The question is incomplete, the complete question is;
Shah did not trust the results of an experiment that she had read about, so she is conducting the experiment herself. She goes through the same set of steps and measures the effect of the amount of sugar on a single organism.
Which best describes what Shah is doing?
replication
repetition
both repetition and replication
neither repetition nor replication
Answer:
replication
Explanation:
Replication in scientific experiments refer to the process of going through all the steps in an experiment in order to obtain the same set of results initially obtained.
All scientific experiments is expected to be replicated under identical experimental conditions. If the results obtained by a scientific investigation cannot be replicated under identical circumstances by other scientists, then the scientific data must be taken with a pinch of salt.
Shah is expected to obtain almost exactly the same data as the original researchers who first published the data.
Answer:
A) was reusable
Explanation:

Velocity is distance over time
. If it wants it in km/h you're good to go otherwise if its m/s you need to convert km to m by multiplying 30 by 1000 and t in hours to seconds by multiplying 0.5 by 3600.
As we know that gravitational potential energy is given by
here we have
m = mass = 120 kg
h = height = 8.2 m
now from above formula
so above is the gravitational potential energy of the couch
