has the thirst got anything to do with the losing sweat? i was thinking that maybe the decrease in body volume in sweating stimulates the production of aldosterone and hence produces thirst...but i'm not sure though!

simplify both questions
1) 8 + square root of 28 over 2

2) square root of 7 (9 square root of 5 minus 3 square root of 7)

In other words, a message of words could be desolved in a special liquid. To discover what the message is, you drink it. The liquid makes its way to your brain which turns the liquid into speech that you hear inside you. What do you think of this?

1) A clerk moves a box of cans down an aisle by pulling on a rope attached to the box. The clerk pulls with a force of 188 N at an angle of 25.0° with the horizontal. The box has a mass of 36.9 kg, and the coefficient of kinetic friction between box and floor is 0.450. Find the acceleration of the box.

2)A box of books weighing 259 N is shoved across the floor by a force of 435 N exerted downward at an angle of 35° below the horizontal.

(a) If µk between the box and the floor is 0.57, how long does it take to move the box 9 m, starting from rest? (If the box will not move, enter 0.)

(b) If µk between the box and the floor is 0.75, how long does it take to move the box 7 m, starting from rest? (If the box will not move, enter 0.)

--what do the symbols even mean.... so yeah im really lost if u guys could explain how to do these probs so i know in the future, i'd appreciate it a lot. thanks

"When Hillary bought the next bag of food she did so just in time.Her normally petite lizard started an amazing growth spurt eating 1.5 times as the previous day. How long will this new bag last?"
I found there are 182 pellets a bag and she was eating 6 pellets every day pre growth spurt. I got 8 days by a table but need a sequence formula and I'm not quite sure of the common ratio. Thanks in advance.

Think about it! Think ouside the Bible, gain a little insight! I'm sure you heard there's possibly another planet like earth that supposely has an identical twin of you, "the original you". Their DNA gave them the chance to clone themselves which is where you come in. When everyone reached a certain age with intelligence, we were deposited on this earth. The rest, as they say, is history! Our government doesn't want scientists to start cloning. Why? Are they afraid we'd do what our identical selves did many eons ago?
What do you think?

I'm pretty sure that women bleed at every 28 days, which is about the same time taken by the moon to go around the Earth once. Why does that happen? Is it only a coincidence or there is some inter-influence going on?
