Question

L2=5см F1=15H F2=30Н L1=?

Answer 1

Тут же всё по формуле
F1l1 = F2l2
надо умножить F1 на L1 и разделить на L2
т. е. 30Н * 20 см и / 10
Ответ: 60 Н

Answer 2

To determine the value of L1, we can use the formula for inductance in a series circuit:

L1/L2 = F1/F2

Plugging in the given values:

L1/5cm = 15H/30N

To solve for L1, we can cross-multiply:

L1 * 30N = 5cm * 15H

L1 * 30N = 75H cm

Since the units don't match, we need to convert cm to H:

1H = 100cm, so 75H cm = 75H * 100cm/H = 7500cm

Now, we can solve for L1:

L1 * 30N = 7500cm

Dividing both sides by 30N:

L1 = 7500cm / 30N

Simplifying:

L1 = 250cm

Therefore, L1 is equal to 250cm.
