B.R. Ambedkar was a prominent leader who fought for the rights of untouchables and played a crucial role in drafting the Indian Constitution.

Vladimir Lenin was a key figure in the Russian Revolution of 1917, leading the Bolshevik Party to power.

Mahatma Gandhi was the key leader associated with the Civil Disobedience Movement, which started in 1930.

The organism level of organization is the highest, as it encompasses all systems and structures functioning together as a single living entity.

CN- is a strong field ligand and causes a large splitting of d-orbitals, leading to low-spin complexes.

CN- is a strong field ligand that causes a large splitting of d-orbitals, leading to low-spin complexes.

Parallel lines have the same slope. The slope of the given line is 3/4, and the line 6x - 8y + 10 = 0 also has the same slope.

The slope of the given line is 4/5. A line parallel to it must have the same slope, hence y = (4/5)x - 3.

The slope of the given line is 3. The slope of a line perpendicular to it is -1/3.

'Furthermore' is a linking word that indicates addition to a previous statement.

Water has a higher boiling point due to strong hydrogen bonding.

Mercury has a very high surface tension due to strong cohesive forces between its molecules, higher than that of water, ethanol, and benzene.

Mercury has the highest surface tension due to strong cohesive forces.

Glycerol is a thick liquid and has a higher viscosity compared to the others.

Benzene has a lower boiling point compared to water, ethanol, and hexane.

Benzene is a non-polar liquid, while the others are polar.

Hexane is a non-polar solvent, while the others are polar.

Ethanol can form strong hydrogen bonds due to the presence of an -OH group.

Ethanol has a lower surface tension compared to water and mercury due to its molecular structure.

Since 0.01 is 10^-2, log_10(0.01) = -2.

Using the property of logarithms that states log_a(b) - log_a(c) = log_a(b/c), we find log_2(8) - log_2(4) = log_2(8/4) = log_2(2).

Since 81 is 3^4, log_3(81) equals 4.

Logarithm of zero is undefined, hence log_5(0) is the correct answer.

The last identity is incorrect; it should be log_a(b) + log_a(c) = log_a(bc).

The Power Rule states that log_a(b^c) = c * log_a(b).

The International Date Line is at 180°, so the closest longitude is 180°.

Polaroid film is specifically designed to polarize light by allowing only light waves oscillating in a certain direction to pass through.

Rubber is an insulator and has a much higher resistivity compared to metals like copper, aluminum, and silver.

Sound travels fastest in solids; hence, the speed of sound in steel is higher than in air, water, or wood.

Steel has the highest tensile strength among the given materials.
