Question

4 more to go lol Hallelujah!! @agent0smith

Answer 1

The highest frequency of a radio station is 107.9 Mega Hertz. What is the wavelength?
2.8 m
2.2 m
2780000 m
28 m
I don't have the speed to calculate it...???

Answer 2

speed of light is 3*10^8

mega means million

Answer 3

So...
3*10^8/107.9?

Answer 4

MEGA

107.9 Mega Hertz = 107.9*10^6

Answer 5

OH MY FCKN GEE

Answer 6

2780000 m?

Answer 7

OH MEGA FCKN GEE

w/e 3*10^8/(107.9*10^6) is

Answer 8

OMFG don't be like my actual physics teacher lol.

Answer 9

2.8?

Answer 10

yep

well what is he like :P

Answer 11

He has a pony tail lol and stomps his leg when he asks a question. And then tries to solve problems and when he messes up he goes.. "Oh man! Forgot to do this n that." LIKE OMG DID THEY NOT TEACH YOU THAT? LOL

Answer 12

The frequency of a C note of sound is around 240 Hz. If the speed of sound in air is 340 m/s, what is the wavelength of the sound wave, in meters?

Answer 13

No pony tail. No leg stomping. I sometimes forget things, like all teachers, but not often.

Same formula again :P

Answer 14

Hahha lol n kk. so...
speed=F X WAVELENGTH?

Answer 15

YES

Answer 16

1.417?

Answer 17

I gotta round to 3 decimal places

Answer 18

Looks fine.

Answer 19

The frequency of a radio wave is 95.5 x 107 Hz. What is the wavelength of the wave, in meters?
Answer to 3 sig figs.
Can I just plug that into the calculator lol

Answer 20

Yes, speed is 3*10^8

Answer 21

Ok so I'm doing...
95.5*10^7/3*10^8
Is that right?

Answer 22

no
speed = freq*wavelength

Answer 23

I'd still be dividing wouldn't I? To get wavelength by itself.. I gotta divide by frequency on both.. same thing as speed/freq=wavelength right??

Answer 24

Yes

Answer 25

Wow I feel sucha smartas hahha

Answer 26

I have 3.141. right?

Answer 27

Looks good. Smartass.

Answer 28

I never got a diagram to go with this question. But it's asking to look at the diagram. Weird...
Look at the diagram. Assume all resistors are 4.0 ohms. What is the total resistance?

Answer 29

Hahha lol ikr

Answer 30

would it be like 1/4+1/4+1/4?

Answer 31

It also could be 8. Or 16. Or who knows.

Answer 32

Hahha stop lol.

Answer 33

And these are the options for that question. (Last one I posted)
2.8 ohms
3.1 ohms
4.1 ohms
5.6 ohms
none of these

Answer 34

Just guess

Answer 35

what would you put down lol

Answer 36

lol it would be a guess with no pic

Answer 37

Hahha lol kk
