Indicar objetosque puedan ser observados a simple vista, con microscopio, con microscopio electrico y con miscroscopio de transm
AysviL [449]

Answer:

En esta respuesta voy a usar la unidad μm, tal que:

1 μm = 1*10^(-9) m

Objetos que pueden ser observados a simple vista:

Son todos aquellos objetos que podemos observar simplemente con nuestros ojos, con ellos podemos observar desde un edificio (con tamaños de decenas de metros) hasta algunos cabellos, que pueden tener un diámetro de 0.1 mm

Cosas más pequeñas que estás muy difícilmente se pueden ver a simple vista.

Con un microscopio podremos ver cosas del tamaño de una célula, como glóbulos blancos, rojos, algunos microorganismos, etc, los cuales rondan un tamaño de unos 10 μm. Naturalmente, distintos microscopios tendrán distintas amplificaciones (por lo que con algunos podremos ver objetos muy pequeños que con otros no).

Microscopio eléctrico:

Este microscopio usa electrones en lugar de luz para formar imágenes.

Con él podremos observar cosas como las componentes de una célula (membranas, orgánulos grandes, etc), los cuales pueden medir unos pocos nanómetros (por ejemplo, una membrana celular tendrá un tamaño de entre 5 μm y 10 μm)

Microscopio de transmisión.

Tener en cuenta que el microscopio de transmisión es un microscopio eléctrico, el cual lanza un haz de electrones al objeto que se desea observar, de tal forma que algunos de estos electrones rebotan formando así la imagen virtual amplificada que podemos observar.

Con estos aparatos podemos ver orgánulos pequeños (0.5 μm), y lo más pequeño que podemos ver (con los microscopios más potentes) son columnas de átomos (0.1 μm)

Why are you able to make someone on a swing have very large swings by only exerting very small forces on them?
Allisa [31]
Because almost all of the force is done by the weight of the person and the mechanism of the swing itself, when you push someone you only give them an increase in velocity, the acceleration comes from the weight at first and then from gravity when the person is coming down, which is why we bend our legs when coming down

An anchor with a density of 700 lb/ft3 tied to a rope is submerged in water (but is not touching the bottom). It has a volume of
Ivanshal [37]

Answer:

Explanation:

Given

Density of anchor \rho _a=700\ lb/ft^3

Volume of anchor V=2.8\ ft^3

Density of water \rho _w=62.4\ lb\ft^3

Buoyancy force on submerged object is given by

F_B=\rho _W\times V\times g

F_B=62.4\times 2.8\times 32.2=5625.98\approx 5626\ approx lbf

Explain why incremental development is the most effective approach for developing business software systems. Why is this model l
Ksenya-84 [330]

Explanation:

Typically, business software technologies are complex, and software strenuous. Business software applications are also often upgraded for changes in business goals or procedures. Real-time systems usually require a lot of hardware components that are quite difficult to change and cannot be upgraded Usually, actual-time safety critical systems that required to be built based on well-planned processes.
