ПОМОГИТЕ РЕШИТЬ ЗАДАЧУ ПОЖАЛУЙСТА!!! I(сила тока)=21А L(длина)=0,4М В(напряжение)=1,2 тесла sin 90= 1 L=0,25 м найти работу(А)?

Answer 1

I=21 A    L=0.4 м   B=1.2 Тл    s=0.25 м   α=90   A=?

A=F*s*sinα=I*B*L*s*sin90=21*1.2*0.4*0.25*1=2.52 Дж

Answer 2

Calculation of Work (А) in the Given Problem

To calculate the work (А) in the given problem, we need to use the formula:

Work (А) = Current (I) × Length (L) × Magnetic Field (B) × sin(θ)

Given values: - Current (I) = 21 A - Length (L) = 0.4 m - Magnetic Field (B) = 1.2 Tesla - Angle (θ) = 90 degrees (sin(90) = 1)

Substituting these values into the formula, we get:

Work (А) = 21 A × 0.4 m × 1.2 Tesla × 1

Simplifying the equation, we find:

Work (А) = 10.08 Joules

Therefore, the work (А) in the given problem is 10.08 Joules.
