I know cos36° is (1+root 5)/4; can sin36° be expressed without any square root inside a square root?

The answer CANNOT be rounded! And please read the requirements carefully!

I know it is only a tiny ammount, because it has a tiny ammount of mass - but how can light have mass, when it travels at the speed of light?

In a geothermal heat pump system, (link: http://geoexchange.org/about/how.htm)
it indicates use of high density polyethylene.
But pipes should be able to conduct heat.. Isnt polyethylene a poor conductor of heat?? Then why are they used here??
If not, which would be the most adequate material??

I am reaching 40. The problem is that i am feeling tired almost everyday around evening. After the day's work, I am left with no energy. I believe the VItamines could be helpful. I don't want to get into so called Energy Boosters which use chemicals. I would certainly prefer Vitamines as they are naturally a part of out diet. I am basically a vegitarean.

What Vitamines I can take to back up my energy?

can someone give me estimates on this...I cant really find many sites comparing the 2 and when one should be used over the other. I figured the only reason to use a flask would be if you need to stopper it and mix. And im not sure about their percisions.

Question 2. Examine a 250 mL beaker available in your drawer. Compare the precision of these pieces
of equipment with that of a graduated cylinder, pipette and buret. What is the maximum precision that can
be achieved by using the beaker and the flask? (example: nearest 10 mL, nearest 1 mL, nearest 0.1 mL,
nearest 0.01 mL etc). When should a beaker or Erlenmeyer flask be used to measure volumes?

Can every form of energy can be converted into every other form of energy.if this statement is true then if we take sound energy then it mean it can be converted to all other forms of energy they might be light,heat and all other
if no then whats the true story?

H2SO4 + 2NaOH --> Na2SO4 + 2H20

MαVα / MβVβ = 1/2 M=molarity α=acid
2(ΜαVα) = ΜβVβ V=volume β=base

Therefore 2 mole of sulphuric acid is required to neutralise 1 mole of sodium hydroxide ??????????

Is This Logical??????
