Identify the procedure to determine a formula for self-inductance, or inductance for short. Using the formula derived in the tex
kompoz [17]

Answer:

L = 0.0319 H

Explanation:

Given that,

Number of loops in the solenoid, N = 900

Radius of the wire, r = 3 cm = 0.03 m

Length of the rod, l = 9 cm = 0.09 m

To find,

Self inductance in the solenoid

Solution,

The expression for the self inductance of the solenoid is given by :

L=\dfrac{\mu_o N^2 A}{l}

L=\dfrac{4\pi\times10^{-7}\times(900)^{2}\times\pi(0.03)^{2}}{0.09}

L = 0.0319 H

So, the self inductance of the solenoid is 0.0319 henries.

a kid is on a skate board going 14kph and trows a set of keys on the ground at 8kph. the spped of the keys relitive to the gound
Vanyuwa [196]
To determine the speed relative to the ground, since the ground is our reference frame, it would be v = 0, for the kid on the skateboard, you would need to take into account the speed that he/she is going and the speed of the keys thrown at.

I believe.

un bus sale de florencia hacia el municipio de san vicente del caguan con una velocidad de 30km/h. 2 horas mas tarde sale otro b
goldenfox [79]
Recuerda que distancia=velocidad x tiempo (d=vt). vamos a llamar d _{1} a la distancia que reccore el primer bus, y d _{2} la distancia que recoore el segundo. Los se econtraran cuando la ditancia recorrida por cada bus sea la misma, es decir d _{1} =d _{2}.
Ahora sabemos que la velocidad del primer bus es 30 km/h y su tiempo es t; en cuanto al segundo bus, su velocidad es 45 km/h y como sale 2 horas mas tarde su tiempo será t-2. Ahora podemos reemplazar los valores en nuestra ecuación de de distanica para hallar el tiempo:
30t=45(t-2)
30t=45t-90
30t-45t=-90
-15t=-90
t= \frac{-90}{-15}
t=6
Los buses se encontraran en 6 horas, 4 horas después de haber salido el segundo bus.

 Ahora para hallar la distancia a la que los buses estaran de <span>san vicente del caguan solo necesitaremos reemplazar la el tiempo en nuestra equación de distancia para el primer bus:
</span>d _{1} =(30)(6)
d _{1} =180
<span>En el punto de encuentro los buses estarán a 180 km de San Vicente del Caguan.

Explain how do global winds impact weather in an area?
PolarNik [594]

Answer:

As the warmer air over the equator rises, colder air from the poles rushes toward the equator to take its place. Global winds push air masses around Earth and bring changes in the weather. In the United States, global winds called the prevailing westerlies push air masses from west to east.
