Please answer and show how you solved this:

A physics student wishes to deterine the amount of electric energy consumed in one day at his school as a result of classroom and hallway lighting. A quick survey revealed that there were approximately 200 40W fluorescent lights operating under a potential difference of 240V for 16 hours each day.

I’m not sure, but i’m guessing we need to find out how much in the timespan of 24 hours because thats what the kid wants to find out?

I am allergic to fluorescent light. This has been diagnosed by my MD. Obviously this makes shopping a more difficult task and I have not been able to work for about 3 years. As we become more energy savvy and incandescent lighting will ultimately become a thing of the past, I worry. Has anyone ever heard of this or does anyone know someone who suffers from the same [odd] ailment?

thnx for the help

“I’m not crazy,” I tried to force myself to believe that statement briefly before continuing, “I’m just a little unwell.” I wondered how dumb I sounded. It was the first thing any of us had said, and it was just lyrics from a song.
The fluorescent lights caught every imperfection and made it public, opened you up to criticism and judgment. Somehow it shined in a way to force me into what felt like a spot light, I was forced onto a stage with an audience consisting of an elder couple stealing glances and sweet touches when a spark lite up their wrinkled eyes, a balding man in overalls bent over his plate shoveling food into the black hole where his mouth should have been placed, a group of young girls giggling because they were out past curfew, a creepy man who despite my current state, let his eyes roll over my body, studying harder than he ever had in school, and the two men sat across from me in our booth.
They nodded. They knew I was unwell. They knew I was probably crazy. Here they sat despite the facts, which would have repelled any normal human being. When someone yells rape people run away, it is normal for people to run from disaster when they can, if it is not yours, you run. Who needs more disaster? These two didn’t run, they stopped. I could have, no I should have questioned them about said topic but I was having a little problem coming up with anything other than song lyrics.
“I’m sick of all the insincere.” I stated, rather insecurely if I may say so, “So I’m gonna give all my secrets away.” They nodded; I finished “This time, don’t need another perfect line.”
I felt numb, cold and wet, bruised and weak. I could detach myself from my head, I could just tell them, what’s the worst that could happen?
They must have noticed the conflict on my face because the younger of the two gave me what I assume was meant to be a reassuring smile, it looked more like pity. The older one slowly reached his hand across the table; it headed straight towards me, a simple touch.
The flashbacks begun and struck with such force I was flung back against the poorly cushioned booth. The pictures flew at me from all angles, like sharp, rusted daggers yearning to sink into my scarred skin and twist until I gave in to them.
They seemed to tease me, barely breaking skin, before they shot through me like my hollow body was paper thin; it was effortless. The pain was delayed, I felt a high. I was untouchable, indestructible. The warmness spread through me without notice, the daggers were still going, right through my core. I was seeping, a red liquid oozed out and flooded the restaurant. There was so much, it was everywhere, all around me. I was suffocated by my own blood; I fought to reach the top where the air was still clean. It was heavy though, definitely not water, too thick to fight. I gave in.
I gasped, what I believed to be my last breath, it was easier than I thought though, too easy for a dying breath. I blinked and looked around. The lights no longer showed everything, in fact now they were hiding things. They hid the flood, for it could no longer be seen. The eyes of my audience grew bigger as all of them snapped to me. None of them showed the drastic scene that just played out. People run.
I focused on the only eyes I really cared about, the two pairs that showed worry and stress. Those eyes are the only ones that believed that I was in fact dying; suffocating on my own blood.

This is really really raw, I have this idea but I can’t seem to figure out how I want to start it.
Sorry, I know it’s kind of long.

I’ve been having these really scary health problems for at least the past 5 years of my life. It’s really been about the past 8, but it’s gotten really bad in the past 5. I really think I have a brain tumor. All of my problems seem so neurological, and my cognitive functioning has deteriorated too quickly compared to where I used to be for it to be anything else.

To keep it short as possible, when I was about 14 years old, I noticed that I couldn’t taste my food anymore a lot of the time (sometimes my ability to taste would return, but it was never really the same). Then when I was 17, I started having these dizzy spells all of the time. I mentioned it to my parents a few times but downplayed it and didn’t say I wanted to go to a doctor because I was scared. Then over the next several years, things just got progressively worse. I started having these really bad, piercing headaches on the right side of my head near my ear that are there pretty much 24/7. My memory keeps getting worse and worse…I start doing things and then forget I’m doing them all of the time, and when I was in college, I had to study 4x as long as other people to commit the concepts to memory for an exam. My coordination is all messed up…I was never the type of person to have issues with coordination, and it took me three tries to pass the test for my driver’s license, and I still have issues with parking. My balance is messed up…I feel like I’m going to fall over all of the time. I can’t concentrate on anything…I feel like I’m never fully present anywhere I go because I can’t fully focus on anything, and my mind is always trailing off somewhere else. I have dizzy spells and chest pain randomly all of the time. Flashing lights and fluorescent lights make me feel like I’m going to lose consciousness. The list goes on.

I’m scared to apply to jobs because of my random dizzy spells all of the time and because I don’t think I’d be good at any of them since I have so much trouble concentrating, remembering things, and thinking straight now. I’m afraid to go in public because of the random dizzy spells all of the time. I can’t date because there’s no point if I’m dying. I have an online friend who introduced me to some online jobs that are really designed for stay-at-home moms, and I’ve been doing them to try and save up money so I can move out and get away from my dad who tells me I’m retarded like 8 times a day, but they don’t pay very well, so it’s taking forever. I don’t know what to do with myself. I’m not welcome here. I stay in my room and try to go out to go to the bathroom or to get food when my dad isn’t home because he always yells at me and insults me if he sees me. Earlier I thought he was sleeping, so I went to the kitchen to make a sandwich, and he came downstairs and started yelling at me that I was retarded and stupid and couldn’t do anything right. I can’t make myself not exist. I have to be somewhere. I guess I could go live on the streets, though.

I just don’t know what to do. There’s all this stuff I want to do, but I’m confined to my bed pretty much because of the stupid dizzy spells, and when I do get up, I feel like I’m drifting through the world not really able to concentrate on anything. I’m not suicidal, but I do wish I could acquire a new brain and get out of this house. I’m terrified to go to a doctor even if I could go, and there’s really no point since, after 8 years of all of this, a brain tumor will be pretty much incurable.

The light fixture in my bathroom has 3 fluorescent light bulbs. One of them was not on so I had to replace it. I turned off the switch and immediately started unscrewing the bulb. With every twist, the bulb would light up and turn off when it stopped. I imagine it has to do with static electricity but I didn’t think it could be enough to fully light up the bulb…….either that or my house will burn down right?

I am going to be starting a Dubia Roach breeding tank soon, maybe two.
I am going to keep a set of 50 in a 10gallon aquarium, and another set of 50 in a 10gallon (maybe slightly larger) Tupperware box.

The cages will both be spot cleaned every day and entirely cleaned out every four months.

Is this an okay habitat and breeding ground for Dubia Roaches? Let me know if there is anything wrong with it or whether it is okay.

I notice that, under fluorescent lighting, my face looks slightly red and blotchy. I have really good skin, and it looks fine in normal lighting, but under fluorescence it’s just too blotchy. I don’t wear foundation or concealer, because I don’t need it (unless I’m under fluorescent lighting). I really don’t want to start either.

Are there any natural ways to get rid of redness before school in the morning, or the night before?
If there aren’t, then I would love some recommendations for foundation or concealer.

I have combination skin, and an olive skin tone. Any recommendations would be great!

Thanks!

I have a page for science due monday and the last question is why does a incandescente lightbulb get hotter then a fluorescent light tube?
Please help?!?!

so i have a baby albino pacman frog.hes been into aestivation sbout 3 times.ive now been using fluorescent lighting. Pacman frogss are supposed to eat things that move in their path. but mine dosnt he just buries himself and doesnt eat nything . just when im not there his crickets “dissapear” he doesnt have any discharges or any unhealthy signs. but ihe avoids water so i put him in the water dish. his skin is perfect but i dont know whats wrong. he also has whit stuff around his eyes with blak lines ant the middle. are those his eyelids?

I have recently been diagnosed with Lupus and Fibromyalgia. I am very photosensitive to the point that I cannot sit in the doctors office under the fluorescent lights without having a flare. I feel sick all of the time and I am extremely tired. What would be the chances of me receiving disability? I am 42 years old and I have been working since I was 17 years old. I have an Associates degree in Accounting and have been at the same job since 1995.
By the way I forgot to mention that I am allergic to steroids which is the main treatment for Lupus. Also I have migraines. So I have Lupus fog, migraine fog and fibro fog. I have a hard time concentrating and have been making many mistakes that has cost my employer lots of money over the last couple of years. Fortunately my employer (my mother) has been very kind but it has become very hard for her to take care of my clients and her clients too.

I am allergic to fluorescent light. This has been diagnosed by my MD. Obviously this makes shopping a more difficult task and I have not been able to work for about 3 years.

Hello. I am doing a science project that involves testing the growth of Black Seeded Simpson Lettuce (Lactuca Sativa) plants. The bulbs are a constant variable in the experiment. I am pretty sure that fluorescent lights bulbs are cheap and good bulbs to enhance the growth rate of plants; if not, please correct me. Do you know a specific light bulb item/brand (from Home Depot, Lowe’s, Amazon, etc.) that would be best for this experiment? Thanks!
My budget is under roughly $25, but if necessary, I will do what I must.

I keep hearing this, yet can’t find it anywhere online. There are not even 7 anymore. There is a list of like 7 different lists of 7. So there is really like 49 or so. Yet I still can’t find it anywhere.

Is this true? Or is this just another thing like Filipinos created fluorescent lights, M-16s, Karaoke, cure for AIDS, and the Space Shuttle?

Almost all bar lights that I’ve seen (3′ + tall) are fitted into these housings that cover half of the light. They require that both ends be plugged into the housing. Are there fluorescent bar lights that plug in only one end, so that the other end is free and I don’t have an ugly housing blocking half of the light? (I’m building a pedestal light, with the fluorescent lght pointing straight up. A light that plugs into the ground will have 360 degree illuminance; I hope you see what I’m getting at) Any ideas on what these are called? And what store (online or physical) sells these? Thanks so much!

I only have one bonsai plant, so I don’t need a room lit up with grow lights.
I have recently learned that a 40 watt fluorescent light bulb screwed into a desk lamp (or any lamp for that matter) gives an indoor bonsai plant suffcient light to stay healthy. I would appreciate hearing from anyone who has successfully kept bonsai plants healthy under fluorescent light bulbs?
I would also like to know if it’s safe to put 40 watt fluorescent bulb into a regular lamp?
