Aunque la interacción entre Placas Tectónicas es la principal causa de los sismos no es la única. Cualquier proceso que pueda lograr grandes concentraciones de energía en las rocas puede generar sismos cuyo tamaño dependerá, entre otros factores, de qué tan grande sea la zona de concentración del esfuerzo. Las causas más generales se pueden enumeran según su orden de importancia en:

TECTÓNICA: son los sismos que se originan por el desplazamiento de las placas tectónicas que conforman la corteza, afectan grandes extensiones y es la causa que más genera sismos.

VOLCÁNICA: es poco frecuente; cuando la erupción es violenta genera grandes sacudidas que afectan sobre todo a los lugares cercanos, pero a pesar de ello su campo de acción es reducido en comparación con los de origen tectónico.

HUNDIMIENTO: cuando al interior de la corteza se ha producido la acción erosiva de las aguas subterráneas, va dejando un vacío, el cual termina por ceder ante el peso de la parte superior. Es esta caída que genera vibraciones conocidas como sismos. Su ocurrencia es poco frecuente y de poca extensión.

DESLIZAMIENTOS: el propio peso de las montañas es una fuerza enorme que tiende a aplanarlas y que puede producir sismos al ocasionar deslizamientos a lo largo de fallas, pero generalmente no son de gran magnitud.

EXPLOSIONES ATÓMICAS: realizadas por el ser humano y que al parecer tienen una relación con los movimientos sísmicos.

One baked potato provides an average of 30 mg of vitamin C. If 70 potatoes weigh 20 lb., how many milligrams of vitamin C are pr
JulsSmile [24]

Answer:

105 mg

Explanation:

Given that:

1 baked potato provides 30 mg of vitamin C.

So,

70 baked potatoes provide 30\times 70 mg of vitamin C

Also,

70 potatoes = 20 lb

So,

20 lb potatoes provide 30\times 70 mg of vitamin C

Thus,

1 lb potatoes provide \frac {30\times 70}{20} mg of vitamin C

<u>Thus, 105 mg of Vitamin C are provided per pound of the potatoes.</u>

"5 N, up" is an example of a ___.<br> OA) force<br> OB) mass<br> OC) weight<br> OD) magnitude
Sunny_sXe [5.5K]

Answer:

A) Force

Explanation:

It is an example of force since force is a vector quantity so it has magnitude and direction. In this case the magnitude is equal to 5 [N] and the direction is upward.

The weight can not be, as it always acts downward.

Mass is not a force, its unit is given usually in kilogram [kg]

A satellite that goes around the earth once every 24 hours (86,400 s) is called a geosynchronous satellite. If a geosynchronous
Olegator [25]

Answer:

42244138.951 m

Explanation:

G = Gravitational constant = 6.667 × 10⁻¹¹ m³/kgs²

r = Radius of orbit from center of earth

M = Mass of Earth = 5.98 × 10²⁴ kg

m = Mass of Satellite

The satellite revolves around the Earth at a constant speed

Speed = Distance / Time

The distance is the perimeter of the orbit

v=\frac{2\pi \times r}{24\times 3600}

The Centripetal force of the satellite is balanced by the universal gravitational force

m\frac{v^2}{r}=\frac{GMm}{r^2}\\\Rightarrow \frac{\left(\frac{2\pi \times r}{24\times 3600}\right)^2}{r}=\frac{6.667\times 10^{-11}\times 5.98\times 10^{24}}{r^2}\\\Rightarrow \left(\frac{2\pi \times r}{24\times 3600}\right)^2=6.667\times 10^{-11}\times 5.98\times 10^{24}\\\Rightarrow r^3=\frac{6.667\times 10^{-11}\times 5.98\times 10^{24}\times (24\times 3600)^2}{(2\pi)^2}\\\Rightarrow r=\left(\frac{6.667\times 10^{-11}\times 5.98\times 10^{24}\times (24\times 3600)^2}{(2\pi)^2}\right)^{\frac{1}{3}}\\\Rightarrow r=42244138.951\ m

The radius as measured from the center of the Earth) of the orbit of a geosynchronous satellite that circles the earth is 42244138.951 m

What is a control,constant, independent variable, and a dependent variable in a science experiment?
vagabundo [1.1K]
A control is something you don't touch/change in a exprement, a constant is the same as the control, the independent is the one the you do vhange, the dependet is the one that you observe/ use your 5 sences with.
