What is mass energy equivalence and significance

Answer» MASS-energy equivalence states that mass is concentrated energy. In his theory of SPECIAL relativity Einstein FORMULATED the equation E=mc^2. There is a tremendous amount of energy in mass. A 20g MARBLE contains as much energy as a 500 kiloton hydrogen bomb, but this energy is very difficult to release

Why do we use convex surface for side view mirror

Answer» CONVEX mirrors are commonly used as rear-VIEW (wing) mirrors in vehicles because they give an erect, virtual, full size diminished image of distant objects with a wider field of view. THUS, convex mirrors enable the driver to view much LARGER area than would be POSSIBLE with a plane mirror.

Calculate the refractive index of a liquid with respect to air applying Snell's law (Use Geometric construction) Answer is 1.19Show all the steps​

Answer»

tion:This was a question in our school prelim PAPER too. ICSE 10th. In air you will SEE that they have not provided the angle of incidence you have to find itAngle of Incidence = 90 - 30 degree = 60 degrees why?because the normal  is perpendicular to plane.Now they have given the angle of refraction = 45 degrees Snell's LAW states that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.therefore, μ = sin60 = sin45 = On solving you will get, = 1.19 approx.

if an electric iron of 1200W is used for 30 minutes everyday,find the electric energy consumed in the month of april??​

Answer»

c energy produced in the MONTH of April is 18 kWhExplanation:Given,P = 1200 W = 1.2 kW      Use TIME per day = 30 minutes = 1 / 2 hrsWe know,No. of DAYS in April = 30 daysTotal time IRON being usedT = 1 / 2 * 30 = 15 hrsWe know,Energy consumed = PtSubstituting the VALUE of P and T= 1.2 kW * 15 hr= 18 kWh    Hence,Electric energy produced in the month of April is 18 kWh

How to do electron configuration

Answer»

1Find your atom's ATOMIC number. Each atom has a specific number of electrons associated with it. 2Memorize the basic list of orbitals. As an atom gains electrons, they fill different orbitals sets according to a specific order. Each set of orbitals, when full, contains an even number of electrons. The ORBITAL sets are:    The s orbital set (any number in the electron configuration followed by an "s") contains a single orbital, and by Pauli's Exclusion Principle, a single orbital can hold a maximum of 2 electrons, so each s orbital set can hold 2 electrons.    The p orbital set contains 3 orbitals, and thus can hold a total of 6 electrons.    The d orbital set contains 5 orbitals, so it can hold 10 electrons.    The f orbital set contains 7 orbitals, so it can hold 14 electrons.    The g, h, i and k orbital sets are theoretical. No known atoms have electrons in any of these orbitals. The g set has 9 orbitals, so it could theoretically contain 18 electrons. The h set would have 11 orbitals and a maximum of 22 electrons, the i set would have 13 orbitals and a maximum of 26 electrons, and the k set would have 15 orbitals and a maximum of 30 electrons.    Remember the order of the letters with this mnemonic:[1]Sober Physicists Don't Find Giraffes Hiding In Kitchens.3Understand electron configuration notation. Electron configurations are written so as to clearly display the number of electrons in the atom as well as the number of electrons in each orbital. Each orbital is written in sequence, with the number of electrons in each orbital written in superscript to the right of the orbital name. The FINAL electron configuration is a single string of orbital names and superscripts.4Memorize the order of the orbitals. Note that orbital sets are numbered by electron shell, but ordered in terms of energy. For INSTANCE, a filled 4s2 is lower energy (or less potentially volatile) than a partially-filled or filled 3d10, so the 4s shell is listed first. Once you know the order of orbitals, you can simply fill them according to the number of electrons in the atom. The order for filling orbitals is as follows: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s.5Fill in the orbitals according to the number of electrons in your atom. For instance, if we want to write an electron configuration for an uncharged calcium atom, we'll begin by finding its atomic number on the periodic table. Its atomic number is 20, so we'll write a configuration for an atom with 20 electrons according to the order above.    Fill up orbitals according to the order above until you reach 20 total electrons. The 1s orbital gets 2 electrons, the 2s gets 2, the 2p gets 6, the 3s gets 2, the 3p gets 6, and the 4s gets 2 (2 + 2 + 6 +2 +6 + 2 = 20.) Thus, the electron configuration for calcium is: 1s2 2s2 2p6 3s2 3p6 4s2.    Note: Energy level changes as you go up. For example, when you are about to go up to the 4th energy level, it becomes 4s first, then 3d. After the 4th energy level, you'll move onto the 5th where it follows the order once again (5s, then 4d). This only happens after the 3rd energy level.6Use the periodic table as a visual shortcut. You may have already noticed that the shape of the periodic table corresponds to the order of orbital sets in electron configurations. For example, atoms in the second column from the left always end in "s2", atoms at the far right of the skinny middle portion always end in "d10," etc. Use the periodic table as a visual guide to write configurations – the order that you add electrons to orbitals corresponds to your position in the table.If this answer is helpful, please mark it as the brainliest:)Explanation:

A farmer moves through a square field of side 10m in 40s m . What will be the magnitude of displacement of the farmer at the end of 2 min 20 sec

Answer»

istance covered 10m in 40secTotal time taken= 2MIN 20SEC= 140secTotal round completed = 140/40=3.5 roundsSo If an object MOVES from A to D, the shortest PATH will be from A to C. So displacement is AC, that we will FIND by phythogoras theorem.AC2= AB2 +BC2 AC2= (10)2 +(10)2AC2= 100+100AC2=200AC = (200)1/2
