63. The interference fringes for sodium light (λ = 5890 A°) in a double slit experiment have an angular width of 0.2°. For what wavelength will the width be 10% greater?

Correct Answer: (3)6479 A°
Solution:(3) Angular width of fringes

in an interference pattern is

given by:

λ₂= 6479

And, the increase in wavelength = 6479-5890 = 589 angstroms

64. Blue Revolution is related to

Correct Answer: (4) Fisheries
Solution:(4) Blue Revolution is the water equivalent of the green revolution and primarily refers to the management of water resources, especially fish production.

Solution:(2) Weather refers to the state of the atmosphere at a given time and place, with respect to variables such as temperature, moisture, wind velocity, and barometric pressure. Weather describes the condition of the atmosphere over a short period of time e.g. from day to day or week to week, while climate describes average conditions over a longer period of time.

66. What is the output of this program?

int main() {
char arr[20];
int i;
for (i = 0; i < 10; i++)
.(arr + i) = 65 + i;
.(arr + i) = '\0';
cout << arr;
return 0;
}

Correct Answer: (1) ABCDEFGHIJ
Solution:(1) Each time we are assigning 65+ i. In first iteration i = 0 and 65 is assigned. So it will print from A to J
$ g++ point1.cpp
$ a.out
So, the correct output will be
ABCDEFGHIJ

67. Coefficients of variation of two distributions are 50 and 60 and their arithmetic means are 30 and 25 respectively. Difference of their standard deviations is

Correct Answer: (2) 0
Solution:

(2) Here, CV₁ = 50, CV₂ = 60,
      x̄₁ = 30, x̄₂ = 25

∴ CV₁ = (σ₁ / x̄₁) × 100

⇒ 50 = (σ₁ / 30) × 100

⇒ σ₁ = (30 × 50) / 100 = 15

and CV₂ = (σ₂ / x₂) × 100

⇒ 60 = (σ₂ / 25) × 100

⇒ σ₂ = (60 × 25) / 100 = 15

∴ σ₁ - σ₂ = 15 - 15 = 0
