Everything works great except the wind chill reading has been off 81 degrees from the day I set it up. It reads 101 when it should be 20. Is the wind chill converted by the unit itself or is it part of the information transmitted by the MSN Direct Signal.

The equation h = -16t^2 + 112t

This gives the hieght of an arrow, shot upward from the ground with an intial velocity of 112 ft/s , where t is the time after the arrow leaves the ground. I have to find the time it takes for the arrow to reach a hieght of 120 ft ??

Please help !

If two people, one in the middle of the sahara desert and the other in the middle of the north pole, were to have the same amount of fire wood + a small fire of exactly the same size, which one would burn for the longest?

My reasoning being, Heat, being part of the triangle of fire, would only be present in the desert enviroment....but do you think that would play a part?

When ever we have family over like 5 more people weird stuff happens. Me and my brothers and my dad were sitting on the couch. All of a sudden these 2 flower holders with a mirror in the middle on the wall fell off. The flower handles fell at the same time. The mirror was just sitting there on the wall. No body was even near both sides of the wall either. And my sister in law keeps seeing a face out the window. So does my mom and aunt. They say its my dead grandma. So do you think my house is haunted. And what should i do to try and capture some evidence.

The captaian has an order to go from base A to port B
in shortest possible route. He sets the ship course to NW
and leaves the base. When en route, another order arrives
redirecting the ship to port C. The captain turns the ship
90 degrees to the left. After some time a fire abroad the ship
interrups her voyage. The captian makes emergency
turn 130 degrees to the left and proceeds back to the base A.
The ships retuns to her base from the west and enters repair
dock. What is the area of the sea enclosed in the loop?

Sub-Micro Hitec servo PC board (HS-56HB rated at 4.8-6v), with 4.8v input to 3 pole servo motor from a slightly bigger servo and pot-meter from an X-Mods RC vehicle. Soldered all and works to some degree with a TX and RX but very very sensitive and jitters like mad! When the TX is turned off and the RX is on the servo stops jittering but rests to one extreme. I tried the pot from the micro servo and a bit less sensitive but still jitters off the charts! I also tried to swap the two power poles on the motor oposite but the servo then just moved to one extreme. I also tried a few different caps and resistors I had from 540 size motor rebuilding but either no help or same as no power. I'm stumped. Thanks for any help!!

This question has been haunting me since childhood. I don't expect u people to give the correct answer or explanation to me but still let me see.

From our school studies we have studied that this universe came as a result of the 'big bang' of a dense spherical ball. Before that something might have happened and i don't care about that. What i want to know is that when did all these physical activities start taking place. There was no one no god or someone who said " Go! the time starts now" and suddenly everything came into existence. No. But there must have been some kind of start. Did u get to the depth of my question?? Plz give scientific explanations.

I wonder i have never found anybody wondering about this puzzle. But may be some Einstein has already given an explanation to this. If so plz let me know.
