Answer:

I = 9.82 10⁻⁷ W / m²

Explanation:

The intensity of the sound wave is the energy of the wave between the order per unit area of ​​the same

      I = P / A = E / T A

the energy is calculated by integrating the mechanical energy in a period, where the mass is changed by the density and ‘s’ is the amplitude of the sound wave

     I = ½ ρ v (w s)²

   

     I = ½ 1.35 328 (2π 530 2.00 10⁻⁸)²

     I = 221.4 (4.435 10⁻⁹)

     I = 9.82 10⁻⁷ W / m²

What do you need to calculate the speed of sound
lbvjy [14]

Answer:

so that at temperature C = F, the speed of sound is m/s = ft/s = mi/hr. This calculation is usually accurate enough for dry air, but for great precision one must examine the more general relationship for sound speed in gases.

An uncharged capacitor is connected to the terminals of a 4.0 V battery, and 9.0 μC flows to the positive plate. The 4.0 V batte
Lelechka [254]

Answer:

2.25\mu C

Explanation:

At the beginning, we have:

V = 4.0 V potential difference across the capacitor

Q=9.0 \mu C=9.0\cdot 10^{-6}C charge stored on the capacitor

Therefore, we can calculate the capacitance of the capacitor:

C=\frac{Q}{V}=\frac{9.0 \cdot 10^{-6} C}{4.0 V}=2.25\cdot 10^{-6} F

Later, the battery is replaced with another battery whose voltage is

V = 5.0 V

Since the capacitance of the capacitor does not change, we can calculate the new charge stored:

Q=CV=(2.25\cdot 10^{-6} F)(5.0 V)=11.25 \cdot 10^{-6} C=11.25 \mu C

Since the capacitor has been connected exactly as before, we have that the charge on the positive plate has increased from 9.0 \mu C to 11.25 \mu C. Therefore, the additional charge that moved to the positive plate is

\Delta Q = 11.25 \mu C-9.0 \mu C=2.25 \mu C
