Answer:
I think its A. It accepted radiation in a chemical reaction, hope this helped.
If you were to cut the radium in half and have only 90 g, it will take up 18 cm³.

What is density?</h3>
The density of an object is the ratio of mass to volume of object.
Density = mass/volume
volume = mass/density
at a constant density, the volume of an object is proportional to its mass.
From the question, you have 180 g of radium that takes up 36 cm ^ 3 of space if you were to cut it in half and have only 90 g, the new mass will take the following volume.
180 g = 36 cm³
90 g = ?
= (90 x 36) / 180
= 18 cm³
Thus, if you were to cut the radium in half and have only 90 g, it will take up 18 cm³.

That force would be gravity. Gravity is what pulls any object down towards Earth due to the large mass of the Earth.
