Answer:
this sound wave get to the other by either undergoing either reflection,absorption or transmission
Explanation:
When a sound wave meets an obstacle, some of the sound is reflected back from the front surface and some of the sound passes into the obstacle material, where it is absorbed or transmitted through the material like the building walls
Thus, Reflection and absorption are dependent on the wavelength of the sound. Hence percentage of the sound transmitted through an obstacle depends on how much sound is reflected and how much is absorbed.
Measuring the heat of chemical reactions or physical changes.
Answer:
-9.44444
Formula: (15°F-32) ×5/9= -9.44444
Hope this helped :)
Explanation:
The height of an object thrown upward from the floor of a canyon 106 ft deep, with an initial velocity of 120 ft per second. The equation is given by :
Since, the depth of the canyon is (-106 feet) and the time taken by the object to rise to the height of the canyon wall is calculated as :
h = 0
On solving the above quadratic equation,
x₁ = 1.023 seconds
and
x₂ = 6.477 seconds
So, the time taken by the object to rise to the height of the canyon wall is 1.023 seconds (ignoring 6.477 seconds). Hence, this is the required solution.
Answer:
b. wavelength
Explanation:
The following quantities are used to describe a wave:
- Frequency --> it is the number of complete cycles/oscillations of the wave per second. Generally represented with or f.
- Wavelength --> it corresponds to the distance between two successive crests (or between two successive troughs) of a wave. Generally represented with
- Quantum number --> for a wave, the following quantity
is called quantum number of the wave
- Velocity --> the velocity of a wave is given by the product between wavelength and frequency:
Therefore, the correct answer is b. wavelength.
