How many electrons are available for bonding in oxygen

A middle-aged man typically has poorer hearing than a middle-aged woman. In one case a woman can just begin to hear a musical to

Dmitriy789 [7]

Answer:

4

Explanation:

$I_0$ = Threshold intensity for woman

I = Intensity of sound for man

$\beta$ = Intensity level of sound = 6 dB

Intensity level of sound is given by

$\beta=10log\dfrac{I}{I_0}\\\Rightarrow 6=10log\dfrac{I}{I_0}\\\Rightarrow \dfrac{6}{10}=log\dfrac{I}{I_0}\\\Rightarrow 10^{\dfrac{6}{10}}=\dfrac{I}{I_0}\\\Rightarrow \dfrac{I}{I_0}=10^{\dfrac{6}{10}}\\\Rightarrow \dfrac{I}{I_0}=10^{0.6}\\\Rightarrow \dfrac{I}{I_0}=3.98\approx 4$

The ratio is 4

To practice problem-solving strategy 26.1 resistors in series and parallel. two bulbs are connected in parallel across a source

hichkok12 [17]

Emf e = 11
r 1 = 3.0
r 2 = 3.0
r 3 = ?

The two in parallel are equivalent to 3 • 3/6 = 1.5 Ω
To have 2.4 volts across them, the current is I = 2.4/1.5 = 1.6 amps. and the unknown R = (11–2.4) / 1.6 = 5.375 Ω or 5.4 Ω
