Answer:
R = 4.75 lb (↑)
Explanation:
Number of books = n = 19
Weight of each book = W = 1 lb
Length of the bookshelf = L = 40 inches
We can get the value of the distributed load as follows
q = n*W/L = 19*1 lb/ 40 inches = 0.475 lb/in
then the reactions at 4 ends (supports) of the bookshelf are
R = (q/2)/2 = 4.75 lb
We can see the bookshelf in the pic.
Answer:
month = input("Input the month (e.g. January, February etc.): ")
day = int(input("Input the day: "))
if month in ('January', 'February', 'March'):
season = 'winter'
elif month in ('April', 'May', 'June'):
season = 'spring'
elif month in ('July', 'August', 'September'):
season = 'summer'
else:
season = 'autumn'
if (month == 'March') and (day > 19):
season = 'spring'
elif (month == 'June') and (day > 20):
season = 'summer'
elif (month == 'September') and (day > 21):
season = 'autumn'
elif (month == 'December') and (day > 20):
season = 'winter'
print("Season is",season)

Answer:
0.5274 lagging.
Explanation:
So, we are given the following data or parameters or information which is what we need in order to solve this kind of question effectively. So, we have;
=> " For the given network:
ZR = 100 [Ω] , ZL = j124 [Ω], and ZC = - j89 [Ω]"
And we are asked to find the power factor. The power factor can be found or determined or calculated as;
7eq= 100 + j ( 24) (-89).
7eq = 124 × 89 - j89 × 100/ 100 + j35
7 eq= 133.81 L- 58.17.
Thus, the power factor is equal to;
=> Cos (58.17)= 0.5274 lagging.
Hence, the correct answer to this question is 0.5274 lagging.
