When animals die, the heart stops pumping blood in the body. Immediately after the heart stops beating, the body rapidly cools down until it reaches room temperature. Without the heart pumping, blood coagulates in the veins, arteries and .....

Do you see the sun shining in the night? Obviously, NO. Nights are cooler than day because you don't have the sun shining down and heat everything. The sun is the source of heat and light energy for our planet. At day time, the heat from .....

This problem is related to trigonometry. Here, change sin2Ain to cos A by formula sin2A=1-cos2A. OPen bracket and solve. You will get cosA value.  Fro cosA get sinA . Then use .....

Colors are the result of radiations reflection. So basically, if a shirt is black that means most of the radiation (sun radiation that is hitting it) is being absorbed by it and not reflected (think of a black hole for example, and why they are .....

To understand, it's better to remember that biodegradable means what decomposes/degrades/ becomes of lesser value naturally. For eg, Dog poop decomposes in the soil with the help of ants, bacteria and what not. On the other hand, plastic is .....

Water boils at 1000C. After that it starts to turn into vapour. If a water is boiled, the pressure .....

Electrical wires are made up of copper which is a metal, metals conduct heat and electricity.  When metal is cooled in the winter, the atoms receive less or no energy from the sun this makes them go back to a more stable state and thus .....

2) The "best" age for the Earth is based on the time required for the lead isotopes in four very old lead ores (galena) to have evolved from the composition of lead at the time the Solar System formed, as recorded in the Canyon Diablo iron .....

We know, When we can't simplify a number to remove a square root (or cube root etc) then it is a surd. Now try the question to remove root. Is it possible? I think you get idea .....

This problem is related to simplification of algebric expression. Here, we must start from the last expression. Factorise the last expression by using a2-b2=(a+b)(a-b). Take LCM of last 2 expression. Simplify them. Again repeat this process .....

-In general, metals are shiny materials.

Some metalloids such as Silicon (Si) have metallic luster in appearance.

-Metals have a higher value for density and melting point.

They are good heat and electricity .....

Yes, it returns back to the ground after reaching a certain height.  It can not escape out from the gravitational field of the earth.  If you want to make it going out of the earth's gravitational field,  you have to project it .....

Hewe, we need to convert radian in to degree and grade. 1)  in to degree,  We know, 1c = (180/π)0       Therfore,  π/3c  =π/3 x 180/π 0           Now .....

AB, BC and AC are different lines. They are connected to each other,  And forms a enclosed shape having 3 sides. So a triangle is an enclosed shape having 3 .....

It is due to angular momentum. Angular momentum is simply the name we give for the fact that things tend to rotate. The Earth formed out of a nebula that collapsed. As the nebula collapsed it began rotating, which may seem odd, but actually not .....

If the lift falls with an acceleration equal to the acceleration due to gravity (i.e. 9.8 m/s2),  its motion will be equal as the earth's gravity tends to make it fall with.  It will be in a freefall at this condition.  The .....

It is because, we and everything around us move together with the earth.  The atmosphere is also rotating at the same speed as the earth.  That is why, if we hover constantly in the atmosphere with a helicoptor, then also we will be .....
