That is how the ship has been described in the announcement of her visit to the Kenyan port, and a frigate of this class is a general purpose warship built with a reduced radar signature so that it is harder to detect at sea.

The scheme is built for meritorious children of economically weaker households, so an income test applies along with the marks test, and the parental income of an applicant must not cross that figure.

Fresh scholarships under the scheme go to Class IX students who qualify in the selection examination conducted by the respective State or Union Territory government, and one lakh such awards are made every year.

A student selected under the scheme receives that amount every year, and the money is credited straight into the student's own bank account through Direct Benefit Transfer, which removes middlemen from the payment chain.

That is where Paranur Toll Plaza stands, and it is the stretch on which Tamil Nadu received its first barrier-less tolling arrangement from the National Highways Authority of India.

Cameras at the plaza read the registration plate of every vehicle that crosses, and the FASTag-based Electronic Toll Collection system then debits the user fee from the account linked to that vehicle.

It lies on the Tambaram-Tindivanam section of NH-179B and has become the first location in Tamil Nadu where the National Highways Authority of India charges toll without a boom barrier, letting vehicles roll through while cameras and FASTag settle the fee.

An alkene carries one carbon-to-carbon double bond, and that bond uses up two hydrogen atoms that a saturated chain would have held, so the formula drops from CnH2n+2 to CnH2n. Putting n equal to 2 gives C2H4, ethene, the simplest alkene; n equal to 3 gives C3H6, propene.

Alkanes are saturated hydrocarbons in which carbon atoms are joined only by single bonds, and such a chain carries the largest possible number of hydrogen atoms, given by CnH2n+2.

Carbon is a non-metal, so it does not show metallic character; it neither loses electrons to form positive ions nor shows the lustre and malleability of metals.

An ionic compound is a lattice of positive and negative ions held by strong electrostatic attraction, and that force explains all its other properties.

A covalent bond is formed when two atoms share one or more pairs of electrons so that each completes its outermost shell.

A metal loses electrons and a non-metal gains them, so the transfer makes oppositely charged ions that attract each other, and that attraction is an ionic bond.

Sodium is a metal that gives up an electron easily and chlorine is a non-metal that accepts one, so the two form sodium chloride, an ionic compound.

Ionic compounds dissolve well in water but not in kerosene, petrol or other non-polar organic solvents, so this statement is not a property of theirs.

The element with atomic number 56 is barium, and its outermost electron enters the 6s orbital, so it sits in the s-block.

Relative atomic mass is measured against the carbon-12 atom, one-twelfth of whose mass is taken as the standard unit. That unit is the atomic mass unit, written u, and it is defined as exactly one-twelfth of the mass of one atom of carbon-12.

Melting of ice only changes the state of water from solid to liquid; no new substance is formed, so it is a physical change.

Ice melts at 0 degrees Celsius, and 0 degrees Celsius is 273 K on the Kelvin scale. To change Celsius into Kelvin, add 273 to the Celsius reading, so 0 + 273 gives 273 K; the melting point of ice is usually written as 273.15 K in exact work.

The balanced equation is 2FeSO4 → Fe2O3 + SO2 + SO3, so p = 2, q = 1, r = 1 and s = 1.
