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.
Answer:
m=243/4 when v=9.
Step-by-step explanation:
We know that when y varies directly with x², the formula of direct proportion is
where 'k' is the constant of variation.
so
As m varies directly with v², and m=3 when v=2
m=kv²
k=m/v²
= 3/(2)²
=3/4
Hence, k=3/4
so when v=9 then the expression becomes
m=kv²
substituting v=9 and k=3/4
m= 3/4(9)²
=3/4 × 81
=243/4
Therefore, m=243/4 when v=9.
A. 4x - y = 8
y = -8 y-int (0,-8)
x = 2. x-imt (2,0)
b. 6x - y = -3
x = -1/2 (-1/2, 0) x int
y = 3 : (0,3) y-intercept
c. x = -5 x-int (-5,0)
y -int (0,25) y = 25
Arron score 1/2
Lauren scored 6/8 or 3/4
3/4 is larger than 1/2 so Lauren scored on more of her attempted goals than Arron did which makes her more successful.
