№8.23 (с. 44)
Условие. №8.23 (с. 44)
скриншот условия
8.23 В физике для измерения кинетической энергии часто используется не джоуль (Дж), а электрон-вольт (эВ), $1 \text{ эВ} = 1,6 \cdot 10^{-19} \text{ Дж}$. Выразите в джоулях значения энергий, достигнутых на современных ускорителях: 250 МэВ, 10 ГэВ, 200 ГэВ, 1 ТэВ, 14 ТэВ.
Решение. №8.23 (с. 44)
Дано:
$E_1 = 250 \text{ МэВ}$
$E_2 = 10 \text{ ГэВ}$
$E_3 = 200 \text{ ГэВ}$
$E_4 = 1 \text{ ТэВ}$
$E_5 = 14 \text{ ТэВ}$
Соотношение между электрон-вольтом и джоулем:
$1 \text{ эВ} = 1.6 \cdot 10^{-19} \text{ Дж}$
Приставки СИ:
Мега (М) - $10^6$
Гига (Г) - $10^9$
Тера (Т) - $10^{12}$
Найти:
Выразить значения энергий $E_1, E_2, E_3, E_4, E_5$ в джоулях (Дж).
Решение:
Для перевода значений энергии из электрон-вольт (с соответствующими приставками) в джоули, необходимо сначала учесть множитель приставки, а затем умножить полученное значение в электрон-вольтах на коэффициент перевода $1.6 \cdot 10^{-19} \text{ Дж/эВ}$.
250 МэВ
Сначала переведем мегаэлектрон-вольты в электрон-вольты:
$E_1 = 250 \text{ МэВ} = 250 \cdot 10^6 \text{ эВ}$
Теперь переведем в джоули:
$E_1 = 250 \cdot 10^6 \cdot 1.6 \cdot 10^{-19} \text{ Дж} = (250 \cdot 1.6) \cdot (10^6 \cdot 10^{-19}) \text{ Дж} = 400 \cdot 10^{-13} \text{ Дж} = 4 \cdot 10^2 \cdot 10^{-13} \text{ Дж} = 4 \cdot 10^{-11} \text{ Дж}$
Ответ: $4 \cdot 10^{-11} \text{ Дж}$.
10 ГэВ
Переведем гигаэлектрон-вольты в электрон-вольты:
$E_2 = 10 \text{ ГэВ} = 10 \cdot 10^9 \text{ эВ} = 10^{10} \text{ эВ}$
Теперь переведем в джоули:
$E_2 = 10^{10} \cdot 1.6 \cdot 10^{-19} \text{ Дж} = 1.6 \cdot 10^{(10-19)} \text{ Дж} = 1.6 \cdot 10^{-9} \text{ Дж}$
Ответ: $1.6 \cdot 10^{-9} \text{ Дж}$.
200 ГэВ
Переведем гигаэлектрон-вольты в электрон-вольты:
$E_3 = 200 \text{ ГэВ} = 200 \cdot 10^9 \text{ эВ} = 2 \cdot 10^{11} \text{ эВ}$
Теперь переведем в джоули:
$E_3 = 2 \cdot 10^{11} \cdot 1.6 \cdot 10^{-19} \text{ Дж} = (2 \cdot 1.6) \cdot (10^{11} \cdot 10^{-19}) \text{ Дж} = 3.2 \cdot 10^{-8} \text{ Дж}$
Ответ: $3.2 \cdot 10^{-8} \text{ Дж}$.
1 ТэВ
Переведем тераэлектрон-вольты в электрон-вольты:
$E_4 = 1 \text{ ТэВ} = 1 \cdot 10^{12} \text{ эВ}$
Теперь переведем в джоули:
$E_4 = 1 \cdot 10^{12} \cdot 1.6 \cdot 10^{-19} \text{ Дж} = 1.6 \cdot 10^{(12-19)} \text{ Дж} = 1.6 \cdot 10^{-7} \text{ Дж}$
Ответ: $1.6 \cdot 10^{-7} \text{ Дж}$.
14 ТэВ
Переведем тераэлектрон-вольты в электрон-вольты:
$E_5 = 14 \text{ ТэВ} = 14 \cdot 10^{12} \text{ эВ}$
Теперь переведем в джоули:
$E_5 = 14 \cdot 10^{12} \cdot 1.6 \cdot 10^{-19} \text{ Дж} = (14 \cdot 1.6) \cdot (10^{12} \cdot 10^{-19}) \text{ Дж} = 22.4 \cdot 10^{-7} \text{ Дж} = 2.24 \cdot 10^{-6} \text{ Дж}$
Ответ: $2.24 \cdot 10^{-6} \text{ Дж}$.
