In an earthen pot, water gets evaporated quickly through the pores. Cooling is caused by evaporation. Some heat energy is utilised during the process of evaporation. Since this energy is taken from the water itself, it leads to a lowering of temperature in the remaining amount of water.

X³ - 3x² - 9x - 5
= x³ + x² - 4x² - 4x - 5x - 5
= x²( x + 1) - 4x ( x + 1) - 5(x + 1)
= (x + 1)(x² - 4x - 5)
= (x + 1)(x² -5x + x - 5)
= (x + 1)(x - 5) (x + 1)
hence, (x +1), (x -5) and (x +1) are the factors of given polynomial .
OR
x3 - 3x2 - 9x - 5
Let p(x) = x3 - 3x2 - 9x - 5
By trial, we find that
p(- 1) = (- 1)3 - 3(- 1)2- 9(- 1) -5
= - 1 - 3 + 9 - 5 = 0
∴ By Factor Theorem, x - (- 1), i.e., (x + 1) is a factor of p(x).
Now,
x3 - 3x2 - 9x - 5
= x2(x + 1) - 4x(x + 1) - 5(x + 1)
= (x + 1)(x2- 4x - 5)
= (x + 1)(x2 - 5x + x - 5)
= (x+ 1){x(x - 5) + 1 (x - 5)}
= (x + 1)(x - 5)(x + 1).

Density of water varies with temperature. It is highest at 4 oC. At low tempreature, When ice is formed, density is reduced. So At low temprature in ocean, A layer of Ice floats on water and below this layer, all aquatic species can survive. At high temeperature, Warm water of ocean causes vast currents which circulate heat from equator to temperate zone. Hence, play role in controlling climate of whole earth.

Light: Light is a form of energy which helps us in seeing objects. When light falls on an object, some of the light gets reflected. The reflected light comes to our eyes and we are able to see an object.

A body is said to be at rest if it does not change its position with respect to a fixed point in its surroundings. If the body changes its position with respect to a fixed point in its surroundings, then body is said to be in motion.

Newton gave three laws of motion that describe the motion of bodies. These laws are known as Newton's Laws of motion.
The first law of motion is stated as: An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.
Newton's first law of motion gives us a definition of force. It says that Force is something that changes or tends to change the state of rest or uniform motion of a body.
The second law of motion states that: The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.
Newton's third law of motion states that: Whenever a body exerts a force on another body, the second body exerts an equal and opposite force on the first body

a = p*(1 + r/100)^n
a = 7865, p = 6500, n = 2 & r = ?
a/p = (1+r/100)^n
(a/p)^(1/2)=(1+r/100)
[(a/p)^(1/2)]-1=r/100
100*{[(a/p)^(1/2)]-1} = r
100*{[(7865/6500)^(1/2)]-1}=r=10%

If You mean this one Denominator so let's explore what the numerator and the denominator represent in a fraction. ... For example, in the fraction 5/9, the numerator is 5 and the denominator is 9, so the fraction 5/9 means 5 parts of a whole object, which is divided into 9 parts of equal size.......That's It, Or if you're talking about anything else, then sorry but I don't know......
