrangement of two mirrors. Figure 1 of 2 > Part A If the light strikes the first mirror at an angle 0₁, what is the reflected angle 02? Express your answer in terms of 0₁. 0₂ = 0₁ Submit Part B Correct Previous Answers Now, find the angle…
