Explanation:
Solution
(1) Part (a)a waveform has a high frequency components compared to another waveform. the corresponding frequency components should be high.
So for the wave form a the corresponding frequency spectrum is (3)
(2) For part (b), waveform has three harmonics, the corresponding frequency spectrum is (1)
(3) The time domain waveform plot (c) is a sine wave but there exists a dc component.
Thus x[0] ≠0
For (c) the corresponding frequency spectrum is (5)
(4) For part (d) the corresponding frequency spectrum is (2)
(5) A sine wave is made of a single frequency only and its spectrum is a single point
For (e) the corresponding frequency spectrum is (4)
Answer:
The branches of physics are;
- Classical physics
- Modern physics
- Nuclear physics
- Atomic physics
- Geophysics
- Biophysics
Explanation:
Physics is a branch of science that studies nature, properties of matter and energy. The subjects in study are; mechanics, light, heat, light, sound, electricity, properties of atoms and magnetism.
The common branches are;
- Thermodynamics which that studies heat, how it is transferred and effects
- Sound that studies production, properties and application of sound waves
- Light that deals with properties,pysical aspects and objects that utilize light
- Electricity and magnetism that studies charges, their effects and relation with magnetism
- Classical physics that studies laws of motion and gravity
- Modern physics that study theory of relativity and quantum mechanics
Answer:
7 available
Explanation:
Since 3 colors are available r = 3
Total combination = 35
nCr = 35 ---1
nCr = n!/(n-r)!r!---2
We put equation 1 and 2 together
n-1)(n-2)(n-3)!/n-3)! = 35x 3!
We cancel out (n-3)!
(n-1)(n-2) = 210
7x6x5 = 210
nC3 = 35
7C3 = 35
So If there are 35 combinations, 7 colors are available.
Thank you!
