William Jones felt that the study Indian history, philosophy and law would not only help the British learn from Indian culture, but it would also help Indians rediscover their own heritage, and understand the lost glories of their past. This would also establish the British as guardians of Indian culture and gain total control.

d1= 45cm , d2= 30cm
Number of tiles= 3000
Rate per m²= ₹4
Area of Rhombus= 1/2×d1×d2
= (1/2) × 45 × 30=675
Area of 1 tile= 675 cm² = 675/10000 m²
Area of 3000 tiles= 3000 × (675/10000)
[1cm²= 1/10000m²]
cost of Polishing the floor
= Total Area × rate
= (3000 × 675 ×4)/10000
= 3× 675×4/10
= 3× 67.5×4
= 12× 67.5
= ₹ 810
Hence the total cost of polishing the floor = ₹ 810

• Lustre: Metals in the pure state generally shine. The shine on the metallic surface is called the metallic lustre.
• Malleability: The property of metals by which they can be beaten into thin sheets is known as malleability.
For example, silver metal is beaten to make silver foil used for decorating sweets.
• Ductility: It is one of the properties of metals by virtue of which they can be drawn into wires. For example, copper and iron can be drawn into wires.
• Conductivity: Metals are good conductor of heat and electricity. Heat and electricity can pass through them.
• Sonorous: Metals produce a ringing sound when struck hard. So, they are called sonorous.
• Solid: All metals are solid except Mercury, the only metal which is liquid at room temperate. We can cut sodium (Na) and potassium (K) metals with the help of a knife. Mercury, sodium and potassium are exceptional metals. Examples of metals: iron, copper, gold, aluminium, silver, calcium etc.

The push or pull of an object is considered a force. Push and pull come from the objects interacting with one another. Terms like stretch and squeeze can also be used to denote force.
In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity.
Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force and the application of force is the point where force is applied.
The Force can be measured using a spring balance. The SI unit of force is Newton(N).

Computer memory, a device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. In computing, memory refers to a device that is used to store information for immediate use in a computer or related computer hardware device. It typically refers to semiconductor memory, specifically metal–oxide–semiconductor (MOS) memory, where data is stored within MOS memory cells on a silicon integrated circuit chip. The term "memory" is often synonymous with the term "primary storage". Computer memory operates at a high speed, for example, random-access memory (RAM), as a distinction from storage that provides slow-to-access information but offers higher capacities. If needed, contents of the computer memory can be transferred to secondary storage; a very common way of doing this is through a memory management technique called virtual memory. An archaic synonym for memory is store.
