Question

Срочно!!! Помогите!!! Кто знает физику, помогите решить задачу!!! Вы сами решаете сколько баллов я вам должен!! Просто у нас самостоятельная работа до окончания урока осталось 14 минут. 3.Напряжение на концах проводника 16 В. Какова сила тока в проводнике, если за 1 минуту совершена работа 0,5 кДж?

Answer 1

Ответ:

0,52 А

Объяснение:

Силу тока можно найти по формуле I = q / t

A = qU; q = A / U = 0,5 кДж / 16 В = 500 Дж / 16 В = 31,25 Кл

I = 31,25 Кл / 60 с ≅ 0,52 А

Answer 2

Problem Statement

The problem states that the voltage across a conductor is 16 V, and the work done in 1 minute is 0.5 kJ. We need to find the current flowing through the conductor.

Solution

To find the current flowing through the conductor, we can use the formula:

Power (P) = Work (W) / Time (t)

The power can also be calculated using the formula:

Power (P) = Voltage (V) * Current (I)

By equating the two formulas, we can find the current flowing through the conductor.

Let's solve the problem step by step:

Step 1: Convert the work done from kilojoules (kJ) to joules (J). - 1 kJ = 1000 J - Therefore, 0.5 kJ = 0.5 * 1000 J = 500 J

Step 2: Substitute the given values into the formula: - Power (P) = Work (W) / Time (t) - Power (P) = 500 J / 60 s (since 1 minute = 60 seconds)

Step 3: Calculate the power: - Power (P) = 500 J / 60 s = 8.33 W (rounded to two decimal places)

Step 4: Substitute the power and voltage values into the formula: - Power (P) = Voltage (V) * Current (I) - 8.33 W = 16 V * Current (I)

Step 5: Solve for the current (I): - Current (I) = Power (P) / Voltage (V) - Current (I) = 8.33 W / 16 V

Let's calculate the current:

Current (I) = 0.5206 A (rounded to four decimal places)

Therefore, the current flowing through the conductor is approximately 0.5206 A.

Please note that the calculations are rounded to the appropriate number of decimal places for clarity.
