C. Inductive reasoning
D. Procedure
Answer;
A. Bias
If the personal opinion of a scientist affects the way that the experimental results are reported, that is called bias.
Explanation;
-An experimenter bias, is a process where the scientists performing the research influence the results, in order to portray a certain outcome.
-Bias is among the factors that makes a qualitative research much more dependent upon experience and judgment than quantitative research.
-Bias in a research may arise from experimental errors and failure to consider all the possible variables and also when the researchers select the subjects that are more likely to generate the desired results.
Answer:
The correct answer is option b, that is, when the Sun, Earth, and the moon are nearly in a line.
Explanation:
The low and high tides are caused by the moon. The gravitational force of the moon produces something known as the tidal force. This force makes the Earth and its water to bulge out on the side nearest to the moon and the side far away from the moon. These bulges of water are considered as high tides.
Similarly to the moon, the Sun also causes tides, but, they are smaller in comparison. However, when the Earth, moon, and the Sun line up, that is, which takes place during the new moon or the full moon, the solar and lunar tides reinforce each other, resulting in more extreme tides, known as spring tides. The spring tides are considered as the highest tides.
A.5.3
B.4.7
C.8.7
D.9.3
The correct answer is C) 8.7
The pH of a solution indicates the acidity or basicity of the answer. A solution is said to be neutral if the pH is 7, if the pH fee is less than 7 then it is acidic in nature and if the pH cost is greater than 7 then the solution is simple in nature.
Ph may appear as it belongs at the periodic desk of factors, however, it's truly a unit of size. The abbreviation pH stands for ability hydrogen, and it tells us how an awful lot hydrogen is in drinks—and the way active the hydrogen ion is.
PH is a measure of the attention of H+(aq) ions in an answer. The attention of H+ ions may be stated in mol dm(-three), but the use of the log(10) feature simplifies the numbers concerned. Definition: pH is the terrible logarithm to base 10 of the hydrogen ion awareness in an aqueous solution.
