Which one of the following is not a step in the inquiry process
a. investigate
b. classify
c. summarize
d. observe

(B) Classify

Explanation:

 The classify is not the part of the inquiry process as the inquiry process are basically based on the different types of observations and then summarize it properly after the investigation. Without any observation we cannot classifying the specific things.

The inquiry is the process that include investigation planning and making the proper observation about the incident.

Then, collect all the related information and summarize all the process. It also include analyzing process, interpretation of the data and reviewing process.

Therefore, option (B) is correct.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
