Which is an example of the gravitational force?

a. a basketball that was thrown in the air falls to the ground.
b. the particles that make up the neutrons in an oxygen atom are held together.
c. a radioactive element, uranium, decays and becomes stable.
d. the molecules that make up olive oil stick together.

Option (A) is the correct answer.

Explanation:

Force of gravity is defined as the force of attraction acted by the Earth or ground on objects with mass.

For example, when a basket ball is thrown into the air falls to the ground because force of gravity is pulling it towards itself.

Thus, we can conclude that a basketball that was thrown in the air falls to the ground.  

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
