Solution: Approximately 10 times.

Explanation of Solution

  Essential Cosmic Perspective, The, Books a la Carte Edition (8th Edition), Chapter 14, Problem 1VSC

The y axis in the plot is in logarithmic scale. Hence, the peak brightness of massive supernova is around 2×109 solar units, while the peak bright ness of white dwarfs is about 1×1010 solar units. Hence, the brightness of white dwarf supernova is approximately 10 times brighter than the massive star supernova.

Conclusion: The white dwarf supernova is 10 times brighter than massive star supernova.

What is the error determined by the 2/3 rule?
Your colleague gives you a sample that are supposed to consist of Pt-Ni nanoparticles, TiO2 nanorod arrays, and SiO2 monolith plates (see right panel schematic). The bimetallic Pt-Ni nanoparticles are expected to decorate on the side surfaces of the aligned TiO2 nanorod arrays. These aligned TiO2 nanoarrays grew on the flat SiO2 monolith. Let's assume that the sizes of the Pt-Ni nanoparticles are > 10 nm. We further assume that you have access to a modern SEM that can produce a probe size as small as 1 nm with a current as high as 1 nA. You are not expected to damage/destroy the sample. Hint: keep your answers concise and to the point. TiO₂ Nanorods SiO, monolith a) What do you plan to do if your colleague wants to know if the Pt and Ni formed uniform alloy nanoparticles? (5 points) b) If your colleague wants to know the spatial distribution of the PtNi nanoparticles with respect to the TiO2 nanoarrays, how do you accomplish such a goal? (5 points) c) Based on the experimental results…
