Question

i am horrible at math can anyone help?
this is scientific notation btw

medical X-rays with a wavelength of about 10 (-10)m, can penetrate completely throughout the skin
Q- Ultraviolet rays which cause sun burns only penetrate top level of skin it has a wavelength about 1,000 times the wavelength of an X-ray, find the wavelength of ultraviolet rays. show your work

-_- im horrible at math... does anybody understand this its like I'm reading greek or something

Answer 1

dang thick chick looks like you got one hard problem on your hands

Answer 2

i know -_-
this is depressing

Answer 3

well y don't u just talk to me and take a brake

Answer 4

do you understand any of it?

Answer 5

no what i would do is not do it and ask your teacher about it tomorrow in class

Answer 6

lol i do online and the teacher is just as stupid as i am he makes us do textbook :/

Answer 7

Wavelength of X-rays = \(\large 1.0 \times 10^{-10} ~ m \)

Wavelength of Ultraviolet rays = 1000 times the wavelength of X-rays =
\(\large 1000 \times 1.0 \times 10^{-10} ~ m = 1.0 \times 10^3 \times 10^{-10} =
1.0 \times 10^{3 - 10} = \\ \large 1.0 \times 10^{-7} ~ m\)

Answer 8

and that is his problem he is making you do it out of a text book

Answer 9

omg @aum your a genius ^.^ jesus has answered my prayers (hallelujah!!)

Answer 10

lol. You are welcome.

Answer 11

lol aum is smart as hell

Answer 12

can you help with another?? @aum

Answer 13

what is it

Answer 14

I can try one more here. After that close this question and post a new one.

Answer 15

ok this is the question

the wavelengths of visible light are between 3.8 X 10 (-7)m and 7.6 X 10(-7)m
Are these wavelengths longer or shorter than those of ultraviolet rays? explain.

Answer 16

aum were u at she needs your help

Answer 17

shhhh let the genius concentrate @williamauthorlee

Answer 18

lol ok

Answer 19

i wonder how he understands it o.O
im not even a blonde and half the crap it said made me feel like i was reading a foreign language

Answer 20

that question made me feel stuid

Answer 21

Wavelength of Visible light: \(\large 3.8 \times 10^{-7} \text{ to } 7.6 \times 10^{-7} \text{ m }\)

Wavelength of Ultraviolet rays: \(\large 1.0 \times 10^{-7} \text{ m }\)

Since \(\large 1.0 \times 10^{-7} \lt 3.8 \times 10^{-7} \),

the wavelengths of Visible light is LONGER than the wavelength of Ultraviolet rays.

Answer 22

you make me feel dumb -_- how do u understand this @aum

Answer 23

Lots of practice and interest in math.

Different things come easy to different people. I can't sing or dance or play musical instruments or write poetry or paint or ...... millions of things.

Answer 24

I'm alright with math but this lesson just threw me off... big time but thanks this helped a lot

Answer 25

You are welcome.

Answer 26

dang how do u understand this

Answer 27

lol he practices and has better understanding with math than we do and I'm sure he's more advanced

Answer 28

me to

Answer 29

so thugchick do u have a email

Answer 30

lol i do but i can't log into it

Answer 31

dang y
