Probably because they think it is more accurate.
Hope it helps.
Answer:
6. Scientific inquiry - D
7. Hypothesis - E
8. Control group - G
9. Experimental group - A
10. Independent variable - B
11. Dependent variable - H
12. Scientific theory - C
13. Scientific law - F
Explanation:
6. Scientific inquiry - D
Scientific inquiry is the study of the explanation for the natural world phenomenon and it requires many scientific steps.
7. Hypothesis - E
A hypothesis is a possible explanation for a phenomenon or problem. It is tested in order to see if true or not.
8. Control group - G
The control group in a scientific experiment is a group of subjects did not get the treatment and left alone.
9. Experimental group - A
The experimental group is another hand group of subjects that gets treatment and shows the effect of the variable being tested.
10. Independent variable - B
Independent variables change or manipulated during an experiment and cause a response from the dependent variable.
11. Dependent variable - H
The dependent variable is a variable that is dependent on independent variables and changes in the independent variable.
12. Scientific theory - C
A well-tested explanation for experimental results with the scientific process.
13. Scientific law - F
This describes an observed pattern in nature
The energy will be transferred from the warmer object to the freezing object .
Answer:
groups
Explanation:
periods are left and right groups are up and down
<u>Answer</u>:
Changing direction is an example of a kind of acceleration
<u>Explanation</u>:
Acceleration is the "change of velocity" of an object concerning time. Acceleration being vector quantities, thus an object’s acceleration is the produce of orientation of the net force that has been acted on the object.
Newton’s second law explains the magnitude of acceleration. An example is when a car travels in the straight line, it is accelerates in the direction of its travel. As the car turns the acceleration occurs in a new direction.
