Answer:
c
Explanation:
A data graph has been attached to the given question which is of the year 2018.
According to it of 101.3 quad Btu total energy produced in USA, 11% is produced by renewable energy resources. that consists of 22% of from wind energy.
there amount of energy produced through wind is 22% of 11% of 101.3 quad Btu, which will be roughly about 2.5 quad Btu
Btu here is British thermal Unit.
hence option c is correct
Answer:
Answer explained below
Explanation:
The following is the nested if-else statement:
% if-based statement
if num < -2 || num > 4
f1(num)
else
if num <=2
if num >= 0
f2(num)
else
f3(num)
end
else
f4(num)
end
end
<u>NOTE:</u> the num is an integer variable that has been initialized and that there are functions f1, f2, f3 and f4.
The nested if-else statement can be replaced by switch statement as shown below:
switch num
case(0, 1, 2)
f2(num)
case(-2, -1)
f3(num)
case(3, 4)
f4(num)
otherwise
f1(num)
In this case, the switch based code is easier to write and understand because the cases are single valued or a few discrete values (not ranges of values)

Answer:
11.6 mm
Explanation:
With a factor of safety of 5 and a yield strength of 900 MPa the admissible stress is:
σadm = strength / fos
σadm = 900 / 5 = 180 MPa
The stress is the load divided by the section:
σ = P / A
σ = 4*P / (π*d^2)
Rearranging:
d^2 = 4*P / (π*σ)
