At what angle does a diffraction grating produce a second-order maximum for light having a first-order maximum at 20.0 degrees?

Answers

Answer:

At 43.2°.

Step-by-step explanation:

To find the angle we need to use the following equation:

[tex] d*sin(\theta) = m\lambda [/tex]

Where:

d: is the separation of the grating

m: is the order of the maximum

λ: is the wavelength

θ: is the angle              

At the first-order maximum (m=1) at 20.0 degrees we have:

[tex] \frac{\lambda}{d} = \frac{sin(\theta)}{m} = \frac{sin(20.0)}{1} = 0.342 [/tex]

Now, to produce a second-order maximum (m=2) the angle must be:

[tex] sin(\theta) = \frac{\lambda}{d}*m [/tex]

[tex] \theta = arcsin(\frac{\lambda}{d}*m) = arcsin(0.342*2) = 43.2 ^{\circ} [/tex]

Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.    

I hope it helps you!                                                        

Last week, Kira drove 291 miles. This week, she drove n miles. Using n, write an expression for the total number of miles she drove in the two weeks.

Answers

Answer:

d = 291 + n

Step-by-step explanation:

Given that,

Last week, Kira drove 291 miles. Then this week she drove n miles.

We need to find an expression for the total number of miles she drove in the two weeks. It can be calculate by adding distance force 2 weeks. So,

d = 291 + n

Hence, this is the required solution.

find the sum of 301+73+27 , mentally, using the associative property of addition. Show how you can use the property to group two of the addends. Explain how you found the sum.

Answers

Answer:

401

Step-by-step explanation:

301 + 73 + 27

Using the correct order of operations, you would start by adding 301 to 73. Then you'd add 27 to that sum.

Using the associative property of addition, you change the grouping to add 73 and 27 first since that equals 100, and it's easy to add 100 to 301 mentally.

301 + 73 + 27 =

= 301 + (73 + 27)

= 301 + 100

= 410

Kai sells a small magazine full of celebrity gossip to college students for $2.65 per copy. Hiring the printing press for one day, the only fixed cost, is $435 an issue. The variable cost of printing each issue is $0.82 per copy. The printer tells Kai the cost of hiring the press is to increase by $116 per day. If changing to color increases variable costs by $0.40, what is the percentage decrease in contribution margin resulting from the switch to color?

Answers

Answer:

Percentage decrease= 21.86%

Step-by-step explanation:

Giving the following information:

Selling price per unit= $2.65

Current variable cost= $0.82

Increase in variable cost= $0.4

To calculate the unitary contribution margin, we need to use the following formula:

Unitary contribution margin= selling price - unitary variable cost

Unitary contribution margin= 2.65 - 0.82

Unitary contribution margin= $1.83

New contribution margin= 2.65 - 1.22

New contribution margin= $1.43

Finally, the percentage decrease:

Percentage decrease= [1 - (1.43/1.83)]*100

Percentage decrease= 21.86%

Triangle FGH is rotated and then dilated by a scale factor of n to form triangle F’G’H’.

If FGH F’G’H’ what is the value of n

Answers

Answer:

B. [tex] n = \frac{1}{3} [/tex]

Step-by-step explanation:

If ∆FGH ~ ∆F'G'H', then their corresponding side lengths would be proportional. This means:

F'G'/FG = G'H'/GH = F'H'/FH = n

The ratio of any of their corresponding side lengths will give you the value of n.

Therefore:

n = F'G'/FG

F'G' = 5

FG = 15

Thus,

[tex] n = \frac{5}{15} [/tex]

[tex] n = \frac{1}{3} [/tex]

The scale factor which is a fraction implies that the size of ∆FGH was reduced after dilation.

Answers

Answer:

6/16

Step-by-step explanation:

Write them out bb wwwwwwww gggggg

there are 16 in total so it would be 6/16 because of each color like bb ww gg thats 6 out of 16

The probability of getting 2 socks of the same color is 1/3.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

In the drawer,

Number of blue socks = 2

Number of white socks = 8

Number of gray socks = 6

Total number of socks  = 2 + 8 + 6 = 16

The Total ways to select 2 socks form 16 socks is 120.

The Total ways to select 2 socks of the same color is

T = Possible ways of (2 blue + 2 white +2 gray) socks = 40

The probability of getting 2 socks of the same color is

Answer:

y = 3x + 2

Step-by-step explanation:

y=mx+b is slope intercept form

to find slope (m):

y2-y1/x2-x1 = 11-8/3-2 = 3

your slope is 3 so 3x

to find the y-intercept (b):

plug in y and x from either of the two points

(2,8)... 8=3(2)+b and solve for b which equals 2

so final equation is y=3x+2

Mae ling earns a weekly salary of 400 plus a 6.5 commission on sales at a gift shop how much would she make in a work week if she sold 4300 worth of merchandise

Answers

Answer:

Mae Ling will make $679.5 in a week if she sells 4300 worth of merchandise.

Step-by-step explanation:

Given that

Weekly salary of Mae Ling = $400

Commission rate = 6.5%

Mae ling's total weekly earning will be her salary plus her commission on the sales she does in the week.

Given that her sales for the said week are: $4300

Her commission will be:

[tex]Commission = 6.5\%\ of\ sales\\ = 0.065*4300\\=\$279.5[/tex]

Now to calculate her total salary, we will add the weekly salary and commission.

[tex]Total\ weekly\ Earning = Weekly\ Salary +\ Commission\\= \$400+\$279.5\\=\$679.5[/tex]

Mae Ling will make $679.5 in a week if she sells 4300 worth of merchandise.
