Answer:
Yes, the value of g affected by the radius.
Explanation:
The formula for the force of gravity of 2 objects is
, where m1 and m2 are the masses of the 2 objects, r is the radius, and G is the gravitational constant, which is approximately .
Therefore, as the radius if bigger, the force of gravity is going to be smaller exponentially.
Answer: Carbon dioxide is the primary greenhouse gas emitted through human activities. In 2019, accounted for about 80 percent of all U.S. greenhouse gas emissions from human activities. Carbon dioxide is naturally present in the atmosphere as part of the Earth's carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals. Human activities are altering the carbon cycle–both by adding more to the atmosphere, and by influencing the ability of natural sinks, like forests and soils, to remove and store from the atmosphere. While emissions come from a variety of natural sources, human-related emissions are responsible for the increase

Answer: The engine size
Explanation:
Explanatory variable is a type of independent variable, but it may not always be independent. It is varied to determine its effect on the response variable. In this case, to establish a relationship between gas mileage of cars and the engine size, one will want to predict the average gas mileage for various engine size. Therefore, the engine size is the explanatory variable while the gas mileage is the response variable.
Answer: The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
