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.
The given statement is true.
Explanation:
Research work needs to be conducted in some particular, well-organized processes. This systematic process aims at gathering ample of information to reach a conclusion by the researcher.
It includes-
(i) identification of a problem to raise a question on that;
(ii) reviewing that problem and learning all about it;
(iii) clarification of the problem is needed which make the scope of study narrow;
(iv) defining the concepts and terms of the research;
(v) studying a particular group which is the objective of the research; (v) The methods and participation is reviewed;
(vi) Collection of data is needed;
(vii) analyzing the data is the last step.
There would be an increase in "Zebra" and "Gazelle" population. This is due to the fact that there wouldn't be as many lions to eat the zebras and gazelles, causing their repopulation to become more frequent.
