The pipe that produces the highest-frequency sound is the 5 cm long pipe.
According to the Fundamental Principle, the length of the tube of the pipe and its frequency is inversely proportional.
This means that the longer the tube, the lower the frequency and vice versa. Therefore, between the 25cm long pipe and the 5cm long pipe, the shorter pipe produces the highest-frequency sound.
Answer:
all the lamps has the same brightness
Answer:
7] Force = mass × acceleration
Force = 2 × 5
<u>Force = 10 N</u>
<u></u>
8] Velocity = acceleration due to gravity × time taken
Velocity = 9.8 × 12
<u>Velocity = 117.6 m/s</u>
Answer:
When flying the LNAV Approach, the missed approach point (MAP) would be indicated by reaching:
C. the RW30 waypoint.
Explanation:
- In Aviation, LNAV stands for Lateral Navigation. The option a is incorrect as an altitude of 3100 feet refers to the decision altitude not the missed approach point.
- The option b is incorrect as a distance of 1.5 NM to RW30 referring to the Visual descent point (VDP) is 1.5 nautical miles for the Runway (RW) 30 from threshold.
- The option c is correct as Missed approach point is designed to coincide with the runway threshold. The RW 30 way point is referring to the way point to the threshold for the Runway 30.
Answer:
Explanation:
Average acceleration
is the variation of velocity
over a specified period of time
:
Where:
being
the initial velocity and
the final velocity (according to the information given from the described graph)

Then:
