Yogita Ingle 6 years ago

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.

NEWTON THIRD LAW OF MOTION =TO EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION.

Yogita Ingle 6 years ago

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

Yogita Ingle 6 years ago

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......
