Astudent designs an experiment where she will add varying amounts of sugar to a chemical reaction and then measure the mass of the chemicals produced during each reaction. the independent variable in this experiment is: a) the amount of sugar b) the mass of the chemical produced c) the temperature of the reaction d) the type of chemical reaction

A. The amount of sugar

A) The amount of sugar

Explanation:

The independent variable is the one which can be changed, altered or even manipulated manually so as to bring changes and alteration over the dependent variable. The dependent variable is the variable in which changes occur due to independent variable. It is the outcome of the experiment.

The amount of sugar is the correct option. This is because of the fact that amount of sugar can bring a change over the chemical reaction and mass of chemicals being produced.    

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
