Archimedes principle states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. The principal applies to both floating and submerged bodies and to all fluids, i.e. liquid and gases. If the body is denser than the fluid it will sink.

The noble gases are missing from Newlands' octaves because these elements were not known at that time. 

Mass of common salt (solute) = 40g
Mass of water (soluted) = 320g
Mass of solution = 320 + 40 = 360g
Concentration of solution = M(mass of solute) / mass of solution = 40/360 x 100 = 11.11%

• Zero Waste is a whole system approach to resource management centered on reducing, reusing, and recycling.
• Generally, “Zero Waste” is a philosophy of eliminating the generation of materials that have no viable or economic option for end-of-use management.

Metals have 1-3 electrons in their outermost orbit. They are present on the extreme left of the periodic table. They tend to donate electrons and obtain the stable electronic configuration of the nearest noble gas. The valency on metals also ranges from 1-3 .

The iris consists of two sheets of smooth muscle with contrary actions : expansion and contraction. These muscle control the size of the pupil and thus determine how much light reaches the sensory tissues of the retina.

According to the Newton’s Second Law of Motion, the change in momentum of a body per unit time is directly proportional to the unbalanced force acting on the body and the change in momentum takes place in the direction of the unbalanced force of the body. It can be represented as F = ma. From the equation we can see that mass is inversely proportional to acceleration so if the acceleration of the body increases by 4 times, the mass of the body will reduce by 4 times.

If the particles of the medium vibrate in a direction perpendicular to the direction of propagation of the wave, it is called a transverse wave. In transverse waves, the particle movement is perpendicular to the direction of wave propagation.

Explanation: Sexual reproduction involves the participation of two parents for the process of reproduction. During fertilization, the fusion of male and female gametes results in the creation of a zygote with a full set of chromosomes. This leads to the sharing of genetic information between the parents.

The correct answer is Clay.Key Points

• Clayey soil retains the highest amount of water and sandy soil retains the lowest amount of water.
• Clay soil is soil that is comprised of very fine mineral particles and not much organic material. 
• Clay is the smallest particle among the other two types of soil.
• The particles in this soil are tightly packed together with each other with very little or no airspace.
• This soil has very good water storage qualities and makes it hard for moisture and air to penetrate into it.
  • It is very sticky to the touch when wet, but smooth when dried. 
• Clay is the densest and heaviest type of soil that does not drain well or provide space for plant roots to flourish.

Additional Information

• Sand is a granular material composed of finely divided rock and mineral particles.
  • Sand has various compositions but is defined by its grain size.    
• Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz.
  • Silt may occur as soil or as sediment mixed in suspension with water. 
• Loam is soil composed mostly of sand, silt, and a smaller amount of clay.
