foam cup refers to styrofoam cup. So it is opaque.

it is called thermoCol in some countries. The packing material that

comes in tv boxes.

There is nothing to change no color change so it is a physical change

Heat is transferred in three ways. Conduction, convection & Radiation.

kettle of water conducts heat by direct contact with heat. This is by the process called conduction. Hot water will rise up as it is less denser than the cold water which is heavier, and it helps in heating the entire water in the kettle.

q = mc T

it is a straight question.

Formula for density = Mass / Volume

use the data guven, D = 49.01/ 4.5 gm/ mL = 10.891111 gm/cc

Note 1mL = 1cc.

The golden temple is made of bricks.Later Marble was used to make designs in the roof and on the walls.The upper part of golden temple is gold plated.

Rubber, like many other polymers has a "glass transition temperature" below which it will shatter just like glass.

Polypropylene for example should not be used for temperatures not too far below freezing point.

So the answer to your question is "It all depends".

The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them

Remember :

Force = kg * m*s^-2

Momentum = kg * m* s^-1

The difference is force involves acceleration,; the difference in speec(velocity) over a given timr.

Momentum involves speed (velocity) only. NOT a change in velocity.

So your van of 1200 kg with a speed pf 25 ms^-2

The momentum is = 1200 kg & 25 ms^-2 = 30,000 kg m s^-1

The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.

It's the Greek word ΥΠΟΘΕΣΙΣ.

ΥΠΟ- = Sub- . -ΘΕΣΙΣ = Position, standpoint.

Hypothesis = Grounds lain, supposition, presupposition, presumption, infrastructure.

In Greek, (ΘΕΜΑ) stands also for: case, cause, matter, affair.

Being a knight around 600 years ago meant a number of different things. A Knight owed his loyalty to the local lord but he usually received land because of that. Knights existed because lords needed to get protection from other lords and other kingdoms that were imposing upon them. knights have been romanticized by Hollywood in recent years. The truth is that most Knights were only one step above a peasants and usually died in battle fighting a never ending war of power struggle between lords, kings or clergy.

If you are meaning why are there hills, mountains, and valleys, then the answer to your question is: wind and water.

The sun heats water, and it evaporates into the atmosphere. This water then falls back to the ground in the form of rain. When it rains at any elevation above sea level, the water then flows from high elevation down to sea level. The water then groups together and forms rivers which cut the ground and wash loose dirt down the river along with it.

In areas where there is no water( the desert) the wind is the primary erosion factor. The wind picks up small particles of sand and hurls it through the air and smacks it into rock, which breaks off minuscule particles.

These two factors are the main causes of erosion, which in turn is what causes topography.

Yes, Hydra is Multicellular.

Because invertebrates are animals without backbones, they differ from vertebrates.

They are to digest when eaten.

Invertebrates are important because they start the food chain e.g amphopods eat algae under the arctic ice cap and they get eaten by a vertebrate that gets eaten by a larger vertebrate.... and so on. So invertebrates basically power most food chains.

The 10 most poisonous creatures are: 1- Box Jellyfish 2- King Cobra 3- Marbled Cone Snail4- Blue-Ringed Octopus 5- Death Stalker Scorpion 6- Stonefish 7- The Brazilian wandering spider 8- Inland Taipan 9- Poison Dart Frog 10- Puffer Fish

No, they have endoskeletons like any other bird (and you, too).
