Answer:</h2>
Deductive reasoning
<h2>
Explanation:</h2>
The process of using pre-existing knowledge to make logical conclusions, make predictions and draw out explanations is called reasoning. Reasoning are basically of two types:
i. Deductive reasoning: This takes a general rule, idea, or theory as foundation and then proceeds from there to draw meaningful conclusions or predictions. For example;
<em> If a = 3 ----------------(i)</em>
<em> And b = 5 ----------------(ii)</em>
<em> Then 2a + 4b = 26 -------------(iii)</em>
From above, following from equations (i) and (ii), it can be concluded that (iii) should be true.
ii. Inductive reasoning: While deductive reasoning moves from a general rule to specific rule, inductive reasoning does the opposite - moves from specific to a general rule.
Answer:
The beat frequency = 2.0 Hz
Explanation:
From the given information
The 3rd harmonic frequency of the note is equivalent to thrice note A fundamental frequency.
i.e.
where;
note A fundamental freq.
replacing 440 Hz for 
However, the 2nd harmonic of the E is equivalent to two times the fundamental frequency of the note E.
i.e.
note E fundamental freq.
replacing 659 Hz for 
Finally, the beat frequency when the E string is properly tuned is:
Thus, the beat frequency = 2.0 Hz
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as we now understand Earth's gravity pulls down anything that isn't held up by some other force
Answer:
To really help protect your eyes, a good pair of ultraviolet glasses will reduce the UV rays that reflect off the backside of your lenses by adding an antireflective (AR) coating that cut down the reflection of both UV and visible light.
