Question

Самолет с размахом крыльев 18 м движется горизонтально со скорость 800 км/ ч . Вертикальная составляющая напряженности магнитного поля Земли Н=40 А*м. Определить разность потенциалов между концами крыльев.

Answer 1

Дано:
L=18 м
V=800 км/ч     ИЛИ  V ≈ 220 м/с
H=40 А*м
____________
U - ?

Разность потенциалов на концах проводника:
U = B*V*L

Но:
B=μ₀*H

Тогда:
U = μ₀*H*V*L = 4*π*10⁻⁷*40*220*18 ≈ 0,20 В

Ответ: U=0,20 вольт

Answer 2

Calculation of Potential Difference between the Ends of the Wings

To calculate the potential difference between the ends of the wings of an airplane, we need to consider the velocity of the airplane, the wingspan, and the vertical component of the Earth's magnetic field.

Given: - Wingspan of the airplane: 18 m - Horizontal velocity of the airplane: 800 km/h (which can be converted to m/s)

To calculate the potential difference, we need to use the formula:

Potential Difference (V) = Magnetic Field Strength (B) x Velocity (v) x Wingspan (L)

However, we are only given the vertical component of the Earth's magnetic field, not the total magnetic field strength. Without the total magnetic field strength, we cannot accurately calculate the potential difference between the ends of the wings.

Unfortunately, the provided search results do not contain the necessary information to determine the total magnetic field strength or provide a direct answer to the question. Therefore, we cannot provide a specific value for the potential difference between the ends of the wings based on the given information.
