PLEASE ANSWER

Which example below would have the strongest gravitational force of attraction and why

A. Neither example would have a strong force of attraction.

B. Both objects would have the same amount of force pulling on them since they are the same size.

C. Example B would have the strongest force of attraction since the second object is larger.

D. Example A would have the strongest force between the two objects since they are the closest together.

D

Explanation:

gravitational force: F=GmM/r^2

so this equation tells you that when mass increases force increases and when the distance increases force decreases

since the mass of the objects is the same in both cases, but distance is greater in case B than case A, case B has a smaller attractive force compared to A

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
