The Earth is not a uniform sphere, but has regions of varying density. Consider a simple model of the Earth divided into three regions-inner core, outer core, and mantle. Each region is taken to have a unique constant density (the average density of that region in the real Earth): Part A Use this model to predict the average density of the entire Earth. Region Radius (km) Density (kg/m³) Express your answer to three significant figures and include the appropriate units. Inner Core 0 – 1220 13, 000 HẢ Outer Core 1220 – 3480 11, 100 3480 – 6380 4400 ? Mantle P3 regions = Value Units Submit Request Answer Part B If the radius of the Earth is 6380 km and its mass is 5.98 x 1024 kg, determine the actual average density of the Earth. Express your answer to three significant figures and include the appropriate units. HÀ ? Paverage = Value Units Submit Request Answer

Fire safety

Fire safety is a new domain emerged in the early 90s to enable the design of buildings, structures, and infrastructure against destruction through fire. It also includes the provisions of building codes. This field is mostly associated with the design and efficient planning of a building, to reduce the destruction caused by fire. The branch of engineering that deals with it for the safety of the buildings from destruction of fire, is known as fire safety engineering.
