Answer:

DE HECHO EL SONIDO DÍ PUEDE ATRAVESAR LAS PAREDES, PERO

CUANDO ENTRA EN LA PARED, EL SONIDO VIAJA MÁS RÁPIDO QUE EN EL

AIRE Y CUANDO SALE DEL OTRO LADO, EL SONIDO VA A UNA

VELOCIDAD ALTA, POR ESTO LSA VOCES SE ESCUCHAN AUNQUE NO

MUY CLARAS.

A 259-kV power transmission line carrying 429 A is hung from grounded metal towers by ceramic insulators, each having a 0.71×109
ella [17]

Answer:

The resistance is 7.47\times10^{6}\ \Omega.

Explanation:

Given that,

Power = 259 kV

Current = 429 A

Resistance R=0.71\times10^{9}\ Omega

We need to calculate the current in each insulator

Using formula of current

I=\dfrac{P}{R}

Put the value into the formula

I=\dfrac{259\times10^{3}}{0.71\times10^{9}}

I=3.64\times10^{-4}\ A

So all 95 insulators are in parallel

We need to calculate the resistance

Using formula of resistance

\dfrac{1}{R}=\sum_{i=1}^{95}\dfrac{1}{R_{i}}

Put the value into the formula

\dfrac{1}{R}=\dfrac{95}{0.71\times10^{9}}

\dfrac{1}{R}=1.338\times10^{-7}

R=\dfrac{1}{1.338\times10^{-7}}

R=7473841.5=7.47\times10^{6}\ \Omega

Hence, The resistance is 7.47\times10^{6}\ \Omega.

Determine the kinetic energy of a 625-kg roller coaster car that is moving with a speed of 10 m/s.
abruzzese [7]

Hi there!

Kinetic energy can be calculated using the following:

\large\boxed{KE = \frac{1}{2}mv^2}}

Where:

KE = Kinetic energy (J)

m = mass (kg)

v = velocity (m/s)

Plug in the given values:

KE = \frac{1}{2}(625)(10^2) = \boxed{31250J}
