Answer:
Rectilinear lens
Explanation:
In photography, the distortions are caused in the formation of the image due to either the position of the camera or the optical design of the lenses i.e perspective and optical distortion.
The barrel distortion is a type of optical distortion caused due to the optical design of the lens. In barrel distortion, the straight lines of the light bend as a result of which the lines appear curved inwards in images.
The field of view of wider than the image sensor in barrel distortions which can be corrected by the use of rectilinear lens which provides straight lines without bending them. This lens stretches the image towards the edge and removes distortion.
Thus, Rectilinear lens is the correct answer.

Answer: d) B & C
Explanation: Variable substitution is the method through which the command substitution is done for the other form of command and regains its value or meaning.
This value substitution is done with the help of double quotes("...") which are inverted as well when a new form of command is to be introduced and it is known as back quotes. Other given options are incorrect because it is not determined in single quotes.Thus the correct option is option (d).
Answer:
Explanation:
Let's do this in python
(a) Between 5 and 60 and divisible by 5
for i in range(5, 60/5):
print(5*i)
(b) Less than 200 and divisible and 2 and 7
for i in range(1, int(200/14) + 1):
print(14*i)
(c)Sum of multiple of 8 that are between 100 and 500
sum_result = 0
for i in range(100, 500):
if i % 8 == 0:
sum_result += i
print(sum_result)
(d)sum of all odd numbers between 20 and 10
sum_odd = 0
for i in range(10, 20):
if i % 2 == 1:
sum_odd += i
print(sum_odd)
Errors in kernel mode (CPU running in ring 0) are usually fatal. This happens mostly inside device drivers.
