The formula for average speed is S=D/T

1. S=72m/37s

Divide

S= 1.94

Kira's average speed is 1.94m/s.

2. S=7.5km / 1.5h

S=5

Your average speed is 5km/h

3. S=1260km/3.5h

S=360

The airplanes average speed is 360km/h

The windchill index tells you

marshall27 [118]

<span>The windchill index tells you A. how wind and temperature affect your body in winter. This is how you perceive the temperature outside due to the flow of air. The windchill index is always lower than the measured temperature outside. This is because wind increases the rate at which your body loses heat. For example, if it is 25 degrees outside, but there is a strong wind, the perceived temperature on your skin may be closer to 15 degrees.</span>

Razona si, en las experiencias de Faraday, el efecto producido moviendo el circuito será el mismo que el producido moviendo el i

const2013 [10]

Answer:

moving the circuit or the magnet gives the same result

Explanation:

The faraday effect establishes that the temporal variation of imaginative flow produces an electric potential

fem = $\frac{d \phi }{dt}$ dfi / dt

the magnetic flux is

Ф = B. A = B A cos θ

suppose for simplicity that the angle is zero so cos 0 = 1

Φ = B A

By analyzing this expression, the change in magnetic flux can converge while keeping the magnetic field fixed and varying the electric field or keeping the electric field fixed and varying the magnetic field.

Consequently moving the circuit or the magnet gives the same result
