When an object moves in a straight line, which statement is true?  A. the object moves at a constant speed, the resultant force is zero

B. the object accelerates , the resultant force is zero

C. the object moves at a constant speed, the forward force is greater than the resistive force

D. The object requires a resultant force in order to move at a constant speed

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!

i think the answer is a and b

i wish you luck
