The ratio of the primary turns to the secondary turns is 1/3
The correct answer to the question is Option A. 1/3
From the question given above, the following data were obtained:
- Primary turn (Nₚ) = 225 turns
- Secondary turn (Nᵣ) = 675 turns
- Ratio of primary to secondary =?
Ratio = Nₚ/Nᵣ
Nₚ/Nᵣ = 225 / 675
Nₚ/Nᵣ = 1/3
Therefore, the ratio of the primary turns to the secondary turns is 1/3

Answer: 35.3m (3sigfig)
Explanation:
I would use the equation wave speed= frequency x wavelength
Rearrange to get wavelength=wave speed/ frequency
Plug in your numbers and that's the answer you get
Hope this helps :)
Answer:
E = 15.7 KJ/mol
Explanation:
The number of vacancies in a metal is given by
n = n₀ 
They tell us that
n = 5 no
We replace
5 n₀ = n₀ e^{-E/KT}
-E / KT = ln 5
E = KT ln 5
E = 1,381 10⁻²³ 1170 ln 5
E = 2.6 10⁻²⁰ J
To take (J / mol) we multiply between Avogadro's number
E = 2.6 10⁻²⁰ 6.022 10²³
E = 1.57 10⁴ J / mol
E = 15.7 KJ/mol
