That gives you the magnitude of velocity, but it doesn't handle
the directions that are involved.
Answer: The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.
Explanation:
Answer:
v = 24.5 m
Explanation:
Average speed is defined as
v = (
- x₀) / t
The distance is
x = v t
In this case we can find the speed
v = (v_nort ¾ t + v_sud ¼ t) / t
v = 45 ¾ - 37 ¼
v = 24.5 m
Answer:
contour lines
Explanation:
Contour lines is a map feature which help to indicate region of equal height in a map.
In a map, contour lines are usually drawn in irregular circles repeatedly, until the elevations of the region are fully represented.
The inner part of the contour lines usually denote high elevation while the outter contour lines usually denote lower elevation.
Therefore the map feature that best indicates whether two regions have the same elevation is contour lines.
