Answer:
If the thrust is increased, the aircraft accelerates and the velocity increases. This is the second part sited in Newton's first law; a net external force changes the velocity of the object. The drag of the aircraft depends on the square of the velocity. So the drag increases with increased velocity.
Answer: 17.59 Hz and 4.87 m
Explanation:
The fundamental frequency of the sound from an open-open pipe is given as
f= 
where v= 343 m/s
L= 32 feet= 
= 9.75 m
So,
f= 
= 17.59 Hz
The length of open-closed tube is related to frequency by formula
f= 
or L=
L= 
L= 4.87 m
Answer:
No
Explanation:
The work that can be turned into heat equals 100% and there is no thermodynamic law that says that cannot be.
Answer: in a medium
Explanation:
Mechanical waves require medium to transfer energy. The medium particles vibrate about their fixed position to transfer energy. There is no transport of medium particles.
Example, sound waves are mechanical waves. The sound travels through compression and rarefaction of the medium particles.
The frequency stays the same and the wavelength increases.
Explanation;
Sound waves are a type of mechanical wave which requires a material medium for transmission. The transmission of such waves occurs as a result of vibration of particles in the material medium. The faster the vibration of the particles the higher the speed of the sound waves.
When a sound enters a new medium where the sound travels faster, it means the vibration of particles is high, and the wavelength of the waves increases which means the speed of the wave has increased. The frequency on the other hand will remain constant.
