Divergent, convergent and transform
Answer:
=1.068 ×10⁻¹³N
Explanation:
Force of gravity =Gm₁m₁/d² where G is the universal gravitation constant =G = 6.673 x 10-11 N m²/kg², m₁ and m₂ is the mass of object 1 and 2 respectively and d is the distance between them. First we change the distance into SI units i.e meters 25 km= 25000 m
F= (6.673 x 10⁻¹¹ N m²/kg²×1000 kg×1000 kg)/ (25000 m)²
=1.068 ×10⁻¹³N
The least amount of energy required to activate atoms or molecules to a state in which they can undergo a chemical reaction.
Answer:
- <u><em>B. Negative association</em></u>
<u><em></em></u>
Explanation:
<em>Negative association</em> is when the independent and dependent variables move in opposite directions: if the dependent variable increases, the independent variable decreases, and if the dependent variable decreases, the independent variable increases.
As you see in the diagram, as you move to the right on the horizontal axis, meaning that the independent variable is increasing, the points lie lower, meaning that the independent variable decreases.
Therefore, if you draw a line of best fit, it will have a negative slope. A negative slope indicates <em>negative association.</em>
The graph certainly shows association as there is a clear trend; else the points would be randomly dispersded.
