Answer:
theory
Explanation:
<em>A scientist can contribute to the formation of a theory in a particular subject by conducting research along the line of that subject.</em>
Conducting research requires the formation of a hypothesis and testing the hypothesis by conducting a relevant experiment during which data are gathered, analyzed, and interpreted in order to falsify or accept the hypothesis.
A good experiment must be replicate-able. When the same experiment is repeated by different independent researchers and the same conclusion is arrived at, this could potentially lead to the formation of a theory.
<u>Hence, a scientist can contribute to the formation of a theory by conducting an experiment with replicability in order to test a hypothesis.</u>
Answer:
his starting velocity was 18.297 ms⁻¹
Explanation:
v = u + at .................. (1)
Where
Final Velocity (v) = 0 ms⁻¹
Initial velocity (u) = ?
Acceleration (deceleration) (a) = -6.42 ms⁻²
time (t) = 2.85 s
Substituting all parameters into equation (1)
0 = u + (-6.42)2.85
0 = u + (-18.297)
0 = u - 18.297
18.297 = u
∴ the initial velocity was 18.297 ms⁻¹
