E. Corrosion-resistant steels.

Define what a glass transition is and what happens to a polymer because of it

Real resistors can only be manufactured to a specific tolerance, so that in effect the value of the resistance is uncertain. For example, a 1Ω resistor specified as 5% tolerance could in practice be found to have a value anywhere in the range of 0.

Some designers suggest that speech recognition should be used in a telephone menu system. This would allow users to interact with the system by speaking instead of pressing buttons on the dial pad.

Consider a 1000-W iron whose base plate is made of 0.5-cm-thick aluminum alloy 2024-T6 (rho = 2770 kg/m3 and cp = 875 J/kg·°C). The base plate has a surface area of 0.03 m2. Initially, the iron is in thermal equilibrium with the ambient air at 22°C.

The rate at which velocity changes is called?

Roentgens are used to measure the amount of: uranium fuel burned radiation hydrogen isotopes

What is the maximum % carbon for structural steel?

An airplane flies from San Francisco to Washington DC at an air speed of 800 km/hr. Assume Washington is due east of San Francisco at a distance of 6000 km.
