Answer 2

An indicator shows a solution's pH by changing its color depending on its acidity. Thus, the answer is option A.

A pH indicator is a device used to check whether a chemical solution is acidic or alkaline. It ranges from a scale 1 to 14. 1 being the most acidic and 14 being the most alkaline. 7 shows a neutral stage. The color of scale number 1 is red and the color of scale number 14 is purple.

It changes color due to the disassociation of H++ ions.

By adding tape to his BAAD, Cramwood increased its mass and increased

its inertia. The bigger BAAD requires more force to stop and ends up smacking Cramwood in the head when he applies the brakes.

What is inertia?

Inertia is the tendency of an object to resist a change in its motion. Specifically, it is the property of matter that causes an object to maintain its state of rest or uniform motion in a straight line unless acted upon by an external force.

In other words, an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line, unless acted upon by an external force.

The amount of inertia an object has depends on its mass, with more massive objects having more inertia than less massive objects.
