Question

Помогите, пожалуйста, очень срочно! Самолет летит со скоростью 1800 км/ч, модуль вертикальной составляющей вектора индукции магнитного поля Земли 4 • 10^-5 Тл. Какова ЭДС индукции между концами крыльев самолета, если размах крыльев равен 25 м?​

Answer 1

Ответ:

Всё в решении

Объяснение:

1800 км/ч = 500 м/с

500*25*(4*10^-5) = 0,5 В

Answer 2

Calculation of Induced EMF

To calculate the induced electromotive force (EMF) between the ends of the airplane wings, we need to use Faraday's law of electromagnetic induction. According to Faraday's law, the induced EMF is equal to the rate of change of magnetic flux through a closed loop.

The formula to calculate the induced EMF is:

EMF = -N * dΦ/dt

Where: - EMF is the induced electromotive force (in volts) - N is the number of turns in the loop - dΦ/dt is the rate of change of magnetic flux (in webers per second)

In this case, the airplane wings can be considered as a loop, and the magnetic flux through the loop is given by the product of the magnetic field strength and the area of the loop.

The formula to calculate the magnetic flux is:

Φ = B * A

Where: - Φ is the magnetic flux (in webers) - B is the magnetic field strength (in teslas) - A is the area of the loop (in square meters)

Let's calculate the induced EMF step by step.

1. Calculate the magnetic flux: - Given: B = 4 * 10^-5 T (magnetic field strength) - Given: A = 25 m^2 (area of the airplane wings) - Φ = B * A

2. Calculate the induced EMF: - Given: N = 1 (assuming one loop) - Given: dΦ/dt = 0 (assuming a constant magnetic field) - EMF = -N * dΦ/dt

Let's perform the calculations.
