General Science Questions

Hydroplaning is caused by a combination of standing water on the road, car speed, and under-inflated or worn-out tires.

The national flag of India has 4 colours saffron, white, green and navy blue. Each describes a specific reason.

Saffron - It represents the courage and sacrifice

White - It represents eace, truth and purity

Green - It represents faith, fertility and growth

The wheel of virtue which is in navy blue represents the motion of growth.

All of us, believe that the Solar System evolved from a giant cloud of dust and gas. They believe that this dust and gas began to collapse under the weight of its own gravity. As it did so, the matter contained within this could begin moving in a giant circle, much like the water in a drain moves around the center of the drain in a circle.

At the center of this spinning cloud, a small star began to form. This star grew larger and larger as it collected more and more of the dust and gas that collapsed into it.

Further away from the center of this mass where the star was forming, there were smaller clumps of dust and gas that were also collapsing. The star in the center eventually ignited forming our Sun, while the smaller clumps became the planets, minor planets, moons, comets, and asteroids.

The Economic and Social Council (ECOSOC) is one of the six principal organs of the United Nations for coordinating the economic, social and environmental issues, as well as for implementing internationally agreed development goals. Recently, it is in news because India has been re-elected to the United Nations ECOSOC for another 3-year term. India was among 18 nations to win election to the Economic and Social Council (ECOSOC). India obtained 183 votes, the second highest after Japan in the Asia Pacific category. The elected members of ECOSOC for a three-year term beginning 1 January, 2018 are Belarus, Ecuador, El Salvador, France, Germany, Ghana, India, Ireland, Japan, Malawi, Mexico, Morocco, Philippines, Spain, Sudan, Togo, Turkey and Uruguay. The headquarters of the ECOSOC is located in New York, Unites States.

The shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake that does not receive any direct P waves. The shadow zone results from S waves being stopped entirely by the liquid core and P waves being bent (refracted) by the liquid core.

There are two types of Shadow zones:

one for P waves and

one for S waves.

P wave shadows between 104-140 degree, both sides; S wave shadow from 105 of one side to 105 of the other.

Now a days, printers we are using are called as laser printers. The speed of a laser printer is measured in PPM i.e, Pages Per Minute. 

Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.

Compared to inkjet printers which use ink for printing laser printers are more expensive as they use toner which lasts for long.

MICR stands for Magnetic Ink Character Reader.
