The pressure exerted by a liquid column at the bottom of the liquid co...
  • Pressure in liquids is the multiplication of three quantities i.e. 
  • Where:
    • is the pressure at the depth,
    • ρ is the density of the fluid,
    • is the acceleration due to gravity, and
    • is the depth or height of the fluid column.
  • Option 1 - Dependent on the density of the liquid
    • Pressure is directly proportional to the density (ρ) of the liquid.
    • As the density increases, the pressure at a given depth also increases.
  • Option 2 - Equal in all directions
    • Pascal's Law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase in pressure throughout the fluid in all directions.
    • In the context of a liquid in a container, this means that the pressure at the bottom of the container is transmitted equally in all directions to the sides and top of the container.
  • Option 3 - Not dependent on the area of cross-section of container
    • As per the formula, the pressure (P) is not directly dependent on the area of cross-section (A) of the container. 
    • The pressure is primarily influenced by the height, density, and acceleration due to gravity.

Similar EmSAT Achieve Doubts

On attending a conference, which focused on the role of the services sector in Indian economy I was amazed. The conference gave a very interestingperspectiveon the role of the service sector in the growth of Indian economy in relation to growth rates in agriculture and industry. The current situation in India is that the growth rate of services has overtaken both agriculture and industry and is now contributing to more than 50% of GDP. The service sector has the highest growth rate and is the leastvolatilesector. Growth is particularly marked in public services, IT and financial services.In some areas, the growth rate of the service sector is 40-50% due to increased use of mobile technologies. India, therefore has, a service-oriented economy. It hasnt followed traditional growth models as in China. However, in the process of doing so it has skipped the manufacturing stage and has jumped straight from the agriculture stage to service stage, which is also the main reason for the expansion of the service sector. In fact, the situation now is such that the growth in the service sector can and will support in the agriculture and industrial sectors. However, the only setback for Indian economy is the lack of growth in the manufacturing sector which causes dependence on other countries, which is not so desirable in terms of job creation and increased prosperity.Population is also a major concern of the Indian economy. As the population of India grows so also does the number of dependents in the population in both the lower and higher age groups. In such a scenario of increasing population, especially in an economy which still recovering from crisis, growth becomes difficult. For such an economy to grow it has to invest. Currently, the public sector invests more than it saves. The household sector saves in surplus, but it is not increasing so it cannot continue to support private and public sectors. There is a massive need to spend on agriculture and infrastructure development of the country. Apart from that health and education should also be the priority of the government particularly the education of women in order to reduce the birth rate.According to the passage, which of the following is/ are true about the impact of increasing population on Indian economy?A. If India attempts to absorb all the labour force, it will impact the growth of service sector negatively and in turn hamper the economic growth of the country.B. As the population of the country increases, the number of dependants in the country also increase which in turn increases the pressure on the economy.C. An increasing population can never lead the economy of the country towards prosperity; in fact it can only put strain on the economy of a country.
