<span><span>The more sources the better
Every researcher aims to have a standardized and uniform study when a study will be replicated or repeated for various reasons.
</span>The number of
accounts and evidential support of your thesis must be consistent and be
sufficient and succinct to the topic of study. These reasons and
evidential support should claim proximate with the pronounced
experimentation and variables which will be studied. In sense, the more
accounts and sources the better is your study, the greater it will stand
out and present itself. This is important for every thesis paper or
dissertation since these accounts provides and explicitly discusses the
studies that have been undertaken before which can greatly influence the
current study's credibility and reliability. </span>
Answer: A
Step-by-step explanation:
Algebraic (or numeric) expression (also referred to as phrase) A mathematical expression (numeric/algebraic) is one or a group of mathematical symbols representing a number or quantity. It may include numbers, variables, constants, operators, and grouping symbols. One side of an equation is also an expression.
This is an equation that calculates potential energy and converts the value into its commercial unit.
<u>Step-by-step explanation:</u>
Step 1:
Given equation is 2 kg × 9.81 m/s² × 40 m. From the units, find the corresponding measurements. kg is the unit of mass (m), 9.81 m/s² is the acceleration due to gravity (g) and m is the unit of length or height (h).
This shows that this equation is to find potential energy. It is then converted into the commercial unit of energy (Joules).
⇒ Potential Energy = mgh = 2 kg × 9.81 m/s² × 40 m
= 784.8 kg m²/s²
= 784.8 N-m (Since unit of force, 1 N=kg m/s²)
= 784.8 J (1 Newton-m = 1 Joule)
