Explanation We know that law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. In any isolated system the total energy is constant. If there is a conversion of energy in the system from one form to another, the total energy before the conversion equals the total energy after the conversion. Now in our given question total energy before is equal to total energy after leaving the tap. We have two forms of energy kinetic energy and potential energy. According to law of conservation of energy sum of kinetic energy and potential energy is constant. E = K E + P E Now in our problem water starts from rest at a height h above the ground

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?
