Question

Help me please!!! 9×10^-3 Вб-2×10^-3Вб/5×10^-3= Это физика

Answer 1

А скобки не забыл?

(9·10⁻³ - 2·10⁻³) / (5·10⁻³) = 7·10⁻³ / (5·10⁻³) = 7 / 5 = 1,4

Answer 2

Of course, I'd be happy to help you with this physics problem!

Let's simplify the expression step by step:

1. 9×10^-3 Вб - 2×10^-3 Вб = (9 - 2) × 10^-3 Вб = 7 × 10^-3 Вб

2. Now we have: 7 × 10^-3 Вб / 5 × 10^-3

When dividing two quantities with the same base (in this case, 10), you subtract the exponents:

3. 7 × 10^-3 Вб / 5 × 10^-3 = (7 / 5) × 10^(-3 - (-3)) Вб = (7 / 5) × 10^0 Вб

Since any number multiplied by 10^0 is just the number itself (10^0 = 1), the expression simplifies to:

4. (7 / 5) × 10^0 Вб = 7 / 5 Вб

So, the result of the expression is 7/5 Вб or 1.4 Вб.

Keep in mind that Вб stands for "weber," which is the unit of magnetic flux. If you have any more physics questions or need further assistance, feel free to ask!
