10. True or False. Subduction zones formed the Aleutian Islands.

Physics
1 answer:
Licemer1 [7]2 years ago
5 0

Answer:

True

Explanation:

How were the aleutian islands formed? In southwestern Alaska, those two plates meet head on, and the Pacific plate sinks beneath the North American plate. In this subduction zone, some of the ocean plate melts and the molten rock pushes to the surface in a string of 40 active volcanoes, forming the Aleutian Islands.

A crane exerts a net force of 900 N upward on a 750-kilogram car as the crane starts to lift the car from the deck of a cargo sh
melisa1 [442]

Answer: 1.2m/s^2

Explanation: the force exerted on the car is 900N upwards

The mass of the car is 750kg

According to Newton's third law acceleration is proportional to force

F = ma

900 = 750a

a = 900/750

a = 1.2m/s^2

Would a limestone building weather more rapidly in Homer, Alaska, or in Honolulu, Hawaii? Explain your reasoning.
Vinvika [58]
Hawaii for sure. 

Well, Hawaii is hot (most of the time I think) and Alaska is always freezing (or at least cold). So hawaii.

12. A las 10 de la mañana Elena sale a 100 Km/h de una ciudad A con dirección a Madrid. A la misma hora sale Javier desde otra c
Klio2033 [76]

Answer:

a) t = 3.3 [h]

b ) Hora = 13:18 o 1:18 [pm]

c) x = 327.79 [km/h] (Elena)

x = 196.6 [km] (Javier)

Explanation:

Para poder solucionar este problema debemos hacer un planteamiento inicial de ubicacion de las ciudades, este planteamiento nos ayudara a entender el problema de una manera mas facil.

Tenemos las ciudades A & B y la ciudad de Madrid que esta a una distancia x con respecto de B, (ver esquema adjunto).

De manera logica debemos deducir que la Ciudad A debe estar mas lejos de Madrid que la ciudad B de la misma Madrid, ya que en caso contrario Javier nunca alcanzara a Elena, ya que Elena va mas rapido que Javier.

a) Ahora debemos de utilizar la siguiene ecuacion de la cinematica, cuando los cuerpos se mueven a velocidad constante.

x=x_{o}+v*t

Donde:

x -xo = Distancia entre el punto inicial y punto final.

v = velocidad [m/s]

t = tiempo [s]

Debemos convertir las velocidades de kilometros por hora a metros por segundo.

100 [\frac{km}{h} ]*1[\frac{h}{3600s}]*1000[\frac{m}{1km} ] = 27.77[m/s]\\60[\frac{km}{h} ]*1[\frac{h}{3600s}]*1000[\frac{m}{1km} ] = 16.66[m/s]

Seguidamente formulamos una ecuacion por cada movimiento, luego debemos igualar estas ecuaciones en funcion de la variable x que sera el punto donde se encuentren ambas personas.

<u>Para Elena</u>

(132000+x) = 27.77*t\\x = 27.77*t - 132000

<u>Para Javier</u>

<u />x - xo = 16.66*t\\xo = 0\\x = 16.66*t<u />

Igualamos las variables x de ambas ecuaciones.

16.66*t = 27.77*t -132000\\27.77*t - 16.66*t = 132000\\11.11*t = 132000\\t = 11880.83 [s] = 3.3 [h]

b) La hora facilmente se puede encontrar sumando el tiempo con las 10:00am

hora = 10 + 3 = 13 [hrs]

La parte decimal debe convertirse a tiempo.

0.3 [hr]*60[\frac{min}{1hr} ]= 18 min

Hora = 13:18 o 1:18 [pm]

c) Para encontrar estas distancias utilizamos el tiempo encontrado en el item a.

<u>Para Elena</u>

x = v*t\\x = 27.77*11800.83 = 327791.6 [m] = 327.79 [km]\\

<u>Para Javier</u>

<u />x = v*t\\x = 16.66*11800.83 = 196601.8 [m] = 196.6 [km]<u />
