№10 (с. 105)
Условие. №10 (с. 105)
скриншот условия
10. Заполните в тетради пустые графы таблицы 13. Последнюю строчку придумайте сами.
Таблица 13
$\text{q}$, Кл $\text{t}$, с $\text{I}$, А
50 5
600 0,2
30 0,5
Решение. №10 (с. 105)
Для заполнения пустых граф таблицы используем формулу, связывающую силу тока $\text{I}$, электрический заряд $\text{q}$ и время прохождения заряда $\text{t}$:
$I = \frac{q}{t}$
Из этой формулы можно выразить заряд и время:
$q = I \cdot t$
$t = \frac{q}{I}$
Рассчитаем недостающие значения для каждой строки.
Первая строка
Дано:
$q = 50 \text{ Кл}$
$t = 5 \text{ с}$
Найти:
$\text{I}$
Решение:
Для нахождения силы тока воспользуемся основной формулой:
$I = \frac{q}{t} = \frac{50 \text{ Кл}}{5 \text{ с}} = 10 \text{ А}$
Ответ: 10 А.
Вторая строка
Дано:
$q = 600 \text{ Кл}$
$I = 0{,}2 \text{ А}$
Найти:
$\text{t}$
Решение:
Для нахождения времени выразим его из основной формулы:
$t = \frac{q}{I} = \frac{600 \text{ Кл}}{0{,}2 \text{ А}} = 3000 \text{ с}$
Ответ: 3000 с.
Третья строка
Дано:
$t = 30 \text{ с}$
$I = 0{,}5 \text{ А}$
Найти:
$\text{q}$
Решение:
Для нахождения заряда выразим его из основной формулы:
$q = I \cdot t = 0{,}5 \text{ А} \cdot 30 \text{ с} = 15 \text{ Кл}$
Ответ: 15 Кл.
Четвертая строка (придуманная)
Согласно заданию, придумаем последнюю строчку самостоятельно. Например, пусть через проводник за 2 минуты ($120$ секунд) прошел заряд в $\text{60}$ Кл. Найдем силу тока.
Дано:
$q = 60 \text{ Кл}$
$t = 120 \text{ с}$
Найти:
$\text{I}$
Решение:
Используем формулу для силы тока:
$I = \frac{q}{t} = \frac{60 \text{ Кл}}{120 \text{ с}} = 0{,}5 \text{ А}$
Ответ: 0,5 А.
Итоговая заполненная таблица:
| q, Кл | t, с | I, А |
|---|---|---|
| 50 | 5 | 10 |
| 600 | 3000 | 0,2 |
| 15 | 30 | 0,5 |
| 60 | 120 | 0,5 |
