The 49 parallel is a line of latitude that serves as a significant geographic boundary between Canada and the United States. It is an imaginary line that circles the Earth horizontally and is located at approximately 49 degrees north of the equator. The 49th parallel was established as a result of various treaties and agreements …
The Polar Front Theory is also known as the Polar Front Theory of Cyclones, is a meteorological concept that explains the formation and development of mid-latitude cyclones. It was developed in the early 20th century by Norwegian meteorologist Vilhelm Bjerknes and his colleagues, and it revolutionized the understanding of weather systems. The theory revolves around …
The Agulhas Current is a warm oceanic current that flows southward along the eastern coast of South Africa. It is one of the western boundary currents, which are strong, narrow, and fast-moving currents that flow along the western margins of ocean basins. The Agulhas Current is named after Cape Agulhas, the southernmost point of the …
The Benguela Current is a cold oceanic current that flows northward along the western coast of southern Africa. It is named after the Benguela region, which encompasses parts of Angola, Namibia, and South Africa. The current is part of the larger South Atlantic Gyre circulation system. Characterized by its cold waters, the Benguela Current is …
The Durand Line is a demarcation line that serves as the international border between Afghanistan and Indian (POK). It was established in 1893 by Sir Mortimer Durand, a British diplomat, during negotiations between the British Raj (India) and the Emirate of Afghanistan. The purpose of the Durand Line was to define the limits of British …
The formula for the difference of two cubes, a^3 – b^3, is a special case of the binomial expansion formula. It can be factored into (a – b)(a^2 + ab + b^2). Let’s break down the formula and understand its components: (a – b): This part represents the difference between the two values, where ‘a’ …
The diagonal of cube is a line segment that connects two non-adjacent vertices of the cube and passes through its center. In other words, it is a line segment that spans from one corner of the cube to another, passing through the center of the cube. For a cube with edges of length “a,” the …
To find the cube of a number, you need to multiply the number by itself twice. In mathematical notation, if you have a number “x,” its cube is represented as “x^3.” Here’s the formula: Cube of a number (x^3) = x * x * x For example, if you want to find the cube of …
The Surface Area of Cube refers to the total area of all its six square faces. Each face of a cube is identical and has the same dimensions, so calculating the surface area is relatively straightforward. To find the surface area of a cube, you need to know the length of one side (edge) of …
The volume of a cube refers to the amount of space occupied by the cube. A cube is a three-dimensional geometric shape with six square faces of equal size. Each face is perpendicular to the adjacent faces, and all edges have the same length. To calculate the it you need to know the length of …
