An object is moving across a surface, but it does not gain or lose speed. Which best describes the object’s force? The net force is positive.
The net force is zero.
The positive force is greater than the negative force.
The negative force is greater than the positive force.

An object is moving across a surface, but it does not gain or lose speed, the object's net force is zero.

Explanation: The net force means the vector sum of all the forces acting on an object

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
