Que significa matematicamente que se ha debilitado en promedio un 5% el campo magnetico terrestre?

Physics
1 answer:
Neko [114]3 years ago

Answer:

Significa que, por el efecto Dynamo, la longitud del solenoide del que se deriva el magnetismo ha aumentado en un 5% en promedio en comparación con el efecto combinado del producto del número de caminos eléctricos y la corriente eléctrica dividida en el núcleo de la Tierra de modo que el mecanismo esté cambiando de modo que los polos norte y sur cambien de lugar

Explanation:

Por el cual el campo magnético de la Tierra se debe al efecto Dynamo que tenemos por simple analogía, la intensidad del campo magnético, B_c, hacia el centro de la fuente del campo magnético de la Tierra está dada por la relación;

Intensidad del campo magnético, B_c

B_c = \dfrac{\mu _0 \cdot I  \cdot N}{L}

Dónde:

B_c = Intensidad del campo magnético

μ₀ = Permeabilidad del espacio libre = Constante

N = Número de vueltas del conductor de corriente

L = longitud del solenoide

Si la fuerza del campo magnético, B_c, está aumentando, indica que

N e I disminuyen mientras L aumenta

Dado que la forma de la Tierra se aplana en los polos y las protuberancias en el ecuador, podría significar que, como se observó, los polos se están invirtiendo, lo que da la probabilidad de que cambie la orientación desde la inclinación del polo hacia el ecuador.

A plank of length L=2.200 m and mass M=4.00 kg is suspended horizontally by a thin cable at one end and to a pivot on a wall at
baherus [9]

Hello!

Let's begin by doing a summation of torques, placing the pivot point at the attachment point of the rod to the wall.

\Sigma \tau = 0

We have two torques acting on the rod:
- Force of gravity at the center of mass (d = 0.700 m)

- VERTICAL component of the tension at a distance of 'L' (L = 2.200 m)

Both of these act in opposite directions. Let's use the equation for torque:
\tau = r \times F

Doing the summation using their respective lever arms:

0 = L Tsin\theta  - dF_g

dF_g = LTsin\theta

Our unknown is 'theta' - the angle the string forms with the rod. Let's use right triangle trig to solve:

tan\theta = \frac{H}{L}\\\\tan^{-1}(\frac{H}{L}) = \theta\\\\tan^{-1}(\frac{1.70}{2.200}) = 37.69^o

Now, let's solve for 'T'.

T = \frac{dMg}{Lsin\theta}

Plugging in the values:
T = \frac{(0.700)(4.00)(9.8)}{(2.200)sin(37.69)} = \boxed{20.399 N}

Naddik [55]

Answer:

d. lower than the original pitch and decreasing as he falls.

Explanation:

As per the Doppler effect when the pitch of the sound increases as the source approaches the observer and decreases as the source moves away. A classic example of this increasing pitch of ambulance siren as it approaches you and decreasing pitch of the siren as it goes away from you.

The same effect is applicable here as well. As the character keep falling, it is moving away from the observer so the pitch of his scream will keep on decreasing.
