the scores of different students in math and science tests are shown in the bar graph. whose score is same on both the tests?

The scores of different students in Math and Science tests are shown in the bar graph. Whose score is same on both the tests? => John or Bob or Mathew or Edd..

v-t Graph - Let us now see the nature of the v - t graph for the different types of motion. a) Increasing acceleration Uniform Acceleration -------------------------------- Non-uniform Acceleration b) Decreasing acceleration Non-uniform Retardation --------------------..

Power - Imagine two students positioned at track A and track B of 100 m length shifting 10 bricks from one end of the track to the other end. What is the amount of work done by each one of them? The amount of work done is same but the time taken to perform the work varies. In order to fin..

The comparative anatomical studies of various types of organisms show structural and functional differences and similarities between various species. For example, the basic structure of all the flowers is the same with the whorls of calyx, corolla, androecium and gynoecium. However, each..

Once, a very beautiful actress met the famous English playwright, George Bernard Shaw. She wanted to propose to him and whispered, "Will it not be wonderful if our child has my beauty and your brains?" To this Bernard Shaw retorted, "What if the child has your brains and my looks!" What do you thi..

A solenoid is a long coil (shaped like a cylinder) containing a large number of close turns of insulated copper wire. The figure above shows a solenoid SN whose ends are connected to a battery B through a switch X. When a current is passed through a solenoid, it produces a magnetic field around ..

Take a nichrome wire of about 50 cm length and apply a potential difference of 1.5 V from a battery. Measure the current flowing through the wire using an ammeter connected to it in series, and note the potential difference across the resistance using a voltmeter connected acro..

Solar cell is a very thin sandwich of n-type and p-type wafer thin semiconductors of silicon. A U-shaped metal grid is embedded into the thin semiconductor chip as shown in the fig. The lower end of the sandwich is fixed to a metal base which has a metal lead. The grid has a lead contac..

Summary - An electric current produces a magnetic field A magnetic field exists in the region surrounding a magnet, in which the force of the magnet can be detected Field lines are used to represent a magnetic field The magnetic field lines of a straight current are circular with centres on the wir..

The plant hydrangea can have pink "flowers" or blue "flowers" (they're actually modified leaves). But we do not classify the two forms as different species. In fact, one could allow a blue-"flowered" plant to become a pink-"flowered" plant just by changing the pH of the soil and the amoun..
