The correct answer is Albert Einstein.

• Relativity is a theorem, formulated by Albert Einstein, which states that space and time are relative and all the motion must be relative to a frame of reference.
  • It is a notion that states, laws of physics are the same everywhere. This theory is simple but hard to understand.
  • It states
    • There is no absolute reference frame, if the object or momentum is only in relation to other objects, then velocity can be measured.
    • The speed of light is constant irrespective of who measures it or how fast the person measuring it, is moving.
• Albert Einstein's Theory of Relativity encompasses two theories, namely special relativity theory and general relatively Theory.
  • Special Theory of Relativity:
    • Einstein first introduced this term in the year 1905. It is a theorem that deals with the structure of space-time. Einstein explained this theory based on two postulates.
    • The laws of physics are the same for all irrespective of the velocity of the observer.
    • The speed of light is always constant regardless of the motion of the light source or the motion of the observer.
  • General Theory of Relativity:
    • General relativity theory developed by Einstein in the year 1907-1915 states that being at rest in the gravitational field and accelerating is identical physically.
    • For example, an observer can see the ball the same way on the rocket and on Earth. This is due to the acceleration of the rocket, which is equal to 9.8 m/s². This theory relates to Newton's gravitational theory and special relativity.
    • Gravitational Time dilation: Gravity influences the passage of time. Clocks in the deeper gravitational wells run slower than in general gravitational levels.
    • Light rays will bend in the gravitational field.
    • The universe is expanding, and parts of it are moving away from Earth faster than the speed of light.

• Archimedes: Archimedes discovered the Archimedes principle that states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces.
• Charles Darwin:  Darwins proposed the theory of evolution by natural selection. first formulated in Darwin's book "On the Origin of Species" in 1859, is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.
• Sir Isaac Newton:  Sir Isaac Newton was born on 25 December 1642 and is believed to be the greatest and most influential scientist who ever lived.
  • Newton was an English physicist, mathematician, astronomer, and theologian who worked on many practical experiments and laid the foundation for the principles of classical mechanics.
  • It was in 1687 that his first edition of his Philosophiae Naturalis Principia Mathematica (later translated in 1825 as The Mathematical Principles of Natural Philosophy ) was published.

(ii) Each appliance has a separate switch to ON/OFF the flow of current through it. 

(iii) In each circuit different appliances can be connected across the live wire and the neutral wire. 

(iv) Fuse connected to avoid damage

Parallel axis theorem: Parallel axis theorem states that the moment of inertia of a body about any axis is equal to the sum of its moment of inertia about a parallel axis through its center of mass and the product of the mass of the body and the square of the perpendicular distance between the two axes.

If I_C is the moment of inertia of the body of mass M about an axis passing through the center of mass, then the moment of inertia I about a parallel axis at a distance d from it is given by the relation, I = I_C + Md²

1. Given Data: M = 500 g = 0.5 kg. R = 10 cm = 10 × 10^-2 m 

Moment of inertia of disc about diameter = Id = \(\frac{1}{4}\) MR² 

Id =\(\frac{1}{4}\) × 0.5 × 0.1 kg m² = 0.0125 kg m² 

2. Apply a parallel axes theorem, moment of inertia of the disc about a tangent to the disc and parallel to the diameter of the disc

= \(\frac{1}{4}\) MR² + MR² = \(\frac{5}{4}\) MR² = × 0.5 × 1 

= 0.0625 kgm²

3. Moment of inertia of the disc about an axis passing through the centre of disc and perpendicular to the plane of the disc

= \(\frac{1}{2}\) MR² = \(\frac{1}{2}\) × 0.5 × 0.1 = 0.025 kgm²

Sky waves: Long distance communication can be achieved by ionospheric reflection of radiowaves back towards the earth. Sky wave propagation and is used by short waves broadcast services. The ionosphere is so called because of the presence of a large number of ions of charged particles. It extends from a height of ~ 65 km to about 400 km above.

Space wave: A space wave travels in a straight line from transmitting antenna to the receiving antenna.Space waves are used for line-of-right (LOS) communication as well as satellite communication. At frequencies above 40 MHz, communication is essentially limited to line-of-sight paths. At these frequencies,the antennas are relatively smaller and can be placed at heights of many wavelengths about the ground.

The peltier effect is a temperature difference created by applying a voltage between two electrodes connected to a sample of semiconductor material. The phenomenon can be useful when it is necessary to transfer heat from one medium to another on a small scale.

Routable protocols can work with a router and can be used to build large networks. Non-Routable protocols are designed to work on small, local networks and cannot be used with a router.

It provides a framework for discussing network operations and design.

One of two sublayers of the data link layer of OSI reference model, as defined by the IEEE 802 standard. This sublayer is responsible for maintaining the link between computers when they are sending data across the physical network connection.

It is a collection of programs that enables user to create and maintain a database. In other words it is general-purpose software that provides the users with the processes of defining, constructing and manipulating the database for various applications.

Virtual channel is normally a connection from one source to one destination, although multicast connections are also permitted. The other name for virtual channel is virtual circuit.

Bauxite, mica

Along any transmission path from a given source to a given destination, a group of virtual circuits can be grouped together into what is called path.

Packet filter is a standard router equipped with some extra functionality. The extra functionality allows every incoming or outgoing packet to be inspected. Packets meeting some criterion are forwarded normally. Those that fail the test are dropped.

The average atmospheric pressure at the sea level is 1013.25 mb

Earth is called Living Planet because it is the home of various forms of life.

A database is a logically coherent collection of data with some inherent meaning, representing some aspect of real world and which is designed, built and populated with data for a specific purpose.

One of the main causes of congestion is that traffic is often busy. If hosts could be made to transmit at a uniform rate, congestion would be less common. Another open loop method to help manage congestion is forcing the packet to be transmitted at a more predictable rate. This is called traffic shaping.

It is a sequence of IP addresses identifying the route a datagram must follow. A source route may optionally be included in an IP datagram header.

Sending a message to a group is called multicasting, and its routing algorithm is called multicast routing.

a) Dengue 

b) Dengue virus

When hierarchical routing is used, the routers are divided into what we will call regions, with each router knowing all the details about how to route packets to destinations within its own region, but knowing nothing about the internal structure of other regions.

It is a problem that can ruin TCP performance. This problem occurs when data are passed to the sending TCP entity in large blocks, but an interactive application on the receiving side reads 1 byte at a time.

High fiver with shivering and profuse sweating are the major symptoms of malaria. Other symptoms include headache, vomiting, diarrhoea, anaemia etc.

We know that the principal value branch of cos^–1x & sec^–1x is [0, π].

Now, sec^–1(–1) = sec^–1(secπ)   (\(\because\) secπ \(=\frac{1}{\cos\pi}=\frac{1}{-1}=-1\))

= π

\(\therefore\) The principal value of sec^–1(–1) is π.
