Since the discrete Fourier series, the Sampling rate, would be the equivalent of the inverse of the passage of time, that is, to the frequency, mathematically this can be written as,
In turn, the time can be described depending on the period and the amount of data samples taken. This would be,
Here,
m = Data Samples
T = Period
Replacing,
Replacing the value of the time from the first equation,
At the same time, the range then will be given between the basic frequency to the half of the sample, that is,
Therefore the lowest frequency is 5000Hz and highest 9.165Hz
The answer is shorter the wavelength, higher the frequency and higher the energy.
<u>Explanation:</u>
The sun radiates UV energy in a wide range of wavelength, which are invisible to human eyes. The shorter the wavelength, the more energetic the radiation, and the greater the potential for harm.
The relationship between wavelength and wave energy is shorter the wavelength, higher the frequency and higher the energy.
It has a frequency ranges from 8 × 10^14 to 3 × 10^16 cycles per second, or hertz (Hz), and wavelengths id about 380 nanometers to about 10 nm.
Answer:
a) a right triangle, b) x = 0.167 m
Explanation:
a) It is asked to find which geometry figure describes the movement of the ant.
Let's use trigonometry with the angles measured in radians
tan θ = y / x
tan θ = 6/10
θ = tan⁻¹ 0.6
θ = 0.54 rad
this value is equal to the upward slope therefore the geometric body that describes the movement is a right triangle
b) it is asked to find the horizontal displacement for a vertical displacement of y = 0.1 cm x = y / tan tea
x = 0.1 / tan 0.54
x = 0.1668 m
x = 0.167 m
Explanation:
The postulate of Special Relativity was not violated because it was the dimensions of space which were expanding. The postulate applies to objects moving through space.
The postulates of special relativity are
1. Laws are physics are same all objects in inertial frame of reference and
2. Speed of light is a constant( in vacuum) for all observers, regardless of the motion of source or the observer.
