This is a short answer type question as classified in NCERT Exemplar

Consider a fig in which m is mass of sphere and R is the radius having h height above the floor

The sphere will roll without slipping when w=v/r where v is linear velocity and w is angular velocity .

By conservation of momentum

mv (h-R)=Iw=2/5mR2 (v/R)

mv (h-R)=2/5mvR

h-R=2/5R

so h = 7/5R .d i  sphere will roll here so no loss of energy.

Torque = F (h-R)

For torque=0 h=R sphere will have only translational motion. It would lose energy by friction.

b i v

the sphere will spin clockwise when t>0 so h>R

so c i i and a i i i

(i) When moving down the periodic table within a group, ionization enthalpy generally decreases due to increased atomic radius. However, in the case of gallium (Ga) and aluminum (Al), gallium experiences a higher effective nuclear charge due to less shielding from its inner electrons, resulting in a higher ionization enthalpy compared to aluminum.

 

(ii) As boron is smaller in size and the sum of its first three ionization enthalpies i.e. ΔH1+ΔH2+ΔH3 is very large so boron does not allow to lose its all three valence electrons and exist as

This is a short answer type question as classified in NCERT Exemplar

Moment of force τ 1= F (a)….anticlockwise

Moment of weight mg τ 2=mg (a/2)……. (clockwise)

Cube will not exhibit motion then τ 1 = τ 2

F × a = m g × a 2

F=mg/2

Cube will rotate when τ 1 > τ 2

F × a > m g × a 2

F>mg/2

At a/3 from point A then

mg × a 3 = F × a o r F = m g 3

when F=mg/4 which is less then mg/3 there will be no motion.

The following reaction takes place in the test tube

 

  1. i) When Aluminium is treated with dilute hydrochloric acid.

Al + HCl  -à AlCl3

ii) When Aluminium is treated with dilute sodium hydroxide solution.

Al  +  NaOH -àNaAlO2 + H2

 

In both the cases, the Hydrogen atoms are evolved. So, when a burning match stick is brought near the test tube we hear a pop sound.

Aluminium does not react with concentrated nitric acid. A "layer" of "Aluminium Oxide" is formed, when aluminium reacts with the nitric acid because "nitric acid" is an oxidising

BCl3+3H2O→B (OH)3+3HCl

B (OH)3+2H2O→ [B (OH)4]+H3O+

 B (OH)due to its incomplete octet accepts an electron pair (OH)-  to give has configucation [B (OH)4].

Boron in this ion involves one 2s orbital and three 2p orbitals. Thus, hybridization of B in [B (OH)4] is sp3

AlCl3 + 6H2O  [Al (H2O)6]3+ +3Cl-

Hence, hybridization of Al is sp3d2

As compared to carbon, silicon is bigger in size and is less electronegative. It shows resistance in forming p−p multiple bonding which is easily done by carbon. Thus, SiO2 is a 3−D network where each silicon is linked covalently to 4 oxygen atoms while in CO2, Carbon is linked with two oxygen atoms with double bond in a linear manner.
