I am not against shots let me first state this, I have other children that have all their shots. Also I am going to school to become a nurse and I have received my immunization. The problem is my youngest has alot of different minor health concerns and because of this I do not want this child to have their shots. There is also a family history of complication due to shots. The problem I am having is that when I took my child to the doctors they refused to give me a medical exemption. (which by state law I have the right to request)
I live in the state of Illinois and you are supose to be able to get a medical exemption from your doctor so I am wanting to know if there is anyone out there that has had this problem and if so what did you do?

wow, I did not think so many people would
try to dissect the components.

forget, in this case, that the vehicle is
a train.

let's move the weight to the water and
make it a freight cargo ship.

the ship has a diesel engine, it also
has photo electric cells plastered all over it
and it has 6 monster sails.

ugly as sin ship. ok.

with just the sails, the ship will SAIL along
at 2 kilometers an hour in speed.

if we remove the sails and just have
the photo electric power, the ship will
travel at 4 kilometers per hour in speed.

if we remove the photo electric cells and
instead, install diesel engines, we can
travel 16 kilometers per hour speed.

in some situations in power, it is a good
idea to combine power resources.

the question then, is, if we were to combine
all 3; diesel engines, and
add the photo electric cells and
add the sails, would the ship only go
16 kilometers per hour speed--or would it go faster with the other two sources also working
concurrently?

Keeping in mind that a large amount of H2SO4 has leaked into a freshwater environment (pond) harbouring plant and animal life. The result must ideally be a Precipitation Reaction.

Thanks Everyone

Use the rules of differentiation to find the derivatives of the following function. Simplify terms wherever possible, but it is not necessary to factorise and then cancel any of the expressions.

x^2 + y^2= 4

x^2 + y =4

2x + 3y= 4

y^2=x^2 - 1

im not really sure how 2 do these i know that for every input of x that y can only have 1 output but im still not sure.. plz help

The front wheels of a tractor are 0.5 m in diameter and the rear wheels are 2 m in diameter.

whats the distance travelled by the tractor when the front wheel has revolved 2100 times more than the rear wheels ?

(1)8.8 km
(2)2.2 km
(3)5.28 km
(4)4.4 km


KINDLY ,PLEASE dont give soln, i want to solve myself, i want to take the challenge ....if i cant solve it , i will post it again ....but for the time being i need hints .

what i dont understand is , whats the relationship between front wheel and rear wheel ? i think the tractor will move the same distance .......whether the front wheel is bigger or smaller than the rear wheel ...it does not matter .

BY the way , as per the question , it asks how much distance tractor will move given a front wheel and real wheel revolution difference .

can you give me some HINTS so that i can use that in my head and proceed to solve ?

thank you

When you all of a sudden shudder from a chill that is not caused by a draft or any other environmental means. A lot of times it causing goose bumps. People will commonly tell me that this is caused by a ghost or goose walking on my grave. Is this an unexplained phenomenon or is there a real medical reason for this?

i read from somewhere reliable that lightspeed is considered the fastest speed and you cant exceed it . i think its said by einstein or smething.

why is it so ? just becos currently it appears to be the fastest speed?

i read on some websites and they say the moon is highly possible that its hollow on the inside due to the size and gravity strength on moon.

i also read that the moon is just at the right size and distance from earth that it completely block off the sun during solar eclispe.

religion aside.

could moon be form by aliens and stuff ? or issit just sheeeeeeer luck that it is form this way ?

i also read that a side of the moon is completely dark when facing earth , is it true ?

i also read that neil armstrong claim he saw alien and stuff and was warned .. lol ?
