PLEASE HELP Fossil fuels (oil, coal, and natural gas) provide us with much of the energy that allows us to drive a car, heat and cool our houses, cook food, watch television, and more. Despite many people’s concerns about the use of fossil fuels, other energy sources are not used very much.

Which energy source do you think is the best alternative and why?

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

Which component is used to measure the current in a circuit? oa. switch ob. resistor oc. ammeter the answer is c. for y’all plato people

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
