I) Define atomic mass unit.ii) What is the numerical value of mole. iii) Name the elements present in oxide ion. |
|
Answer» Answer: 1)An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of any isotope of any element is expressed in relation to the carbon-12 standard. For EXAMPLE, one atom of helium-4 has a mass of 4.0026 amu. 2)One mole contains exactly 6.022 140 76 x 1023 elementary entities. This number is the fixed numerical VALUE of the Avogadro CONSTANT, NA, when expressed in the unit mol–1 and is called the Avogadro number. 3)An oxide (/ˈɒksaɪd/) 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– (molecular) ion. Metal oxides thus typically CONTAIN an anion of oxygen in the oxidation state of −2. hope it helps please mark me as brainliest |

An object of mass 10 kg is made to fall freely from a height 20 m. Let us denote the starting point as A. The object strikes the ground with a velocity 'v' in 2 s. (Take g= 10 m/s2 in all parts )(i) Find the potential energy of the object after 0.5 s. |
|
Answer» Answer mass, m = 1kg height, s = 20m initial velocity of ball, U = 0m/s acceleration, a = 10m/s 2
Using, v 2 = u 2 + 2as = 0 + 2×10 ×20 = 400 v = 20m/s Now, LET us take upward direction as POSITIVE and downward direction as negative. Initial momentum of the ball (before striking the ground) = m×v = 1×(-20) (velocity is downward, hence negative) = -20kgm/s Now, when the ball strikes and rebounds, its velocity becomes +20m/s (after striking, it moves upward, hence positive velocity) Final momentum (after striking the ground) = m×v = 1×(+20) = +20kgm/s Change in momentum = Final momentum - Initial momentum = 20kgm/s - (-20kgm/s) = 40kgm/s in upward direction. |
