Question

1. F=200kH, s=10cm. A-? 2. F=180mH, s=2mm, t=15cm. N-?

Answer 1

Ответ:

200-180=20

10+2=12

12+15=27

20+27=47

Answer 2

1. To find the value of A, given that F = 200 kH and s = 10 cm, we need to use the equation A = F/s. Substituting the given values, we have:

A = 200 kH / 10 cm

To simplify the calculation, we need to convert the units. We can convert kH to H by multiplying by 1000, and we can convert cm to meters by dividing by 100. This gives us:

A = (200 * 1000 H) / (10 / 100 m)

Simplifying further:

A = 2,000,000 H / 0.1 m

A = 20,000,000 H/m

Therefore, the value of A is 20,000,000 H/m.

2. To find the value of N, given that F = 180 mH, s = 2 mm, and t = 15 cm, we need to use the equation N = F * s / t. Substituting the given values, we have:

N = 180 mH * 2 mm / 15 cm

Again, we need to convert the units to ensure they are consistent. We can convert mH to H by dividing by 1000, mm to meters by dividing by 1000, and cm to meters by dividing by 100. This gives us:

N = (180 / 1000 H) * (2 / 1000 m) / (15 / 100 m)

Simplifying further:

N = 0.00018 H * 0.002 m / 0.15 m

N = 0.00000036 H * 0.002 m / 0.15 m

N = 0.00000000072 H * 0.002 m / 0.15 m

N = 0.00000000144 H * m / 0.15 m

N = 0.00000000144 H

Therefore, the value of N is 0.00000000144 H.
