The supersonic airliner concorde is 62.1 m long when sittingon
the ground on a typical(15degreesc) day. it is primarilymade of
aluminum. in flight at twice the speed of sound, friction with the
air warms the concorde's skin and causes theaircraft to lengthen by
25cm. (the passenger cabin is onrollers, and the airplane expands
around the passengers.) what is the temperature of the concorde's
skin in flight?

Explanation:

L = Initial length = 62.1 m

= Coefficient of linear expansion of Aluminium =

= Initial temperature = 15°C

= Final temperature

= Change in length = 25 cm

Change in length due to heat is given by

The temperature of the Concorde's skin in flight is

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
