[Q]: John wanted to invent a machine. To that end, he devised an experiment in which he used three components, comp A, comp B, and comp C. Comp A was a machine that applied force over a shorter distance. Comp B was also a machine, but it applied force over a longer distance. Comp C was not a machine. Would comp B increase or not increase the force applied compared to comp A?
****
[A]: not increase

[Q]: Justin is conducting a chemical experiment involving sodium hydroxide. A key part of the reaction is ensuring that the sodium hydroxide is dissolved in water before adding the other materials. Justin adds the sodium hydroxide to reaction A, and sets the heat to high. Justin can't use high heat for his second reaction, though, because the electricity supply is too weak to have both burners on high. Because of this, Justin adds the sodium hydroxide to reaction B and sets the heat to low. In which reaction will the sodium hydroxide dissolve slower?
****
[A]: reaction B
