Answer:
The resulting speed of the airplane is 150 Km/h
Explanation:
The airspeed of the plane is 120 Km/h due North. The wind came from West pointing to the East at 90 Km/h
Both speeds are acting in different directions, so they must be added as vectors. Both vectors and the resulting velocity (Vr) are shown in the image below
The magnitude of that velocity can be computed by using Pythagoras's theorem:
The resulting speed of the airplane is 150 Km/h
Answer:
The width is
Explanation:
From the question we are told that
The wavelength is
The width of the slit is
The distance of the screen is
Generally the central maximum is mathematically represented as
Here y is the width of the first order maxima which is mathematically represented as
substituting values
So
