  What is Pascal’s Law? According to Pascal’s Law, “The external static pressure applied on a confined liquid is distributed or transmitted evenly throughout the liquid in all directions”. The static pressure acts at right angles to any surface in contact with the fluid. Pascal also found that the pressure at a point for a static fluid would be the same across all planes passing through that point in that fluid. Pascal’s law is also known as Pascal’s principle or principle of transmission of  fluid-pressure . In 1653, Pascal law was stated by French mathematician Blaise Pascal. Pascal Law Formula Following is the formula of Pascal law: F = PA Where F is the force applied, P is the pressure transmitted, and A is the cross-sectional area.

  The Tissues A tissue is a collection of cells that share a common origin and function. A plant is made up of a variety of tissues. Meristematic and permanent tissues are the two types of tissues. This is founded on affecting the cells' ability to divide. Meristematic tissue cells can divide, whereas permanent tissue cells do not split any farther. 1. Meristematic Tissues Plant growth is primarily limited to meristems, which are specialised regions of rapid cell division. Meristems come in a variety of shapes and sizes.  Meristems are classified into two types based on their origin: primary and secondary. I. Primary Meristem Primary meristems create the primary plant body and are present early in the life of a plant. There are two types of primary meristems: apical and intercalary meristems. Apical meristem The apical meristem is a type of meristem that is found at the tips of shoots and roots. They are responsible for the production of primary tissues. Shoot apical meristem ...

  Why did Lencho say the raindrops were like ‘new coins’? Answer: Lencho compared the raindrops to ‘new coins’ – the big drops as ten-cent pieces and the little ones as fives. As his crops were ready for harvest, he hoped that the rains would bring him prosperity; so he felt the raindrops were like ‘new coins’. Question 4: What were Lencho’s feelings when the hail stopped? Answer: After the hailstones stopped, Lencho’s soul was filled with grief and dismay. He realised that everything was ruined by the hailstorm and nothing was left to feed his family for the entire year. He could visualize the bleak future of his family. Who read the letter? Answer: The postmaster read Lencho’s letter addressed to God. Who or what did Lencho have faith in? What did he do? Answer: Lencho had a strong faith in God. He believed that God’s eyes see everything, even what is deep in one’s conscience. Hence, he wrote a letter to God citing that he needed a hundred pesos to sow his field that was destroye...
