Which of the following objects would take you the greatest amount of force to accelerate?

Complete question is;

Which of the following object would take you the greatest amount of force to accelerate.

A) a soccer ball with a mass of 0.5 kg

B) a refrigerator with a mass of 200 kg, C) a bike with a mass of 25 kg

D) a car with a mass of 5,000 kg,

D) a car with a mass of 5,000 kg

Explanation:

Formula for force is;

F = ma

Where;

F is force

m is mass

a is acceleration

Now, Force is directly proportional to the acceleration and mass.

Thus, the higher the mass, the greater the force.

Thus, the object that will require the most force is the one that has the highest mass.

Looking at the options, the one with the highest mass is option D.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
