Question

Самолёт летит горизонтально со скоростью 1200 км/ч. Найдите разность потанциалов,возникающую на концах крыльев, если вертикальная состовляющая индукции магнитного поля Земли равна 5*10Тл. Размах крыльев равен 40м

Answer 1

Считаю, что магнитная составляющая B=5*10^-5 Тл( проверьте)
U=B*V*L=5*10^-5*333,3*40=0,67 В

Answer 2

Calculation of Potential Difference on the Wings of an Airplane

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

Given: - Horizontal velocity of the airplane: 1200 km/h - Vertical component of the Earth's magnetic field: 5 * 10^(-5) T - Wingspan of the airplane: 40 m

To calculate the potential difference, we can use the formula:

V = B * L * Vh

Where: - V is the potential difference - B is the vertical component of the Earth's magnetic field - L is the wingspan of the airplane - Vh is the horizontal velocity of the airplane

Let's substitute the given values into the formula:

V = (5 * 10^(-5) T) * (40 m) * (1200 km/h)

Before we proceed with the calculation, let's convert the horizontal velocity from km/h to m/s:

1200 km/h = (1200 * 1000 m) / (3600 s) ≈ 333.33 m/s

Now, we can calculate the potential difference:

V ≈ (5 * 10^(-5) T) * (40 m) * (333.33 m/s)

Calculating this expression gives us:

V ≈ 0.6667 V

Therefore, the potential difference that arises on the ends of the wings of the airplane is approximately 0.6667 V.

Please note that the units for potential difference are volts (V).
