This question is a bit ambiguous because all parts of a scientific argument must be supported by valid data. However, among the choices, the closest synonym to "valid data" would be evidence. Evidence is the body of facts or information that support a given idea.
This is a poorly written question.
<span>Out of the choices listed, the first one is the only one that includes
a true statement ... the greater the mass of two objects, the
greater
the gravitational attraction is between them.</span>
-- Newton's law of universal gravitation doesn't "suggest" that. It states it ...
boldly and unequivocally.
-- The law doesn't refer to the "greatness" of the mass of the two objects.
It refers to the product of their masses.
-- It's true that the law of universal gravitation can be massaged and
manipulated to reveal the existence of gravitational planetary orbits.
But there's a lot more to it than simply the masses.
For example ... the gravitational force between two objects is inversely
proportional to
(the distance between the objects)² .
It turns out that IF that exponent were not precisely, exactly 2.000000... ,
then gravitational orbits could not exist.
Answer:
The circumference of the bromine atom is 628 pm
Explanation:
The formula for the circumference of a circle is 2πr.
Where π is 3.14 and r is the radius of the circle.
Since atoms have a circular shape. The formula above can be used to determine the circumference of an atom (bromine atom in particular).
circumference of the bromine atom is 2πr (where r is 100 pm)
2 × 3.14 × 100 = 628 pm.
The circumference of the bromine atom is 628 pm
