• Malabar Exercise was started as Indo-US bilateral naval war drill in 1992.
• Japan had formally joined the exercise as permanent participant in 2015, making it trilateral exercise.

• A concave lens is a lens that possesses at least one surface that curves inwards.
• It is a diverging lens, meaning that it spreads out light rays that have been refracted through it.
•  A concave lens is thinner at its centre than at its edges and produces an erect and diminishing image.

• Impulse is defined as the integral of force over the time interval for which it acts.
• If a moving object is stopped by an impact, the change in momentum of the object occurs. This change in momentum is called the impulse.
• Impulse is a vector quantity and the impulse force on the body is measured in terms of its impulse force.

The momentum of a body, P = mv, where m is the mass of the particle, and v is the velocity of the particle.

Momentum is directly proportional to velocity.

The kinetic energy of a particle is given by the equation, KE = (1/2)mv^2.

KE = (1/2)mv²

When the momentum of a body is doubled, then the velocity will be doubled.

⇒ KE = (1/2) × m × (2v)² = 4 × (1/2)mv²

Hence, If the momentum of a body is doubled, the kinetic energy becomes 4 times.

To find the Power in this case, we must apply the following formula:

P= F_net . v

We first need to find out the net force applied on the car.

F_net = mass × acceleration + resistive force

       = 300 × 4/3 + 100

       = 400 + 100 = 500 N

Now, P= 500 × 10 = 5000 W = 5 kW

• The magnetic force acts perpendicular to the direction of motion of the proton, thus it does not change the speed but only its direction of motion
• This in turn means the velocity and momentum of the particle is changed.

A body is said to be in uniform motion if it travels equal distances in equal intervals of time. A body is said to have non-uniform motion if it travels unequal distances in equal intervals of time. These concepts are based on Newton’s three laws of motion.

• Conduction is the transfer of heat energy by direct contact.
• Convection is the movement of heat by actual motion of matter.
• Absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase, liquid or solid material.
• Advection is defined as the transfer of heat or matter by the flow of a fluid, especially horizontally in the atmosphere.

Hence, 4 is the correct option.

A scalar quantity is a one-dimensional quantity consisting of only magnitude and devoid of direction.

• Work is an example of scalar quantity as it has no precise direction attached to it making it a one-dimensional quantity.
• Other examples of scalar quantities include time, volume, speed, mass, temperature, distance, entropy, energy etc.

The residual volume is volume of air left inside the lungs after exhalation, this is the minimum volume of the lungs that remains even after air is pushed out of the lungs.

The mucus glands are located in the lining of the nasal cavity. They secrete mucus. Mucus is a fluid that keeps the lining of the respiratory system moist and traps dust and other foreign bodies in it. It is removed by small hair structures called cilia towards the mouth.

Kala Azar, also known as Visceral Leishmaniasis is a disease caused by protozoan parasites of the Leishmania genus. It is detected by the K-39 test. Typhoid is detected by the Widal test. ELISA test is done to detect AIDS.

Night Blindness results in loss of vision in the dark and is caused by the deficiency of Vitamin A

Lichens are best indicator of pollution because lichens are very sensitive to sulphur dioxide pollution in the air. If air is very badly polluted with sulphur dioxide there may be no lichens present, just green algae may be found. If the air is clean, shrubby, hairy and leafy lichens become abundant. A few lichen species can tolerate quite high levels of pollution and are commonly found on pavements, walls and tree bark in urban areas. Lichens have also shown sensitivity to some other pollutants, such as heavy metals and other toxic gases in air. 

Bast fibre (also called phloem fibre or skin fibre) is plant fibre collected from the phloem (the "inner bark", sometimes called "skin"). In vascular plants, phloem is the living tissue that transports the soluble organic compounds made during photosynthesis in particular sugar sucrose, to parts of the plant where needed.
