2) what is the smallest thing in the world ever discovered
3)what is theta tan theta
4)what are the what is mean by displacement reaction give example
5)what is the double displacement reaction give example
6)define exthermic and endothermic reaction
​

Answer 1

Answer:

not fair this much big only some i will answer

4)The unit circle definition is tan(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side.

3) qurak is the smallest thing ever discovered

TOP 10 STRONGEST :

• DIAMOND
• STONE
• IRON
• STAINLESS STEEL
• BRICK
• CEMENT
• PLASTER OF PARIS
• POLYCARBONATE
• THERMOPLASTIC
• WOOD

The smallest thing ever discovered in the world is an atom .

$\tan(x) = \frac{ \sin(x) }{ \cos(x) }$

When one element displaces other element from its salt solution is known as displacement reaction .

Example : CuSO4 + Fe ---> FeSO4 + Cu

When in a reaction the elements change there place to form different compounds is called a double diaplacement reaction .

Example : CuSO4 + H2S ---> H2SO4 + CuS

Exothermic :

• A reaction in which a energy is released in the form of heat or light is called exothermic reaction .

Endothermic :

• A reaction in which heat is absorbed during the reaction in the form of electricity , heat or light is called endothermic reaction ...
