I recently shattered my IPhone 6 screen and the next day took it to the mall to get it fixed. I paid $145 at a store in my mall who apparently specializes in fixing screens. When I went to pick my phone up I realized a small blue (dot) light at the top of my phone a little to the right above the camera. I asked the man what it was and he just said it was a sensor but wouldn't really specify for what.. My boyfriend is freaking out saying its some sort of monitor or something and the Apple Store cant tell me anything since I took the phone to a 3rd party place. Does anyone know what this might be??? Could it be some sketchy tracker or some sort?

I know this problem isn't that hard, Im just over thinking it. If someone could just tell me what formula to use or even better, explain how to work out the problem that would be great!!

The starter of a race stands at one end of a line of runners. what is the difference in time between the arrival of the sound of his pistol at the nearst runner and at the most distant runner 10m farther away? (in a sprint, 0.01s can mean the difference between winning and coming in second)

(my teacher provides the answers for us to check our work so the answer should come out to be 0.029s)

My boyfriend and I were having sex and he was wearing a condom when he came. After he came he took the condom off and kept ******* me without a condom on. He wiped his dick off before getting inside me again and pulled out before coming the second time. Is there a chance I could get pregnant if there was any left over sperm on his penis?

side note: (I come from a VERY fertile family- all my relatives and mother have gotten pregnant on their first try...)

I already know what your thinking... yes I did the Kyle Jenner lip challenge and YES I do regret it!!! Unfortunately it left a big ring of purple around my lips (bruise) and I was wondering if anyone had an idea as to how long this will take to go away / if there is anything I can do to speed of the healing process... it is very unnatractive- looks like I ate a purple popsicle in the dark with my hands tied lol..

PLEASE HELP!!

How would you prepare 260. mL of 0.360 M NaCl solution using an available 1.75 M solution?

Dilute _________ mL of a 1.75 M solution to a final volume of 260. mL.

How much water must be added to 532 mL of 0.197 M HCl to produce a 0.130 M solution? (Assume that the volumes are additive.)

Ive been working at this and keep getting it wrong: PLEASE help!!!!

When aqueous solutions of lead(II) ion are treated with potassium chromate solution, a bright yellow precipitate of lead(II) chromate, PbCrO4, forms. How many grams of lead chromate form when a 1.30-g sample of Pb(NO3)2 is added to 15.0 mL of 1.03 M K2CrO4 solution?

Can someone show me how to do this and solve it? Should I first balance the equation or?

For the following unbalanced equation, indicate how many moles of the second reactant would be required to react exactly with 0.125 mol of the first reactant. State clearly the mole ratio used for the conversion

Cl2(g) + KI(aq) → I2(s) + KCl(aq)

____ mol Cl2 ✕ ( ____ mol KI / ____ mol Cl2 ) = ____ mol KI

THANKYOU

3 H2SO4(aq) + 2 Fe(s) → Fe2(SO4)3(aq) + 3 H2(g)

Fe2(SO4)3 ____ mol

H2 ____ mol

N2H4(l) + O2(g) → N2(g) + 2 H2O(g)

N2 ____ g

H2O ____ g

PLEASE help!!! I've been staying home sick from school and need to see an example solved for how to do this!!!!

CO2(g) + 4 H2(g) → CH4(g) + 2 H2O(l)

CH4 _____ mol

H2O _____ mol

Mono has been going around my area recently and alot of people have it. Theres been alot of parties in the last couple weeks and Ive kissed a few different guys. My throat is sore and very swollen, i have a headache, and im exausted. it could be from sharing a drink with someone a longer time ago but about 2.5 weeks ago was when i would have gotten it through kissing for the first time in the past month. is it possible this is mono or is it too early to tell / something else? (im a 16 year old girl btw)

I recently bought a 2012 Jeep Patriot and I love everything besides the manual door locks. I have to push down the lock on each and every door and the key to unlock my car only unlocks the drivers door. Is there any type of gadget or ANYTHING I can buy or have done to have a master lock that will lock/unlock all the doors at once? Im so afraid someone or myself will forget to lock their door!!!

My male puppy got neutered on Friday (today is sunday) so two days ago and up until now everything has been looking fine. I just checked his sutures and it looks like theres a little bit of bleeding. Its only on one part but im not sure what to do at this point. How do I know if he ripped a stitch or something? I don't think its infected... yet. My mom said she doesn't think its a big deal and told me to put Neosporin on it? should I do that?? Please help!

I will be going to college in a couple years and I have a strong idea about starting a small organization/rescue for dogs. I have loved dogs my entire life and want nothing more than to show neglected dogs what love is like. I want to rescue dogs off the streets and from death row at shelters.

Would studying something like business be beneficial for this? Im guessing a job like this is more of a side job since it will rely on a lot of donations so im going to need another job to help me get by as well. Does anyone know how I should go about this? Just looking for ideas/info/tips! thanks!

my 3 month, 3 pound yorkie puppy just are a hibiscus flower. Aren't these toxic to dogs? what should I do please help!!!!!
