Objectswith tightly packed molecules are denser andsink.Objectswith more loosely packed molecules are less dense andfloat. Whether anobject sinks or floatsdepends on its density. ... Others have molecules that are packed more loosely. This is density.

This question seems quite easy.An input device is one which we use to give inputSome input devices are mouse, keyboard, joystick, track pad, mike

answer of this question ismouse

Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror.

The characteristics of an image formed in a plane mirror:

image formed is virtual ie image cannot be projected or focused on a screen

the distance of the image ‘behind’ the mirror is the same as the distance of the object in front of the mirror

the size of the image formed is the same as the size of the object

the image is laterally inverted ie left-right reversal of the orientation of the image, not top-down vertical reversal eg PHYSICS becomes SCISYHP

altitude/orientation is always upright.

Yes you can seperate Chalk and water. To do so use the filtration method. As Chalk and water is an unsolvable mixture, you can seperate it by filtering the suspension through filter paper. just pour the mixture of insoluble solid and liquid into a beaker through filter paper.

Definitionofelectromagnetic wave. : one of thewavesthat are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radiowaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Electromagnetic radiation, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a wave, and has anoscillatingelectric field component and anoscillating magneticfield. These waves oscillate perpendicularly to and in phase with one another.

. Dyeing is the application of dyes or pigments on textile materials such as fibers, yarns, and fabrics with the objective of achieving color with desired fastness.

alumminium is highly receive bcoz of presence of valence electronbut after removal its valence electron i.e Al^3 become stable i. e gain stable noble gas configuration due to stable it does not react with another ones

alumminiun is highly receive bcoz of presence of valence electtonvut after removal it's valence electrons become stable gain stable Noble gas configuration due to stable it does not react with another ones

because Al is reactive because

it requires electrons so it

reacts quickly

but Al3 is already came to

noble configuration.

unless given any charge at large scale

Al is not nutral it has to gain more Al ions to get stable

because Al³ has already completed no. of electrons in its outer most shell

Two methods of producing magnetic fields are as follows: (a) Magnetic field can be produced by placing a permanent magnet or a horse-shoe magnet at the place, where magnetic field is required. (b) Magnetic field is produced around a current carryingstraightconductor or a current carrying coil.

Asoiland water do not mix with each other,oilingforms a protective coating for the metal and hencepreventit fromrusting.Oilcan penetrate the oxide-water on the metal and stabilize it.A thin layer ofgreasewillprevent rustor oxidation of iron based products.

that's right

no , because microorganisms helps in decomposition of organic matter and convert it into nutrients that are essential for soil.

a = dv/dt

a = (dv/ds)(ds/dt)

a = v (dv/ds)

∫ a ds = ∫ v dv

as = ½ v² + constant

v = u at s = 0

a * 0 = ½ u² + constant

constant = -½ u²

as = ½ v² - ½ u²

2as = v² - u²v²=u²+2as

The material which has electrical conductivity between that of a conductor and that of an insulator.Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.

answer is th main source of our food like almonds, fruits breads,potato etc.

Plants are thesources of foodingredients like grains, cereals, vegetablesandfruits. Animalsprovideus with milk, meat productsandeggs. Cows, goatsandbuffaloes are some common animals whichgiveus milk. Milkandmilk products like butter, cream, cheeseandcurd are used all over the world.

The additional foods are important because they: Provide nutrients that may not be available in the staple food. For example, legumes such as peas, beans and lentils add protein, iron and other minerals and fat; green and yellow vegetables and fruits add vitamins A and C, folate, and fibre.

Animal-basedfoodsare themain sourcesof complete proteinandinclude meat, fish, poultry, eggs, milkandcheese. Plant-basedfoodsalso contain protein, but are "incomplete"sourcesof protein, meaning they contain only some of the essential amino acids.

Animal based foods are the main sources of complete protein and include meat fish egg milk and cheese. plant based foods also contain protein but are "incomplete" sources of food meaning they contain only some of the and essential animo acids

Surface water is water on the surface of the planet such as in a river, lake, wetland, or ocean. It can be contrasted with groundwater and atmospheric water. Non-saline surface water uses is replenished by precipitation and by recruitment from ground-water.

Ground water is used in surface water

Ininsulatorsthe electrons in the valencebandare separated by a largegapfrom the conductionband, inconductorslike metals the valencebandoverlaps the conductionband, and insemiconductorsthere is a small enoughgapbetween the valence and conductionbandsthat thermal or other excitations can bridge thegap

Theweightof an object is theforceof gravity on the object and may be defined as themasstimes the acceleration of gravity, w = mg.

Since theweightis aforce, its SI unit is the newton. Densityis mass/volume.

Weight is a force

weight is a force,is the answer

Yes, Weight is a force.

SI Unit of force is NEWTON.

so simple we can say that weight is force which SI unit is Newton ,F=W=mg

An oxide is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2–atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.

Eachgeneoccupies a specific position on a chromosome. Becausegenesprovide instructions for making proteins, and proteins determine the structure andfunctionof each cell in the body, it follows thatgenesare responsible for all the characteristics you inherit.

Please mention the question.

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.
