Why are housing starts a key indicator of a nation’s economic well-being? Housing starts affect the health of a number of other important industries. Gross domestic product cannot be calculated without knowing the number of housing starts. Housing starts can be used as a measure of homelessness and, by proxy, unemployment. Residential construction is more important to the economy than commercial or industrial construction.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

1in2 processor chip can be modelled as an isothermal plane wall of silicon, isothermal on both sides. the power input to the bottom of the plane wall, or the processing power of the chip, often called the thermal design power (tdp), is 100w. assume the periphery is adiabatic. the silicon is 400 microns thick. the temperature at the junction, or in this case on the bottom of the isothermal plane wall, is 85°c. what is the top surface temperature, assuming that the only mode of heat transfer is conduction

Aparticle moves along a straight line such that its acceleration is a=(4t^2-2) m/s, where t is in seconds. when t = 0, the particle is located 2 m to the left of the origin, and when t = 2, it is 20 m to the left of the origin. determine the position of the particle when t=4s.
