Answer:
1. Newton believed that gravity was a force.
3. The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Explanation:
Law of gravitation states that force is directly proportional to masses of objects and inversely proportional to the distance between from their center. Directly means if mass increases, force of attraction also increased while inversely means if distance decrease between objects, force of attraction is also increased. Gravity is measured in weight because weight ia a force which attracts things towards its center.
B) Primary is where there is nothing no rock or soil
Answer:
Starch + H2O = maltose
