Answer 1

Answer:

In physics and chemistry, ionization energy or ionisation energy, is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule.

Answer 2

Step-by-step explanation:

AnSwEr :-

2 or -6.

Given :-

The distance between the points A(2, -2) and B(-1, x) is equal to 5.

To Find :-

Value of x

SoluTion :-

Here,

x1 = 2

y1 = -2

x2 = -1

y2 = x

Formula for finding distance between two points is :-

\sqrt{{(x2 - x1) {}^{2} } + (y2 - y1) {}^{2} }

(x2−x1)

2

+(y2−y1)

2

Put the values in the formula :-

√ (- 1 - 2)² + {x - (-2)}² = 5

→ √ { (-3)² + (x + 2)² } = 5

→ √{ 9 + (x + 2)² } = 5

→ 9 + (x + 2)² = 25

→ (x + 2)² = 16

→ x + 2 = ± 4

_____________________

x + 2 = 4

→ x = 4 - 2

→ x = 2

_____________________

x + 2 = - 4

→ x = - 4 - 2

→ x = - 6

Hence, the value of x is 2 or -6.
