Unit seven lesson nine waves unit test, 30 questions Janelle wants to know how fast his skateboard can roll down the ramp in front of his school, so Janelle places the back of the skateboard, even with the top of the ramp, and times how long it takes before the front of the skateboard reaches the end of the ramp, and he reports the time he performs this procedure again for more times, and calculates the average time during this experiment Janelle demonstrates what is it renovation regeneration, replication, or replication

In this scenario, Janelle is conducting an experiment to measure the speed of his skateboard rolling down the ramp. He is timing how long it takes for the front of the skateboard to reach the end of the ramp and calculating the average time from multiple trials. This process does not involve renovation, regeneration, or replication. It is simply a measurement and calculation procedure to determine the speed of the skateboard.
