The Bretton Woods Agreement was finalised in July 1944 at Bretton Woods in New Hampshire, USA. It established the International Monetary Fund and the World Bank to preserve global economic stability and full employment in the industrial world. These institutions also dealt with external surpluses and deficits of member nations, and financed post-war reconstructions.

One of the main reason why the copper vessels lose their shine when exposed to air is due to the passivization.

When copper forms as protective layer of oxidation on the surface for preventing the further deterioration then material would be around the normal condition.

At the surface of vessel, Copper atoms react with the Oxygen atoms in the air forming copper-oxide.

Electric potential at a point in an Electric field (for instance, let's take it as uniform) is the amount of work done in moving a unit positive charge from infinity to that point against electric forces. (attraction or repulsion)

whereas Electric potential difference between two points in an Electric field is defined as the amount of work done in moving unit positive charge from one point to another point against the electric force.

In other words, Potential difference is simply the difference of scalar potentials between two points or anything you consider.

Statistics is a form of mathematical analysis that uses quantified models, representations and synopses for a given set of experimental data or real-life studies. Statistics studies methodologies to gather, review, analyze and draw conclusions from data. The two main branches of statistics are descriptive statistics and inferential statistics. Both of these are employed in scientific analysis of data and both are equally important for the student of statistics.

The human eye can focus objects at different distances by adjusting the focal length of eye lens due to the power of accomodation of human eye.

Accounting as Science: Science is an organised body of knowledge based on certain basic principles. Therefore, accounting is also a science as it is an organised body of knowledge based on certain accounting principles.

Formula of curved surface area of cone = πrl 

Where r is radius and l is slant height

Since we are given slant height is 10 cm and base radius is 7cm

So, Curved surface area of cone = 3.14 × 25 ×7

                                                      = 549.5

Hence the curved surface area of cone is 549.5 cm square.

Angstrom (Å), unit of length used chiefly in measuring wavelengths of light, equal to 10−10 metre, or 0.1 nanometer. One angstrom is equal to 10−10 m (one ten-billionth of a meter or 0.1 nanometers). Although the unit is recognized world-wide, it is not an International System (SI) or metric unit. It is named for the 19th-century Swedish physicist Anders Jonas Ångström.

A climate is that average weather in an exceeding place over a few years. Whereas the weather would be an amendment in the matter of mere hours, the environment takes a whole bunch viz. thousands of years to alter. However, it is dynamic and rising at an alarming rate over the past few years.

 Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial. In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

Genetics is a branch of biology which explains the transmission of body characteristics both, similarities and differences, from parents to the offspring. The groundwork on which heredity stands is known as inheritance. It is defined as the procedure by which characteristics are handed down from one generation to the other. Gregor Johann Mendel is known as the “Father of Modern Genetics” for his discoveries on the basic principles of heredity.

Molar mass of NaOH = 40g per mole
no. of moles in 5g of NaOH = 5/40 =0.125
volume of solution=450mL= 0.45 L
molarity of solution=no.of moles of solute/volume of solution
                              =0.125/0.45
                              =0.277777777778=0.28(approx.)
