Answer:

2 + 6 in programming is an example of math. It is the same as in the real world. Plus signs in coding are also a form of <em>string concatenaction,</em> the term used for combining two strings into one, or a variable into a string.
Advantages of technology in agriculture include expediting crop production rate and crop quantity, which in turn reduces costs of production for farmers and food costs for consumers, and even makes crops more nutritious and livestock bigger and meatier.
The excessive use of chemicals by the help of machines reduces the fertility of the land.Lack of practical knowledge the farmers cant handle the machines properly.While the cost of maintenance is very high.Overuse of machines may lead to environmental damage.It is efficient but has many side effects and drawbacks.
Answer:
19.9 pF
Explanation:
Given that:
Series connection :
11pF and 21pF
C1 = 11pF ; C2 = 21pF
Cseries = (C1*C2)/ C1 + C2
Cseries = (11 * 21) / (11 + 21)
Cseries = 7.21875 pF
C1 = 22pF ; C2 = 30pF
Cseries = (C1*C2)/ C1 + C2
Cseries = (22 * 30) / (22 + 30)
Cseries = 12.6923 pF
Equivalent capacitance is in parallel, thus,
7.21875pF + 12.6923 pF = 19.91105 pF
= 19.9 pF
The most necessary point you need to follow when using a line graph, is to make your graph readable. So, the reason why is it inportant to only graph 1 - 3 series of data is that more than 3 series of data causes too many lines on the graph, which makes ti confusing to read. The last option is the correct one.
