∴
Answer: Did you ever find the answer I’m on the same question
Explanation:
Answer:
B = 2.93 x 10⁻⁵ T
Explanation:
The magnetic field due to a straight long wire carrying a current can be found by using Biot-Savart Law, as follows:
B = μ₀I/2πr
where,
B = Magnitude of the magnetic Field = ?
μ₀ = Permeability of free space = 4π x 10⁻⁷ Tm/A
r = distance from wire = 0.03 m
I = Current = 4.4 A
Therefore,
B = (4π x 10⁻⁷ Tm/A)(4.4 A)/(2π)(0.03 m)
<u>B = 2.93 x 10⁻⁵ T</u>
N = 1 - (QC/QH)
n = efficiency
QC = Cold Reservoir = 220 K
QH = Hot Reservoir = 680 K
Answer: The engine's efficiency is 67.6% .
