The earthquake corresponding to the ultimate safety requirement is often termed as |
|
Answer» Explanation: The Indian subcontinent has suffered some of the greatest earthquakes in the world. The earthquakes of the late nineteenth and early twentieth centuries triggered a number of early ADVANCES in science and engineering related to earthquakes that are discussed here. Activities in the late 1950s to institutionalize EARTHQUAKE engineering in the country are also discussed. Despite these early developments towards seismic safety, moderate earthquakes in India continue to cause thousands of deaths, indicating the poor seismic resilience of the built environment. The Bhuj earthquake of 2001 HIGHLIGHTED a striking disregard for STRUCTURAL DESIGN principles and quality of construction. |

Write difference between of metals and non metals |
|
Answer» Explanation: Metals are Hard MEANWHILE the non-metals are soft. Metals are shiny meanwhile the non-metals are Matte( Opposite of Shiny). Metals are Sonorous meanwhile the non-metals are not Sonorous. Metals are having high melting points meanwhile the non-metals are having LESS melting point. Metals are having free ELECTRONS meanwhile the non-metals are having stable electrons. Metals shows the property of Ductility meanwhile the non-metals doesn't show the property of Ductility. Metals need LARGE amount of energy to break meanwhile the non-metals need less amount of energy to break. Eg. of Metals-- Iron, Aluminium,Gold, Sodium, Potassium, Mercury, etc. Eg. of Non - Metals-- Bucket, Glass, Wood, Leather, Plastic, etc. |

The elephant waste 20000n and assistant on one foot of area of 1000cm2 is how much pressure it exerts on the ground |
|
Answer» Answer: Given : Force (N) = 20,000 AREA = 1000cm² = 0.1m To FIND : Pressure Solution : Use the Formula : \large{\color{grey}{\boxed{\sf{Pressure = \dfrac{Force}{Area}}}}} Pressure= Area Force
Substituting the values gives : ╭☞ Pressure = \sf{\dfrac{20000}{0.1}} 0.1 20000
╭☞ Pressure = \sf{20000 \times 10}20000×10 ╭☞ Pressure = 20000pa So , the pressure is 200000pa or 200000n/m² Supplementary information : Force is something that is PUSH or pull. Force is of two types : Contact force and Non contact force. Area is the TOTAL area an object holds up . Pressure is the force of an object that is exerted on something Pressure can be measured in Pascals or pa . Pressure is Force per unti area : F/A |

Define Archimedes Principles |
|
Answer» Explanation: Archimedes' principle states that the UPWARD buoyant force that is exerted on a BODY immersed in a fluid, whether fully or PARTIALLY, is equal to the WEIGHT of the fluid that the body displaces. Archimedes' principle is a law of physics fundamental to fluid MECHANICS. It was formulated by Archimedes of Syracuse. hope it helps :) |
