Answer:
Physical properties of mercury are described here.
Explanation:
Mercury is a metal. Mercury is the only metal which is liquid at room temperature. Mercury is shiny silver in liquid form. It has a melting point of -38.9 degree Celsius and a boiling point of 356.7 degree Celsius. The symbol of mercury is Hg and it has an atomic number, 80 and atomic weight of 200.59. Mercury is a poor conductor of heat and good conductor of electricity. Mercury is considered a heavy metal.
In this question, its liquid form, and the volume of the mercury grows as temperature rises, are the examples of physical properties of the mercury.
Answer:
1. (x-4), (y+4)
2. In a transformation, the equation shows how much the original coordinate moves. In the equation above, the orignal coordinate would move to the left 4 places, and then up 4 places. This particular transformation is called a translation, as the shape is the same but only in a different spot.
3. Quadrilateral
4. The transformed polygon has the apostrophes after each letter, which means it is "prime" or not the original.
Explanation:
1. To write the equation, look at how the shape shifts. If the x coordinate moved 4 spaces to the left, then that means the equation is -4. Do the same for the y-coordinate, except keep in mind it is up and down instead of left or right.
2. The answer is self-explanatory.
3. A quadrilateral has 4 sides, and this can be applied to more specific shapes, such as a square or rectangle. Because this shape has no distinctive features, it is safest to call it a quadrilateral.
4. The answer is self-explanatory.
Answer:
A
Explanation:
The physical environment has a massive effect on human activities. Throughout history the impact of the effect of the physical environment has changed, but the influence has always been there. Some ways in which the physical environment affect humans are:
- weather and climate
- natural disasters (volcanic eruptions, earthquakes, tsunamis)
- terrain
Human activities also have a significant impact on the physical environment. Some examples of ways that humans affect the physical environment are:
- deforestation
- extraction of resources
- anthropogenic climate change
- modification of topography
- contamination of the seas
8. B
9. D
10. C
11. A
12. (called the polor front but there are only 4 definitions??)
Is that a stament or question?
