All THINGS are opposite and वह EK dusre PE chipak sakta HAI

well the answer is 400 this is how Explanation:here we SEE that 1 STEP,= 10 cm hence 10 step=100 cm =1 m =TOTAL height. (h)mass=40kg g=10 hencepe=mgh = 40×10×1=400

m = 40 kgg=9.8h = 10 ×0.01Explanation:you can CALCULATE the POTENTIAL ENERGY which comes out to 3.92J

es retain the complete PHYSICAL and chemical PROPERTIES of that matter. MOLECULES are in the state of continuous motion. Moleculespossess kinetic energy. If the intermolecular spaces between the molecules DECREASES then the intermolecular force increases.

esult for State 3 uses of air pressure in daily life Syringes are used to take BLOOD for blood tests. The pressure of the liquid (blood) forces the liquid to MOVE into the syringe when its plunger is withdrawn. When air is sucked out of a drinking STRAW, the air pressure inside if DECREASES and the atmospheric pressure outside forces the liquid to go inside the straw

if the speed of the OBJECT is constantly INCREASING ALONG with distance then it is called uniform accelerationExplanation:plz follow me nd mark me as BRAINLIST

distance of object from mirror=distance of IMAGE from mirrorso distance between object and image=distance of object from mirror+distance of image from mirror=2 x distance of object from mirror=2 x (3+0.4)m=2 x (3.4)m=6.8 mExplanation:Hope you are SATISFIED with the ANSWERIF so please follow........

A spacesuit protects astronauts from those EXTREME temperatures. SPACESUITS also supply astronauts with OXYGEN to breathe while they are in the vacuum of space. They contain WATER to drink during spacewalks. They protect astronauts from being injured from impacts of small bits of space DUST.

11.2 N/m^2Explanation: Pressure= thrust/ area = 268N/ 24m SQUARE = 11.2 N/ m^2

a) LINES in ATOMIC SPECTRA

is this संस्कृति EXPLANATION: i does not KNOW SORRY

Stokes LINES are of LONGER wavelength than that of the exciting radiation responsible for the fluorescence or RAMAN effect. Anti-Stokes lines are FOUND in fluorescence and in Raman spectra when the atoms or molecules of the material are already in an excited state (as when at high TEMPERATURE).

Explain about evolution of Earth :The Earth was formed at the same time as the rest of the solar system by the coming together of materials that were not incorporated into the sun. The Earth was very hot (perhaps molten) at first, but quickly cooled off. Oceans appeared very early and have been on the surface continuously ever since. Life in the form of single-celled algae was present when the Earth was 3.5 billion years old. Animals with hard skeletons and shells appeared and formed fossils 540 million years ago. The period since then is usually broken up into the Paleozoic Era (“old life”) from 540 to 225 million years ago, the Mesozoic Era (“middle life”) from 225 million to 65 million years ago, and the Cenozoic Era (“modern life”) from 65 million years ago to the present. Dinosaurs flourished in the Mesozoic, whereas human beings have been present for only a few million years.Name of the layer      Depth of the layer               CHARACTERS#1. Crust                     approximately 5-70 km       The crust of the Earth is                composed of a great variety of IGNEOUS, metamorphic, and sedimentary rocks. The crust is underlain by the mantle. The upper part of the mantle is composed MOSTLY of peridotite, a rock denser than rocks common in the overlying crust.#2. Mantle                   about 410 kilometers            The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's DENSE, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) THICK, and makes up a whopping 84% of Earth's total volume.#3.Core                          about 2,900 kilometers.      Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).#4. Inner Core.            about 2,900 kilometers         The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).Correct the following sentences :These are all corrected sentences :1. There are *4 layers* in the interior of the Earth .2. The mantle mostly consists of *silicon rocks* .3. The outer layer of the Earth is call *Crust* .4. Most scientists believe the Earth began from around *4.5 billion years ago* .5. Outer core ( Core ) exists at the depth form  2,200 kilometers (1,367 miles)  to 2900 kilometers .Hope this was helpful !

The statements (i), (ii) and (iii) are correct.(i) TOTAL number of orbitals in a shell with principal quantum number 'n' is n 2 .Thus, for n=1, the number of orbitals =1 2 =1. It INCLUDES 1s orbital.For n=2, the number of orbitals =2 2 =4. It includes 2s, 2p x , 2p y and 2p z orbitals.For n=3, the number of orbitals =3 2 =9. It includes 3s, 3p x , 3p y , 3p z d xy ,d xz ,d yz , d x 2 −y 2 and d Z 2 orbitals.

is the total AMOUNT of matter in a substance.WEIGHT is the force acting on matter.A person has a MASS of 70kg. His weight is mass x gravity= 700 N. The person's weight will change of they go to the moon

The value of l varies from 0 to n−1. Thus its more value is n−1. Thus in this CASE, the MAXIMUM value =4−1=3

ans will be TRUE....Explanation:hope it may HELPS you......plzz MARK me as BRAINLIEST...THANKS

Principal quantum number GIVES an idea about the ENERGY and distance of electron from the nucleus . Angular momentum quantum number REPRESENTS the angular momentum of an electron and shape of subshell. Magnetic quantum number tells about the number of ORBITALS and their orientation.Spin quantum number indicates the direction of SPINNING of an electron

Explanation:Sliding friction is the force RESISTING the motion when a body slides on a surface. The force of friction DEPENDS on the AREA of contact between the TWO surfaces. As the area of contact is less in the case of rolling than in the case of sliding, rolling friction is less than the sliding friction.

Current = 9.09AExplanation:The current drawn by the electric oven can be CALCULATED using the formula➡ P = V × I➡ I = P/VSubstituting the values, we get➡ I = 2000 W/220 V = 9.09 ATHE current drawn by the electric oven is 9.09 A which EXCEEDS the safe limit of the circuit. This causes the fuse to MELT and BREAK the circuit.

Unlike-poles ATTRACT: When a north pole and south pole point together, the arrows point in the SAME DIRECTION so the FIELD LINES can join up and the magnets pull together (attract).

Good morning dear friend.Explanation:SORRY! I can't answer as I am in a pressure. Very sorry for that. Thanks for FREE points.Blessings of peace and GRACE, be with you today and everyday.Stay Healthy! Stay BLESSED!Do meditation!

Atomic Nucleus: Explanation:The identity of an element can be determined by the number of protons found it its nucleus. The NEUTRONS may VARY and are KNOWN as isotopes; the electrons may be different, which we IDENTIFY as ionic counterparts of elements.
