Planck's constant has the dimensions [ML²T⁻¹], exactly those of angular momentum. From E = hf, h = E / f. Energy has dimensions [ML²T⁻²] and frequency has [T⁻¹], so h has [ML²T⁻²] ÷ [T⁻¹] = [ML²T⁻¹], with the SI unit joule-second.

Soft sand gives way slowly, so the person is brought to rest over a longer time and the force on the body is smaller.

A Mach number greater than 1 means the body is moving faster than sound in the surrounding medium. The Mach number is the ratio of a body's speed to the speed of sound in the medium around it, named after the Austrian physicist Ernst Mach.

The Mariana Trench lies in the western Pacific, east of the Mariana Islands and near Guam. It is the deepest known part of the world's oceans.

An object denser than the liquid sinks, and one less dense than the liquid floats. By Archimedes' principle, a body placed in a liquid feels an upward buoyant force equal to the weight of the liquid it displaces.

Milk is a colloid in which tiny droplets of fat are dispersed in water, so it is not uniform at the microscopic level and counts as a heterogeneous mixture.

The apple's gravitational potential energy first becomes kinetic energy as it falls, some is lost as heat to the air on the way, and at impact the rest goes into heating the ground and apple and into sound.

Diamond and graphite are allotropes of the same element, carbon, so their chemical properties are the same; only their physical properties differ.

Jaipal Singh Munda campaigned for a separate state of Jharkhand for the tribal people of Chotanagpur, not for Chhattisgarh. Jaipal Singh, a Munda from Ranchi district, studied at Oxford and won an Oxford Blue in hockey.

In the electrolytic refining of copper, a solution of copper sulphate made acidic with a little dilute sulphuric acid carries the copper ions between the electrodes.

The Constitution does the opposite: Article 18 abolishes titles, so receiving a title is not a Fundamental Right. Article 18 forbids the State from conferring any title other than a military or academic distinction, and bars citizens from accepting a title from a foreign State.

Two ammonium ions, each with a charge of +1, are needed to balance one carbonate ion with a charge of -2.

Putting a soft iron bar inside a solenoid makes the magnetic field much stronger, so the claim that the field stays the same is not correct.

It is a warm current that flows south along the east coast of Australia, carrying tropical water from the Coral Sea.

Magnesium combines with oxygen to form a new substance, magnesium oxide, so a chemical reaction takes place. When a magnesium ribbon is heated, it burns with a dazzling white flame and leaves a white powder: 2Mg + O₂ → 2MgO.

The Universal Declaration came in 1948, the Refugee Convention in 1951, the Covenant on Economic, Social and Cultural Rights in 1966 and the Convention on women (CEDAW) in 1979.

The nitride ion, N³⁻, carries a charge of minus three, so its valency is -3. Nitrogen has five electrons in its outer shell.

Most members of the Rajya Sabha are elected indirectly by the elected members of the State Legislative Assemblies through proportional representation by means of the single transferable vote.

A telescope's objective must gather as much light as possible from a distant object and form a large image, so it is both wide and of long focal length.

At a fixed temperature, changing the pressure of an ideal gas does not change the speed of sound in it, so x and y are equal.
