The table shows the results of a 'favorite fruit' survey. Jim represented the data both as a bar graph and a line graph as shown. Which graph best represents the data? Favorite Fruit Number of Votes Apple 19 Mango 22 Pineapple 9 Others 17 => bar graph, because a bar gr..

ABCO is a trapezoid. Which statement would prove that the mid-segment of a trapezoid is parallel to the bases? => Distance from O to A = Distance from C to B = Distance from P to Q or (Slope of PQ ‾ × Slope of OA ‾ ) = - 1, (Slope of PQ &Over..

Facts and figures as such do not catch our attention unless they are presented in an interesting way. Graphical representation of data is one of the most commonly used modes of presentation. Graphs can not only be made attractive, but they are also easy to comprehend and do not take much timeh..

The science of magnetism is old. It has been known since ancient times that magnetic materials tend to point in the north-south direction: like magnetic poles repel and unlike ones attract; and cutting a bar magnet in two leads to two smaller magnets. Magnetic poles cannot..

The graphical representation of data makes the reading more interesting, less time-consuming and easily understandable. The disadvantage of graphical presentation is that it lacks details and is less accurate. In our study, we have the following graphs: 1. Bar Graphs 2. Pi..

The best method of making a powerful magnet is by passing electric current. Wind a length of an insulated copper wire around a steel rod DY and connect it to a battery and a switch. After the current has passed through the coil for some time you will notice that the steel rod gets ma..

Types of Magnets - There are two major types of magnets: Permanent magnets and Temporary magnets. Permanent magnets retain their magnetism over a long period of time whereas temporary magnets retain their magnetic properties only under certain conditions like presence of a strong magnet o..

>The amount of heat generated in a conductor of resistance 'R', when current 'I' flows through it in a given time 't', is given by I 2 Rt. Electric power is said to be one watt if a potential difference of one volt causes a current of one ampere to flow through a conductor. The magnetic f..

From the first discoveries of gold in ancient times, its beauty and the ease with which it could be worked inspired craftsmen to create it into ornaments, not just for adornment, but as symbols of wealth and power. The skills of the goldsmith from ancient Egypt to Benvenuto Cellini or Ca..
