Answer:
Technician A and B are correct
Explanation:
Technician A is correct because the system app is used to calculate the amount of fuel required to go with the airflow.
Technician B is correct because Maf is incorporated with a sensor for detecting the amount of airflow.
Answer:
Explanation: The part of the wave he is traveling on is the crest
Answer:
we are on the same frame of reference moving with the earth with the same velocity.
Explanation:
- Given that the earth is continuously moving at a speed of about 30 kilometers per second in the space. This means this is the observed speed from and external frame of reference in space being at rest.
- But when we jump from vertically on the earth we are already on the same moving frame of reference and bounded to it by the gravity and hence when we jump off its surface we jump with its velocity of motion and so does every other object present on the earth and hence we do not collide with the wall when taking a vertical jump beside it. To us the wall seems to be at rest because we both are on the same frame of the reference.
Answer:
Refraction only occurs when the light is incident to the surface at some positive angle. When light is perpendicular to a surface there is no bend to the ray.
Using Snell's law, the math looks like this
n₁sinθ₁ = n₂sinθ₂
at an incidence of 0°
n₁sin(0) = n₂sinθ₂
0 = n₂sinθ₂
as n₂ is always a positive number, sinθ₂ must equal 0 meaning θ₂ = 0
So while there will be refraction of light a position O, which is the exact center of the semicircular prism and the refracted ray will follow a radial line, there will be no refraction of light at P because the light is traveling perpendicular to the surface there. There will be a change in light velocity because of the change in the medium, but no refraction.

Answer:
2.67×10² m
Explanation:
Applying
V = λf............... Equation 1
Where V = Velocity of radio wave, λ = wave length, f = frequency.
make λ the subject of the equation
λ = V/f................ Equation 2
From the question,
Given: V = 2.99×10⁸ m/s, f = 1.12×10⁶ Hz.
Substitute these values into equation 2
λ = (2.99×10⁸)/(1.12×10⁶)
λ = 2.66696×10² m
λ ≈ 2.67×10² m
