The statement "The burning bag smelled similar to rotten eggs."represents an example of observation.
-
True
-
False
Correct Answer
A. TrueExplanation
The statement "The burning bag smelled similar to rotten eggs" represents an example of observation because it describes a sensory experience (smelling) and compares it to a familiar smell (rotten eggs). Observations are made through our senses and provide information about the world around us. In this case, the observation is about the smell of a burning bag.Rate this question:

What is the choice that could better correspond to the following number expressed in scientific notation and rounded to the nearest hundredth?
-
0.04928
-
4.9280
-
0.004928
-
0.4928
Correct Answer
A. 0.004928Explanation
The number given in scientific notation is 0.004928. To round this number to the nearest hundredth, we look at the digit in the thousandth place, which is 9. Since 9 is greater than or equal to 5, we round up. Therefore, the correct choice is 0.004928.Rate this question:

How are science and technology related?
-
They are completely independent.
-
They are interdependent, meaning that advances in one lead to advances in the other.
-
They are dependent since science cannot develop without feedbacks from technology.
-
None the choices above.
Correct Answer
A. They are interdependent, meaning that advances in one lead to advances in the other.Explanation
Science and technology are interdependent because advancements in one field often contribute to advancements in the other. Scientific discoveries and theories provide the foundation for technological innovations, while technology enables scientists to conduct experiments, gather data, and analyze information more efficiently. The two fields work hand in hand, with scientific research driving technological development and technology providing tools and resources to further scientific exploration. This symbiotic relationship between science and technology leads to continuous progress and advancements in both areas.Rate this question:

Correct Answer
A. ChemistryExplanation
Chemistry is the study of the composition, structure, properties, and reactions of matter. It explores the behavior of atoms and molecules and their interactions with each other. When a paper burns, it undergoes a chemical reaction called combustion. Chemistry explains that combustion is a rapid oxidation process in which the paper reacts with oxygen in the air, breaking down its molecular structure and releasing energy in the form of heat and light. Thus, chemistry provides the understanding of why burning a paper turns it into ashes.Rate this question:

Which of the following would best suit data that describe how a part relates to the whole?
-
Line graph
-
Circle graph
-
Scientific Notation
-
Bar graph
Correct Answer
A. Circle graphExplanation
A circle graph, also known as a pie chart, would best suit data that describe how a part relates to the whole. This type of graph visually represents the proportions of different parts or categories in relation to the whole by dividing a circle into sectors. Each sector represents a specific part or category, and its size is proportional to the value it represents. This allows for easy comparison of the parts and their relationship to the whole, making it an effective choice for displaying this type of data.Rate this question:

The choice that best corresponds to the conversion of 10 degrees celsius into degrees fahrenheit is: Given:
-
25
-
50
-
30.5
-
55.8
Correct Answer
A. 50Explanation
To convert Celsius to Fahrenheit, you can use the formula: F = (C × 9/5) + 32. Plugging in 10 degrees Celsius into the formula, we get: F = (10 × 9/5) + 32 = 18 + 32 = 50. Therefore, the correct answer is 50 degrees Fahrenheit.Rate this question:

The statement "It might have rained last night since the floor is wet." represents an example of inference
-
True
-
False
Correct Answer
A. TrueExplanation
The statement "It might have rained last night since the floor is wet" represents an example of inference because it is based on reasoning and drawing a conclusion from available evidence. In this case, the evidence is the wet floor, and the inference is that it might have rained.Rate this question:
