Which of the following statements is true? a 15 kg box has more inertia than a 10 kg box. forces occur in equal and opposite force pairs. objects in motion will keep moving at the same velocity unless acted upon by an outside force. all of the above.

All of the above

Step-by-step explanation:

A 15 kg box has more inertia than a 10 kg box. --TRUE

Inertia is a property of matter related to its mass. The more mass an object has, the greater its inertia. S o the statement is correct since 15 kg is greater in mass than 10 kg therefore it has more inertia.

Forces occur in equal and opposite force pairs.  -- TRUE  

This statement is correct and is known as Newton's third law. Which tells us that for every force of action there is  a reaction force that is equal in magnitude but opposite in direction.

Objects in motion will keep moving at the same velocity unless acted upon by an outside force.  -- TRUE  

This is Newton's first law of motion, it tells us that an object will retain its state of rest or movement as long as there is no resulting force  or external force acting on it.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
