An ant is moving on thin (negligible thickness) circular wire. How many coordinates do you require to completely describe the motion of the ant?

An ant is moving on thin (negligible thickness) circular wire. How many coordinates do you require to completely describe the motion of the ant? Correct Answer Two

Concept:

  • In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space
  • In simple words Coordinate systems are used to describe the position of an object in space.
  • In the cartesian system, this coordinates of space are given by X, Y, and Z
  • If an object’s motion is limited only in once coordinate i.e., X or Y or Z, the motion is said to be moved in only one dimension
  • Similarly, if an object’s motion is described along with any two or three coordinates it is said to be in two or three dimensions respectively

 

Explanation:

  • As per our given condition, an ant is moving on a thin circular wire
  • Consider this circular wire placed on a flat surface
  • the motion of ant is described using X and Y coordinates as we can see below

A telephone switchboard 100 pair cable can be made up with either enameled wire or tinned wire. There will be 400 soldered connections. The cost of soldering a connection on the enameled wire will be P 1.65 on the tinned wire, it will be P 1.15. A 100- pair cable made up with enameled wire cost P 0.55 per linear foot and those made up of tinned wire cost P 0.75 per linear foot. Determine the length of cable run in feet so that the cost of each installation would be the same.

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: Specialty steel and wire ropes maker Usha Martin's decision to sell one of its core businesses - steelmaking - to prune outstanding debt, marks the rare instance of an Indian corporate borrower meeting its loan obligations through divestment. The slump sale is a milestone in the six-decade history of the Kolkata-based company, whose board on Saturday approved the divestment of its one million ton steel business in favor of Tata Steel for Rs 4,600 crore.  Courses of action: I. Proceeds will be used to ‘first repay existing lenders of the company’. Usha Martin will retain a profitable wire ropes unit as residual business, and has plans to scale it up significantly.  II. As part of the transaction, Usha Martin has entered into a five-year deal with The Tatas for sale of steel at market price to the wire-ropes business.  III. Usha Martin is among the top four wire rope players globally. With oil prices going up and strong trend in demand in Europe, the Ebitda in the wire-ropes business has improved.
