While floating, the top of each ball is 4 cm above the paint surface. Now, if the paint is in a cuboid shaped vessel with base dimensions as 100 cm × 10 cm and height 10 cm; and there are 2 balls floating in this vessel, the total area in blue that a bird flying exactly above the vessel sees is: OPTIONS     1)   2)   3)   4) discuss | yesterday's solution | more questions Tip of the Day Some DI questions like highest increase, sharpest fall etc. that involve line graphs can be answered by looking at the slope of the graphs. One need not calculate actual values using absolute figures for these questions. more tips Last year's Question of the day (31-Oct-10) It is now well known that tiny fragments of graphene sheets are produced (along with quantities of other debris) whenever graphite is abraded, such as when drawing a line with a pencil. There was little interest in this graphitic residue before 2004/05 and, therefore, the discovery of graphene is often attributed to Andre Geim and colleagues who introduced graphene in its modern incarnation, although it may be argued that this is no more accurate than attributing the discovery of America to Columbus. In 2008 graphene produced by exfoliation was one of the most expensive materials on Earth, with a sample that can be placed at the cross section of a human hair costing more than $1,000 as of April 2008 (about $100,000,000/cm2). Since then, exfoliation procedures were scaled up, and now companies sell graphene by the ton. What can we infer about Columbus' discovery of America from this passage? OPTIONS     1) That it was an inaccurate attribution.   2) That there were multiple versions of the account, and anything can be inferred from those.   3) That since America existed before Columbus discovered it, the attribution is false.   4) That it was actually Andre Geim who discovered it.   5) That its accuracy is disputed. discuss TestFunda.com - LEARN with THE LEADER in Online MBA Test Prep Demo Lessons   |   Take a Free Test   |   Buy Courses   |   Fun Learning Games   |   100-Percentilers About TestFunda.com - TestFunda is backed by www.ZeusLearning.com. 4 IIT-IIM graduates form the Management Team. - The 85+ member team has vast experience in MBA Coaching and Computer-Based Training and Testing. - For 9 years Zeus has created award-winning courseware for companies like Discovery Channel, Reader's Digest, Texas Instruments, Pearson Education. - The TestFunda Advisory Board comprises CEOs and MDs of international educational companies.
