Question

Q=0,4 Oм.мм:2А=15кг ДжG=300 КлI=20AS=0,004cm^2=?q-?

Answer 1

Ответ:

Объяснение:

р =0,4 Oм*мм^2 / м

А=15000Дж

q =300 Кл

I=20A

S=0,004cм^2= 0.4 мм^2

L-?

A = R*t*I^2

I = q / t   => t = q / I

A = R*q*I^2 / I = R*q*I

R = A / (q*I)

R = p*L /S

p*L /S = A / (q*I)

L = S*A / (p*q*I) = 0.4*15000 / (0.4*300*20) = 2.5 м

Answer 2

It seems like you've provided a set of symbols and values without a clear question. I'll do my best to interpret and address what you've provided:

1. Q = 0.4 Ohm * mm
2. 2A = 15 kg * J (kilograms times Joules)
3. G = 300 Coulombs (C)
4. I = 20 Amperes (A)
5. S = 0.004 cm^2

It appears you're looking for a value or calculation for "q-?"

However, I'm not sure what "q" represents in your context. It's not defined in your provided symbols. If you can clarify the meaning or context of "q," I'd be happy to assist you with a calculation or explanation related to your question.
