1100 grams because you have to add the grams of both the substances, and because they are liquid they dont cancel out. 1000+100= 1100 grams
Answer:
D. One dependent variable and one experimental variable
Explanation:
The experimental variable is defined as an independent variable which can be manipulated during an experiment in order to find out its impact or influence on the dependent variable.
The dependent variable refers to a variable that changes when an experimental or independent variable is manipulated.
Every experiment must have at least one experimental variable and one dependent variable in order to yield any meaningful result.
Answer:
not sure, but you know what?
Explanation:
you are amazing! keep doing what youre doing!
A curved line or surface cannot be measured by a straight scale, a measuring tape or thread must be used instead.To measure a curved line using a thread, follow the below steps:
Tie a knot at one end of the thread.
Place the thread at the beginning of the line and try to measure a small initial portion of the line which is relatively straight.
Place your thumb at the other end of the measured portion and measure next straighter portion.
Repeat the above step till the end of line is reached. Make a knot at the end of the line.
Now, straighten the thread and measure the length of the two knots on a scale.
To convert 390 ml to grams, besides the volume we have to know the substance’s density ρ in g/cm3<span> or in any other unit. Alternatively, when we know the material, then we can look for its density in a search engine. As explained on our home page, 390 ml equal 390 cm</span>3<span>, and as also outlined there, in common use the equation for water is 390 milliliter = 390 g</span>
