An aluminum wing on a passenger jet is 36m long when its temperature is 18°c. at what temperature would the wing be 3 cm (0.03 m) shorter?

- 16.72° C

Explanation:

L = 36 m

T1 = 18° C

Let it is 3 cm shorter at T2.

ΔL = 3 cm = 0.03 m

ΔT = T1 - T2

coefficient of linear expansion for Aluminium, ∝ = 24 x 10^-6 / °C

Use the formula for the thermal expansion

ΔT = 34.72

T1 - T2 = 34.72

T2 = T1 - 34.72 = 18 - 34.72 = - 16.72° C

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.

explanation:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
