10,000 meters: 1,000 meters in every kilometer.
Answer:
66 rpm
Explanation:
The period of oscillation is given by
where T is time period of oscillation which is given as 0.35 s, k s spring constant and m is the mass of the object attached to the spring.
Also, net force is given by
Net force=
where is the elongation, L is original length, is the angular velocity
Substituting the equation of into the above we obtain
Answer:
the answer to your question is b
Answer:
The wavelength is
The wave number is
The wave function is
Explanation:
From the question we are told that
The frequency of the sound wave is
The speed of the wave is
The wavelength of the wave is mathematically evaluated as
substituting values
The wave number is mathematically represented as
substituting values
The general form of wave function is
given that the amplitude is
While which is the angular velocity is represented as
and k which is the angular wave number is mathematically represented as
The wave function becomes
substituting values
C. diffraction
Diffraction by description is occurrence
where the sound wave is interrupted or interacts with certain obstructions or
barriers. According to Huygens-Fresnel principle, it is where the waves are interfered
by said circumstances during its travel in the confined specific space.
Furthermore, the amount of
size the wavelength is directly proportional to its interacted slit or barrier
thus, these behaviors and amount are positively correlated.
Moreover, it occurs in a variety
of waves –may it be sound waves, water waves or electromagnetic waves.
