Option 1 : Green cube

Concept :

Pressure :

  • It is the force that acts on a unit area of a surface called pressure.
  • Pressure = force / area on which it acts

Explanation :

  • The smaller the area, the larger the pressure on a surface for the same force.
  • Example: The area of the pointed end of the nail is much smaller than that of its head.
  • The same force, therefore, produces a pressure sufficient to push the pointed end of the nail into the wooden plank.
  • A green cube with a side of 0.25 cm will exert more pressure on a flat table as it has less area as compared to a red cube having a side of 0.35 m and a yellow cube of side 0.5 m.

So, the correct answer is the green cube.

  •  S.I.unit of pressure is Pascal.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since.  S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
