Explanation

Tetanus spores, found in soil and dust, enter the body through deep wounds or punctures.

In such low-oxygen environments, the bacteria produce toxins that affect muscles and nerves.

Explanation

The formula for the interior angle of a regular polygon is (180° × (n - 2)) / n, where n = 5 for a pentagon.

Substituting n = 5, we get (180 × 3) / 5 = 108° per angle.

Explanation

Laser amplification involves increasing light intensity through stimulated emission inside a resonant optical cavity.

The resonance causes photons to bounce back and forth, stimulating more emissions and amplifying the light.

Explanation

To find the area of the border, let's first find the area of the entire rectangle and the area of the inner rectangle.

Area of entire rectangle = Length × Width

= 20 × 10

= 200 cm²

The inner rectangle's dimensions are:

Length = 20 - 2 × 2 = 16 cm

Width = 10 - 2 × 2 = 6 cm

Area of inner rectangle = 16 × 6

= 96 cm²

Area of border = Area of entire rectangle - Area of inner rectangle

= 200 - 96

= 104 cm²

Explanation

Formal drama involves scripted performances where students follow written texts.

It is controlled by the teacher, with little room for spontaneity.

Explanation

The formula for the perimeter of an equilateral triangle is P = 3 × side.

Given P = 15 cm, solving 15 ÷ 3 = 5 cm.

Explanation

Fathom means سمجھو

Comprehend means سمجھو

Explanation

Since it's a square garden, all sides are equal. To find the length of one side, take the square root of the area:

√2704 m² = 52 m

Explanation

Given an = n²:

a13 = 13² = 169

a20 = 20² = 400

The sum of the 13th and 20th term is:

169 + 400 = 569

Explanation

gets() can accept a full string including white space characters until a newline is encountered.

In contrast, getch() and getche() only accept a single character input.
