Question

R1=30м R2=70м U=15B t=3мин Q=?

Answer 1

Q=I^2*R*t
Если последовательное соединение - тогда Rобщее=3+7=10 Ом
t=3мин=180с
I=U/R=15/10=1.5А
Q=1.5^2*10*180=2.25*10*180=4050Дж

Answer 2

To calculate Q, we can use the formula:

Q = (U * t) / (2 * π * (R1 + R2))

Given: R1 = 30 m R2 = 70 m U = 15 B t = 3 min

Converting minutes to seconds: t = 3 min * 60 sec/min = 180 sec

Substituting the values into the formula:

Q = (15 B * 180 sec) / (2 * π * (30 m + 70 m))

Q = (15,000,000,000 * 180) / (2 * 3.14159 * 100)

Q ≈ 85,486,173.61

Therefore, Q is approximately 85,486,173.61.
