A sound-producing object is moving toward an observer. The sound the observer hears will have a frequency higher than that actually being produced by the object.
Answer:
Presiune = 350 N/m²
Explanation:
Având în vedere următoarele date;
Forța = 700 N
Suprafață = 2 m²
Pentru a găsi presiunea;
Matematic, presiunea este dată de formulă;
Presiune = forță/zonă
Înlocuind în formulă, avem;
Presiune = 700/2
Presiune = 350 N/m²
Answer:
Q
Explanation:
To know which symbol defines the wavelength, we must know the definition of wavelength.
Wavelength can be defined as the distance between two successive crests (i.e the highest part) or troughs (the lowest part) of a wave.
Considering the diagram given above, Q shows the distance between two successive crests (i.e the highest part) of the wave. Therefore, Q is the wavelength of the wave given in the diagram above.
Crust
Explanation:
The crust is the layer of the earth with the least dense materials. The crust is made up of silicate materials.
- During the early stage in the formation of earth.
- The earth differentiated minerals based on their densities.
- Lighter minerals stayed afloat while the denser ones sank to the core of the earth.
- The core is made up of the most dense metallic minerals.
- As we go deep into the earth density increases.
- Density of crust ranges from 2.-3.3g/cm³
- The core is about 13.8g/cm³ dense.
