The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. what is the average acceleration of the car? a. 3.75 meters/second b. 3.75 meters/second2 c. 0.27 meters/second2 d. 0.27 meters/second

B. 3.75 meters/second2

Explanation:

The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. What is the average acceleration of the car;

acceleration = (change in velocity)/(change in time)

acceleration = ( 30 - 0)/(8)

acceleration = 3.75 meters/second2

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!
