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.
The most common one is junk food and sugary snacks are very very addicting! they are almost like drugs!!!
Gravitational force between sun and planet is given by,
Thus, The force of gravitation is inversely proportional to the distance.
Kepler's law states that the square of period of planet is proportional to cube of semi major axis of its orbit.
The time period of planet is more when the gravitational force is less.
Thus, planet Y is closer to earth because sun exert greater gravitational force than planet Z.
Answer:
the molrcular mass of carbon dioxide id 44.01amu
Explanation:
plz make me brainliest
the speed would have to be somewhere between 1.667 or 1.666 miles per minute.
add 30, 15, 5 together and you will get 50
50 is the total miles traveled
then you multiply 30 by 1.666 and you will get 49.98 but it's still not quite 50 miles
if you multiply 30 by 1.667 and you will get 50.01 but its a little over to miles
i got the 30 from the minutes traveled
anyway that's the best i got for speed
