Why is the Sky Blue?

So we see more blue than any other colour and this makes the sky look blue.

  The Strait of Hormuz is a narrow waterway between Iran and Oman that connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. At its narrowest point, it is about 21 nautical miles (39 kilometers) wide, with designated shipping channels for vessels entering and leaving the Persian Gulf. Its location makes it one of the world's most important maritime chokepoints. Its importance comes mainly from the amount of energy that moves through it. The International Energy Agency says an average of about 20 million barrels of crude oil and oil products passed through the strait each day in 2025, representing roughly one-quarter of global seaborne oil trade. The U.S. Energy Information Administration also estimates that about one-fifth of global liquefied natural gas trade passed through Hormuz in 2024, much of it from Qatar.

R ailway signals control the movement of trains. They help to keep the trains away from each other to avoid collisions and also keep them running efficiently and on time. The block is the basis of a signalling system. It is a stretch of line in one direction. No more than one train can be in a block at a time . A stop signal controls entry into the block. If it is red, the driver has to stop there. A distant signal before the start of a block warns the driver of what the stop signal will show, so if necessary, he can start to slow down.

What are Computer Graphics?

-
Image
Computer graphics are pictures produced by computer. They may appear on screen or be printed on paper. Almost all the computer games and now business , scientific and engineering programs use graphics. The graphics with their colour and drawings prove to be more informative than when explained in words. The use of graphics in Computer Aided Design (CAD ) can help in designing a small object to a space craft. Engineers use computers in the designing of more efficient vehicles. Small changes can be made to the design and their effects can be observed without having to redraw the whole object and make a new model for testing.

Each end has a set of three wickets , each wicket's height is 28 inches and they are placed at the width of nine inches. Cricket originated in India during British rule.
