A quantum object whose state is given by is sent through a Stern-Gerlach device with the magnetic field oriented in the y-direct
Ahat [919]

Answer:

The probability that the object will emerge from the + side of this device is 1/2

Step-by-step explanation:

Orienting the magnetic field in a Stern-Gerlach device in some direction(y - direction) perpendicular to the direction of motion of the atoms in the beam, the atoms will emerge in two possible beams, corresponding to ±(1/2)h. The positive sign is usually referred to as spin up in the direction, the negative sign as spin down in the explanation, the separation has always been in the y direction. There can be some other cases where magnetic field may be orientated in x-direction or z-direction.

How do I find the x and y intercepts from two given points?<br><br> (-7,6),(-4,11)
V125BC [204]

Answer:

the desired x-intercept is (-53/5, 0); the y-intercept is  (0, 53/3).

Step-by-step explanation:

Find the equation of the line through the given points first:

As we move from (-7,6) to (-4,11), x increases by 3 and y by 5.

Thus, the slope of this line is m = rise / run = 5/3.

Use the slope-intercept formula y = mx + b.  Substitute 5/3 for m, 6 for y and -7 for x:

6 = (5/3)(-7) + b, where b is the y-coordinate of the y-intercept:

6 = -35/3 + b, or 18/3 = -35/3 + b.  Adding 35/3 to both sides, we get:

53/3 = b.

Then the y-intercept is (0, 53/3).

To find the x-intercept, let y = 0 and solve the resulting equatin for x:

0 = (5/3)x + 53/3, or 0 = 5x + 53.  Then x = -53/5, and the desired x-intercept is (-53/5, 0).

2.49 Encuentre los errores en cad uno de las siguientes aseveraciones: a) las probabilidades de que un vendedor de automóviles v
Yuki888 [10]

Answer:

Step-by-step explanation:

a) Si se suman las probabilidades de venta, es decir:

Probabildad de vender 0 auto ( es decir que no vendió) = 0,19

Probabildad de vender 1 auto                                              = 0,38

Probabildad de vender 2 autos                                            = 0,29

Probabildad de vender 3 autos                                            =0,15

Da por resultado:  1,01

1,01 > 1  

Ninguna probabilidad puede ser mayor que

b) LLover y no llover son condiciones excluyentes en relación al evento, es decir en relación a lluvia cualquier día o llueve o no llueve de tal forma

que las dos situaciones conforman el universo completo y deben sumar 1. en este caso el error s que suman 0.92 cando deberían sumar 1

c) No existen probabilidades negativas ( en este caso señalan -0,25 como una probabilidad

d) La probabilidad de sacar una carta de corazones es 1/4 (correcta pues hay la misma cantidad de carta de las cuatro viras  tipo ( diamante, trebo, corazones y el otro).

La mitad de las cartas son negras, de tal modo que 1/2 es correcto valor para esta probabilidad.

La probabilidad de que sea corazones y negra s 1/4*1/2  = 1/8

Luego no hay error en esta aseveración
