Answer: To complete the process of digestion after the food is ingested by mouth.
Explanation:
The food that we eat is ingested by mouth and here the mechanical degradation of food takes place. This breaks down the food into smaller pieces.
Mouth also contains the enzyme that is responsible for the digestion of starch.
Then the food from the mouth reaches the stomach where various types of digestive juices and enzymes are secreted to digested the food.
Hence, mouth and stomach must be near in the digestive system.

Answer: 1433.3 m/min
Explanation:
For 86 Km/h converted to a (m/min), convert kilometers to meters, and hour to minutes
So, 86 Km/h means 86 kilometers per 1 hour
- If 1 kilometer = 1000 metres
86 kilometers = 86 x 1000 = 86,000m
- If 1 hour = 60 minute
1 hour = 60 minutes
In m/min: (86,000m / 60 minute)
= 1433.3 m/min
Thus, 86 Km/h convert to 1433.3 m/min

Answer:
The frequency of sound wave created by trumpet is 437.5Hz
Explanation:
Given
the speed of sound wave = 350 m
the wavelength of sound wave = 0.8 m
the frequency of sound wave = ?
All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:
v = fλ, where
v is speed of the wave
f is frequency of the wave
λ is wavelength of the wave
therefore frequency of sound wave is given by
f = v/λ
= 350m/0.8m
= 437.5
= 437.5Hz (since 1 = 1 Hz (Hertz)
Hence the frequency of sound wave created by trumpet is 437.5Hz
