13
- B.
10
- C.
9
- D.
7
Correct Answer
B. 10Explanation
The metric system of measurement is based on the number 10. This is because the metric system uses a decimal system, where units are based on powers of 10. This makes conversions between units easier, as each unit is a multiple or fraction of 10. For example, there are 100 centimeters in a meter, 1000 meters in a kilometer, and so on. This system is widely used around the world and allows for consistency and simplicity in scientific and everyday measurements.Rate this question:

Mass and weight are different because...
- A.
Mass stays the same
- B.
Volume stays the same
- C.
Density stays the same
- D.
Weight stays the same
Correct Answer
A. Mass stays the sameExplanation
Mass and weight are different because mass is a measure of the amount of matter in an object and it remains constant regardless of the location or gravitational force acting on it. On the other hand, weight is the force exerted on an object due to gravity and can vary depending on the strength of the gravitational field. Therefore, even though the weight of an object may change in different locations, its mass will always remain the same.Rate this question:

The amount of space an object takes up is its what?
- A.
Place
- B.
Volume
- C.
Density
- D.
Height
Correct Answer
B. VolumeExplanation
Volume is the correct answer because it refers to the amount of space that an object occupies. It is a measurement of the three-dimensional size of an object and can be calculated by multiplying the length, width, and height of the object. Density is a measure of how much mass is contained within a given volume, and height is only one component of volume. Therefore, volume is the most appropriate term to describe the amount of space an object takes up.Rate this question:

- A.
Positive ion
- B.
Negative ion
Correct Answer
A. Positive ionExplanation
When an atom loses an electron, it becomes a positive ion. This is because the atom now has more protons than electrons, resulting in a net positive charge. The loss of an electron creates an imbalance in the atom's charge, causing it to become positively charged. Positive ions are attracted to negative ions or other atoms with a higher electron density, and they play important roles in chemical reactions and electrical conductivity.Rate this question:
