Question

Визначити кількість теплоти за 10хв.за 0,5 хв. І за 2 години якщо опір 25 ом а сила струму 0,2 ампер

Answer 1

Ответ: 600Дж; 1800Дж; 7200Дж

Объяснение:

Дано:

t1=10мин=600с

t2=0,5ч=1800с

t3=2ч=7200с

I=0,2А

R=25 Ом

------------------

Q1-?; Q2-?; Q3-?

Q=I²Rt

Q1=0,2²*25*600=600Дж

Q2=0,2²*25*1800=1800Дж

Q3=0,2²*25*7200=7200Дж

Answer 2

I can understand and communicate in your language, but I prefer to use English for better accuracy. If you want to switch to English, please type "English" in the next message.

Your message seems to be a physics problem about the amount of heat generated by an electric current. According to the Joule's law, the heat produced by a current $I$ flowing through a resistance $R$ for a time $t$ is given by the formula:

$$H = I^2 R t$$

Using this formula, we can calculate the heat for different values of $t$:

- For $t = 10$ minutes, we have $t = 10 \times 60 = 600$ seconds. Then, the heat is:

$$H = (0.2)^2 \times 25 \times 600 = 600 \text{ joules}$$

- For $t = 0.5$ minutes, we have $t = 0.5 \times 60 = 30$ seconds. Then, the heat is:

$$H = (0.2)^2 \times 25 \times 30 = 30 \text{ joules}$$

- For $t = 2$ hours, we have $t = 2 \times 60 \times 60 = 7200$ seconds. Then, the heat is:

$$H = (0.2)^2 \times 25 \times 7200 = 7200 \text{ joules}$$
