An electric field is a field or space around an electrically charged object where any other electrically charged object will experience a force. An electric field is measured by a term known as electric field intensity. In that case, line through which the positive unit charge moves, is called line of force. 

Electric field, an electric property associated with each point in space when charge is present in any form. ... The magnitude and direction of the electric field are expressed by the value of E, called electric field strength or electric field intensity or simply the electric field.

Micronutrients are nutrients that are required by the body in lesser amounts for its growth and development. They play a major role in the metabolic activities of the body. These include vitamins and minerals.
 

Types of Micronutrients

Micronutrients, i.e., vitamins and minerals can be divided into the following types:

Water-Soluble Vitamins

Most of the vitamins can be dissolved in water. They are difficult to store in the body and get flushed out in urine when consumed in large quantities. They play an important role in producing energy. Since they are not stored in the body, it is important to take them enough from different food sources.

Fat-Soluble Vitamins

These vitamins do not dissolve in water. These are stored in the liver and fatty tissues for future use. Vitamins A, D, E, and K are important fat-soluble vitamins. They play a major role in the proper functioning of the immune system, proper bone development, proper vision, and protection of cells from damage.

In India, Population data is collected through census operation which held every 10 years in our country. The spatial pattern of population distribution is very uneven. As some areas are sparsely populated whereas others are dense. These states can be categorised into three categories:

States with High Population Uttar Pradesh, (highest population), Maharashtra, Bihar, West Bengal, Andhra Pradesh, Tamil Nadu, Madhya Pradesh, Rajasthan,
Karnataka and Gujarat. These states together account for 76% of the population.

States with Moderate population Assam, Haryana, Jharkhand, Chhattisgarh, Kerala, Punjab, Goa.

States with Low population Hilly and tribal areas like Jammu and Kashmir, Uttarakhand, all North Eastern states (except Assam) and Union Territories excluding Delhi.

The population is mainly affected by climate, terrain and availability of water. For example, the North Indian Plains, deltas and coastal plains are densely populated, whereas the mountainous areas and interior areas of central and southern India have relatively low population.

Besides these, the evolution of settled and urbanisation are the socio-economic and historical factors of distribution of population.

The Great Depression was a severe worldwide economic depression that took place mostly during the 1930s, beginning in the United States. Between 1929 and 1932, worldwide gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. By 1930, 4 million Americans looking for work could not find it; that number had risen to 6 million in 1931. Meanwhile, the country's industrial production had dropped by half. In 1930, severe droughts in the Southern Plains brought high winds and dust from Texas to Nebraska, killing people, livestock and crops.
