Force = mass × acceleration
The best answer between the two options would be the second choice B) FALSE.
Answer:
C. The number of protons.
Explanation:
All atoms of mercury will remain the same while different isotopes may have different number of neutrons.
For example, mercury has 80 protons, correlating with its atomic number. However, the number of protons, neutrons, and electrons could vary between each atom. If there are 80 protons, then there has to be 80 electrons. This means that the protons have to be the same in order to apply to all atoms of mercury
Density = mass/volume. 5000/50= 100 grams per cubic centimeter. No substance on Earth has anywhere near that density. Tops is about 20 for osmium and gold.
Answer:
Graph B
Explanation:
This is because the full question is "The Earth has a speed of 108,064.5 km/hr around the sun. The planet Mars has a speed
of 86,868 km/hr around the sun. Which of the following graphs best represents the
motion of the two planets?" The answer would be B because the more steeper the slope means more speed.
