Answer:
Colors appear differently. Different light sources give off different rays that affect the color
The shoppers often take clothes outside to look at them in daylight before deciding whether to buy them because they can see the true color of the clothes only in sunlight where no bulb light is reflecting on the clothes.
What is reflection?A wave will rapidly reverse course and reflect when it hits a barrier between two media. At least a portion of the oncoming wave disturbance remains in the same medium. Regular reflection occurs at plane boundaries in accordance with a simple law.
The angle of incidence, or the angle between the motion of an approaching wave and a perpendicular to the reflecting surface, is equal to the angle between the motion of a reflected wave and a perpendicular (angle of reflection).
The shoppers often take clothes outside to look at them in daylight before deciding whether to buy because the color is true in pure sunlight, the room light, or bulb light the color will appear true.

A bowling ball moving with a velocity of 5V to the right collides elastically with a beach ball moving at a velocity 2V to the left. The bowling ball barely slows down. What is the approximate velocity of the beach ball after the collision?
Answer:
[tex]v'_2=3V[/tex]
Explanation:
From the question we are told that:
Bowling ball Speed [tex]v_1=5 m/s[/tex]
Beach ball Speed [tex]v_2=2 m/s[/tex]
Let The Mass be equal i.e
[tex]M_1=M_2[/tex]
Therefore
Generally the equation for Velocity of beach ball after collision [tex]v'_2[/tex] is mathematically given by
Since Velocity is Vector Quantity
Therefore
[tex]v'_2=v_1-v_2[/tex]
[tex]v'_2=5-2[/tex]
[tex]v'_2=3V[/tex]

una llamada telefonica a brasil de 4 minutos costo el mes pasado 2430 si el valor por minuto se mantiene cualto debo pagar por una llamada de 6 minutos a ese pais
Answer:
Costo = 3645
Explanation:
Dados los siguientes datos;
Costo de la llamada = 2430
Duración = 4 minutos
En primer lugar, encontraríamos el costo por minuto;
Costo por minuto, Cpm = 2430/4
Cpm = 607.5
A continuación, para encontrar el costo de 6 minutos;
Costo = 607,5 * 6
Costo = 3645

Si está probando u motor para un nuevo modelo de coche ; este es capaz de pasar de 0 a 100 km/h en 7,5 segundos . Si el coche tiene una masa de 550 kg cuál será la fuerza que realiza el motor ?
Answer:
La fuerza que realiza el motor es 2035 N.
Explanation:
Podemos encontrar la fuerza del motor usando la siguiente ecuación:
[tex] F = ma [/tex] (1)
En donde:
m: es la masa del coche = 550 kg
a: es la aceleración
Se puede calcular la aceleración mediante la siguiente ecuación cinemática:
[tex] v_{f} = v_{0} + at [/tex] (2)
En donde:
[tex] v_{f}[/tex]: es la velocidad final del coche = 100 km/h
[tex] v_{0} [/tex]: es la velocidad inicial del coche = 0
t: es el tiempo = 7,5 s
Resolviendo la ecuación (2) para "a" tenemos:
[tex] a = \frac{v_{f} - v_{0}}{t} = \frac{100\frac{km}{h}*\frac{1000 m}{1 km}*\frac{1 h}{3600 s} - 0}{7,5 s} = 3,70 m/s^{2} [/tex]
Entonces, la fuerza es:
[tex] F = ma = 550 kg*3,70 m/s^{2} = 2035 N [/tex]
Por lo tanto, la fuerza que realiza el motor es 2035 N.

4-year-old becomes frightened of the dark and refuses to go to sleep at night. How would a psychoanalyst and a behaviorist differ in their views of how this problem developed?
Answer:
A psychoanalyst would see the 4-year-old as having an unresolved conflict where the brain judges or evaluates how good or bad the darkness is, or the usefulness of sleeping in the dark at night based on a comparison, due to the child's exploration of the world around him. A psychoanalyst might see the child's refusal to sleep at night due to the dark as a fear created for instance when the child sleeps alone without the parent. This might change if the child sleeps at night beside the parent in the dark.
While behaviorists would look at how having previous negative experiences in the dark influences a child's behavior towards staying in the dark. This fear would be reinforced with more negative experiences in the dark such as having a bad nightmare whenever the child sleeps in the dark, a feeling of hearing, or seeing strange things while in the dark. These examples would have built a behavioral pattern where the child would be conditioned to respond fearfully to being in the dark.

Indicar objetosque puedan ser observados a simple vista, con microscopio, con microscopio electrico y con miscroscopio de transmicion. Indicar cuel es orden de magnitud de cada uno
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)
