Answer:
If a pitch vibrates at 880 cycles, the octave below would vibrate at 440 cycles.
Explanation:
Pitch of sound is defined as relative highest and the lowest point of sound. The pitch is dependent on frequency of vibration.
Octave is defined as a tone which is formed due to merging of two different tone. The resultant tone is merged so well that it sound like a single tone.
Thus, Number cycle in octave =
Number cycle in octave =
Number cycle in octave = 440
Thus, If a pitch vibrates at 880 cycles, the octave below would vibrate at 440 cycles.
Answer:
I think the correct answer is B.
Answer:
Φ = 2.26 10⁶ N m² / C
Explanation:
The electric flow is
Ф = E .ds = / ε₀
Since we have two components for this flow. The uniform electric field and the flux created by the point charge.
The flux of the uniform electric field is zero since the flux entering is equal to the flux leaving the Gaussian surface
The flow created by the point load at the origin is
Φ = q_{int} /ε₀
Let's calculate
Φ = 2.00 10⁻⁶ /8.85 10¹²
Φ = 2.26 10⁶ N m² / C
