Answer:

Explanation:

Three types of metals interact with magnetic fields: ferromagnetic, paramagnetic and diamagnetic metals. Ferromagnetic metals are strongly attracted to magnets; the rest are not. Magnets also attract paramagnetic metals, but very weakly. Diamagnetic metals repel the magnet, though the force is typically very weak.

What is the intensity of a sound with a sound intensity level (SIL) 67 dB, in units of W/m^2?

vfiekz [6]

Answer:

The intensity of sound (I) = 3.16 x 10⁻⁶ W/m²

Explanation:

We have expression for sound intensity level (SIL),

$L=10log_{10}\left ( \frac{I}{I_0}\right )$

Here we need to find the intensity of sound (I).

$L=10log_{10}\left ( \frac{I}{I_0}\right )\\\\log_{10}\left ( \frac{I}{I_0}\right )=0.1L\\\\\frac{I}{I_0}=10^{0.1L}\\\\I=I_010^{0.1L}$

Substituting

L = 67 dB and I₀ = 10⁻¹² W/m² in the equation

$I=I_010^{0.1L}=10^{-12}\times 10^{0.1\times 65}\\\\I_0=10^{-12}\times 10^{6.5}=10^{-5.5}=3.16\times 10^{-6}W/m^2$

The intensity of sound (I) = 3.16 x 10⁻⁶ W/m²

How long must a simple pendulum be if it is to make exactly one swing per second? (That is, one complete vibration takes exactly

umka2103 [35]

Oscillation is a type of periodic motion which repeats itself to and from about a point which is called mean position. The period of a Pendulum can be described as a ratio between the length and gravity as,

$T = 2\pi \sqrt{\frac{L}{g}}$

Here,

L = length

g = Gravity

If we rearrange to find the length we have that,

$L = \frac{T^2g}{4\pi^2}$

Our period is 2s and the gravity is 9.8m/s^2, then,

$L = \frac{(2)^2(9.8)}{4\pi^2}$

$L = 0.9929m$

The simple required length of the pendulum must be 0.9929m
