Answer:
A. True
Explanation:
This is because these aircraft experiences different types of vibrations which include buffet vibrations and aerodynamic flutter. Buffet vibrations are vibrations caused by an interruption of airflow. Buffet vibrations are usually felt when the aerodynamic brakes are applied.
Aeroelastic flutter is the most dangerous type of vibration. This occurs when energy added to the wings due to airflow is greater than that lost due to damping. Aeroelastic flutter can cause aircraft to fail when the vibrations are large enough.
Answer:
The time is 0.563 ns.
Explanation:
Given that,
Index of refraction of glass = 1.41
Distance = 12.0 cm
Angle = 33.0°
We need to calculate the refraction angle
Using Snell's law

put the value into the formula



We need to calculate the velocity of beam in glass
Using formula of velocity

Put the value into the formula


We need to calculate the time
Using formula of distance





Hence, The time is 0.563 ns.
Answer:
3100 m/s
Explanation:
The relationship between frequency and wavelength of a wave is given by the wave equation:

where
v is the speed of the wave
f is its frequency
is the wavelength
For the wave in this problem,
f = 15,500 Hz

Therefore, the wave speed is

C.) chemical to electrical to light
