Answer:
<h3>Heyy mate!</h3>
Explanation:
- (i) The gravitational force between two objects is directly proportional to the product of masses of the two objects. So, if the mass of one of the objects is doubled, then the force also gets doubled (it becomes 2 times).
- If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
- The distance between the objects is doubled and tripled
- Force thus becomes one-fourth of its initial force. Force thus becomes one-ninth of its initial force.
- Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. ... If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Answer:
Climate change is partly the result of an increased concentration of greenhouse gases, especially carbon dioxide
Explanation:
Increased concentration of carbon dioxide, leads to change in temperature because it traps the heat in the Earth's atmosphere. For greenhouse, carbon dioxide is the main gas. The other green house gases are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Absence of the greenhouse leads to the average temperature of about -18 degree Celsius. But when these gases are present the average temperature is about 15 degree Celsius.
