Two 50-μm-wide slits spaced 0.25 mm apart are illuminated by blue laser light with a wavelength of 450 nm. The interference pattern is observed on a screen 2.0 m behind the slits.
How many bright fringes are seen in the central maximum that spans the distance between the first missing order on one side and the first missing order on the other side?
Answer:
your answer is 5.45 that is your answer
The number of 9 bright fringes is seen in the central maximum that spans the distance between the first missing order is 5 on one side and the first missing order on the other side
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
Blue laser light with a wavelength of 450 nm illuminates two 50-m-wide slits positioned 0.25 mm apart. On a screen 2.0 m behind the slits, the interference pattern is visible.
For dark fringe, the equation as:
yp = p λ L / d
for p =1
yp = λ× L/a
For bright fringe, the equation as:
ym = m λL / d
from (i) and (ii)
For missing order, the equation as:
ym = yp
m λL / d = λ× L/a
m=d/a
m = 0.25×10⁻³/ (50×10⁻⁶)
m=5
The number of bright fringes, the equation as:
N-1=2(m-1)
N-1 = 2×4
N = 8 + 1
N=9

slope of (-8,-3) (-1,-2)
Answer:
(1,2) , (3,8)
Slope is equal to the change in y
over the change in x
, or rise over run.
m=change in ychange in x
The change in x
is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).
m=y2−y1x2−x1

Step-by-step explanation:
2 hours=26 gallons or 2:26
We should simplify the ratio to see how many gallons an hour flight uses.
26÷2=13 or 13 gallons
1 hour=13 gallon
Now we see how much gas a 5-hour flight takes.
5x13=65
5 hours=65 gallons

simplify, the fraction 12/18
Answer:
23
Step-by-step explanation:
Since 12 and 18 are both divisible by 3, you would divide them by 3. Then, you are left with the fraction 46 . But, since 4 and 6 are both divisible by 2, you would do that. Finally, you end up with 23 with is in the lowest terms.

Solve for the value of r.
Answer:
r=14
Step-by-step explanation:
7r+6=8r-8
14=r
r=14
Answer:
r = 14
Step-by-step explanation:
Since both angles are equivalent to each other solve for r:
7r + 6 = 8r - 8 (subtract 6 from -8)
7r = 8r - 14 (subtract 8r from 7r)
-r = -14 (divide each side by -1)
r = 14
Then plug the value of r (14) back into both parentheses:
7 * 14 + 6 = 104°
8 * 14 - 8 = 104°
The final answer is r = 14, and both angles equal to 104°

Answer:
Step-by-step explanation:

a^0 = 1 if a is not 0
9. 3^(-2)
= 1/3^2
= 1/9
11. (-5)^(-2)

= 1/1*1/25
= 1/25
15. -3^0 = 1
17. 1/2^0
= 1/1
=1
26. k^(-4)*j^0
=(1/k^4)*1
=1/k^4
36. 7*s^0*t^(-5) / 2^(-1)*m^2
= 7*1*(1/t^5) / (1/2)*m^2
= 2*7 / t^5*m^2
= 14 / t^5*m^2
Factor the difference of two perfect squares using the X method. An x-method chart shows the product a c at the top of x and b at the bottom of x. What are the two binomial factors for x2 – 25? (x – 5)(x – 5) (x 5)(x 5) (x – 20)(x 5) (x – 5)(x 5).
By using x-method we got that factorization [tex]x^2-25[/tex] is (x+5)(x-5)
What is factorization ?factorization is writing a expression as a product of several factors.
So Given polynomial is
[tex]x^2-25[/tex]
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
[tex]x^2-5x+5x-25\\\\x(x-5)+5(x-5)\\\\(x+5)(x-5)[/tex]
By using x-method we got that factorization [tex]x^2-25[/tex] is (x+5)(x-5)

Answer:
The 90% confidence interval would be given by (63.330;81.070)
Step-by-step explanation:
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Let put some notation
x=left arm , y = right arm
x: 175 169 182 146 144
y: 102 101 94 79 79
Since the Confidence is 0.90 or 90%, the value of a = 0.1 and a/2= 0.05we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,4)".And we see that ta/2= 2.13
