<h3><u>Answer;</u></h3>
A. 4
<h3><u>Explanation;</u></h3>
- <em><u>The period of a wave or periodic time is the time taken for a complete oscillation to occur. </u></em>For example its is the time taken between two successive crests or troughs.
- <em><u>The beats or oscillation that occur in one second represents the frequency. Frequency is the number of complete oscillations or beats in one second in a wave.</u></em>
- Frequency, measured in Hertz is given by the reciprocal of the periodic time.
- Thus; <u><em>Frequency or beats per second = 1/(1/4) = 4</em></u>
- <u><em>Hence , 4 beats per second</em></u>
Answer:
Many logicians state that Aristotle produced the definitive work on logic and there is no sense of even changing it, although this has now changed. Nevertheless, his ideas of logic and ethics are now central to many philosophies that subsequently formed the foundations of Western ideals.
Explanation:
Newton's subsequent law expresses that power is corresponding to what exactly is needed for an object of consistent mass to change its speed. This is equivalent to that item's mass increased by its speed increase.
We use Newtons, kilograms, and meters each second squared as our default units, albeit any proper units for mass (grams, ounces, and so forth) or speed (miles each hour out of every second, millimeters per second², and so on) could unquestionably be utilized also - the estimation is the equivalent notwithstanding.
Hence, the appropriate answer will be 399,532.
Net Force = 399532

d) O
Explanation:
The relationship between entropy and the energy transferred is applied.
Mathematically, dS = dQ/T
the steps are as shown in the attachment.
<h2>Right answer: 8 m</h2><h2 />
When two waves propagate in the same medium, in the same or opposite direction, they <u>overlap (superposition</u>), that is, the individual waves are added producing a resultant wave. When the superposition of the waves occurs, they continue to advance after the encounter happens, conserving their properties, such as amplitude, frequency, wavelength and speed.
In this case, we have two water waves travelling in opposite directions with <u>differente amplitude</u>, when both waves encounter each other, at that moment the amplitude of the resultant wave is the sum of both, that is:
5m + 3m = 8 m
Therefore, the correct option is D
