Answer:
C.) T = 1.20s
Explanation:
From equation of motion,
S = ut + ½gt²
S = 7m
g = 9.8m/s²
U = 0m/s (since he starts from rest)
t = ?
S = ut + ½gt²
7 = 0 * t + ½ * 9.8 * t²
7 = 0 + 4.9t²
t² = 7 / 4.9
t² = 1.42857
t = √(1.42857)
t = 1.195s
t = 1.20s
If you increase the number of trials in an experiment it will make the test more valid and legitimate.As you take the same test/experiment once or twice you could see if your results are similar to each other.
Nearly everything in science is considered a "theory" because there isn't enough evidence to prove it to be a fact. So,if more evidence is discovered,a theory will become a fact,or if evidence is discovered disproving a theory,the theory is no longer even valid as a theory.
