The distance between the first and second dark lines of the interference pattern is mathematically given as
d= 0.107 m
<h3>What is the distance between the first and second dark lines of the interference pattern?</h3>Question Parameters:
Two very narrow slits are spaced 1.80 mm apart and are placed 35.0 cm from a screen
coherent light with 550 nm
Generally, the equation for the distance between the first and second dark lines is mathematically given as
Therefore
d= 550*10^-9*0.35/(1.8*10^-6)
d= 0.107 m
In conclusion, the distance between the first and second dark lines
d= 0.107 m

Answer:
b)1 :3
Explanation:
Lets that
The value of a positive charge = q
As we know that electric filed on a point charge given as
Where ,K=Constant
q=Charge ,r=Distance
If the value of the charge gets tripled ,q'= 3 q
Then electric filed E'
E' = 3 E
Therefore we can say that
therefore the answer will be --
b)1 :3
Answer:
Part a)
Part b)
Explanation:
As we know that torque is defined as the product of force and its perpendicular distance from reference point
so here we have
now we have
Part b)
Now we know the conversion as
1 meter = 3.28 foot
1 N = 0.225 Lb force
now we have
