Answer:

Hey

(note you have forgotten your diagram so this may not be what you where hoping for.)

The important discovery that galilao made was that he proved that <em><u>all objects no matter their mass fall at the same rate.</u></em>

That is to say that a bowling ball falls at the same rate as a truck.

You are trying to overhear a most interesting conversation, but from your distance of 10.0 m , it sounds like only an average wh
Alexandra [31]

Answer:

r₂=0.1 m

Explanation:

Given that

r₁= 10 m  , β₁ = 20 dB

At r₂ ,β₂= 60 dB

As we know that intensity level of sound given as

\beta =10\ log\dfrac{I}{10^{-12}}

\beta _1=10\ log\dfrac{I_1}{10^{-12}}

20=10\ log\dfrac{I_1}{10^{-12}}

10² x 10⁻¹² = I₁

I₁=10⁻¹⁰ W/m²

\beta _2=10\ log\dfrac{I_2}{10^{-12}}

60=10\ log\dfrac{I_1}{10^{-12}}

10⁶ x  10⁻¹² = I₂

I₂ = 10⁻⁶ W/m²

I₁=10⁻¹⁰ W/m²

P = I A

P=Power ,I =Intensity  ,A=Area

\dfrac{I_1}{I_2}=\dfrac{r^2_2}{r^2_1}

\dfrac{10^{-10}}{10^{-6}}=\dfrac{r^2_2}{10^2}

r₂=0.1 m

A 100-m long transmission cable is suspended between two towers. If the mass density is 2.01 kg/m and the tension in the cable i
Inga [223]

Answer:

The speed  is v  =122.2 \ m/s

Explanation:

From the question we are told that

   The  length of the wire is L  =  100 \ m

    The  mass density is  \mu =  2.01 \ kg/m

    The tension is T  =  3.00 *10^{4} \ N

   

Generally the speed of the transverse cable is mathematically represented as

           v  = \sqrt{\frac{T}{\mu} }

substituting values

         v  = \sqrt{\frac{3.0 *10^{4}}{2.01} }

        v  =122.2 \ m/s
