Answer:
Explanation:
Saturn orbital period
p(s)= 29.46years
Average distance
a(s) = 9.54AU
Venus orbital period
p(v) = 0.62 years
a(v) ?
Using Kepler's third law
a³ ∝p²
a³ = kp²
a³/p² = k
Where
a is the distance if planet from sun
T is the period of the planet
Then,
a(Venus)³/p(venus)² = a(saturn)³/p(saturn)²
a(v)³/p(v)² = a(s)³/p(s)²
a(v) ³/ 0.62² = 9.54³/29.46²
a(v) ³/ 0.62² = 1.0004
a(v)³ = 1.0004× 0.62²
a(v)³ = 0.3846
a(v) = cube root(0.3846)
a(v) = 0.727 AU
The best way would be to test groups of each kind of fabric by exposing them to the same amount of water for the same amount of time. The correct option is A.
<h3>Scientific experiments</h3>
In conducting scientific experiments to compare test subjects such as the fabrics mentioned in the illustration, the test subjects must be subjected to the same conditions.
The outcome of the experiment will no longer be scientifically valid if the test subjects are not exposed to the same condition.
Thus, the two fabrics must be exposed to the same amount of water for the same amount of time in order to come to a valid conclusion about which is a better water repeller among the two.

We’ve all noticed that science has been accelerating and a very fast rate resulting in what has been called information overload and more recently filter failure. There are now more researchers add more papers than ever which has led to the importance of bibliometric measures Bibliometric as a Field is a fairly new discipline but it has seen in impressive growth in years due to computation and data storage. Journal metrics can play an important role for editors. There are many different metrics
