Which helps identify the law of gravity as a law? In his experiments at the Tower of Pisa, Galileo found that gravity accelerates all objects at the same rate.
It states that gravity is a force of attraction that exists between any two objects in the universe.
It is based on scientific observations made by several different scientists over hundredths of years.
It explains how the masses of two objects and the distance between them determine the exact amount of the fom

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

b is the correct answer

mark me brainliest and hope this

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
