Answer:
the length of resultant vector is 5 inches
Explanation:
In the attachment, you will see X vector along the X axis and Y vector along the Y direction. Let the resultant vector be denoted by
The resultant vector always start from the tail of first vector and ends at the head of second vector.
Since it is a right angled triangle, so the result of resultant vector is found by using Pythagoras theorem i.e.
So, when we plug in the values of X = 48 and Y = 14
Therefore, the length of resultant vector is 5 inches.
Answer:
<em>a. all three resistors in parallel</em>
Explanation:
<u>Combination of Resistors</u>
The power supplied by a power source or V volts is:
where R is the equivalent resistance of the whole circuit connected to the power source.
As shown, the power is inversely proportional to R which means that if R is a minimum, P is a maximum.
The problem reduces now to find the combination of resistors that produces the least value of its equivalent. If three resistors are connected in series, the equivalent is the sum of all them
This equation gives R a value that is greater than the greatest of all three resistances.
If they are connected in parallel, the equivalent is given by
This equation produces for R a value that is smaller than the smallest value from the three resistances.
Any other combination of resistors will produce intermediate values between the maximum (series) and the minimum (parallel), thus:
a. all three resistors in parallel
<h2>Right answer: Doldrums</h2>
These are also called zones of equatorial calm and it is due a climatic phenomenon that is placed near the Earth equator, attributed to the soft winds, that are called calm winds as well; accompanied by systems of abundant rains and heat.
In this area periods of great calm occur when the winds virtually disappear completely, trapping the sailing ships for long periods (days or weeks). This is why the term <em>doldrum</em> became popular as a colloquial expression in the eighteenth century, to refer to "<em>the caprice of the wind that slows down the navigation to sail".
</em>
The zone is located in the place where two trade winds meet, this means the trade winds of the northern hemisphere <u>converge</u> with those of the southern hemisphere, that is why this region is related to the <u>intertropical convergence zone</u>.
Answer:84.405m,
Explanation:
Given
Person walk 42 miles due to north so its position vector is
Now he deviates to east and walk 65 miles
so its new position vector
So magnitude of acceleration is
for direction
