Answer:
IF the fruit juice contains a high level of vitamin C, THEN the preventative effectiveness against common cold increases.
Explanation:
The hypothesis is a testable explanation of a scientific investigation. It aims at predicting the outcome of the experiment. One feature of the hypothesis is that it must be testable. The hypothesis is usually written in an "IF, THEN" format.
This question is regarding an experiment to test the amount of vitamin C in fruit juice. The vitamin C is thought to be an effective preventative against common cold. Hence, the hypothesis connects the effect on common cold (dependent variable) with the amount of vitamin C (independent variable). The hypothesis can be written as:
IF the fruit juice contains a high level of vitamin C, THEN the preventative effectiveness against common cold increases.
<span>The formula for mass, which is mass = density x volume, can be rewritten as volume = mass/density. We can deduce the volume of the cube as the mass and density are given: 17.2g/2.7g/ml = 6.37ml. Now that the volume of the cube is known, we can deduce the edge length. Volume = length x width x height, so 6.37 = X^3. We then take the cube root of 6.37 to discover the value of x, which will be the edge length of the cube. The edge length of the cube is 1.85 cm.</span>
To find the density, the formula would be d= m/V. Your answer would be 19.9 or if you round, 20.
