Answer:
1000.66m
Explanation:

L1=1000m
Temperature 1=-20
L2=?
Temperature 2=40
Temperature difference=40-(-20)
40+20=60
inserting into the formula
l2=l1(1+α×changeintemperature)
L2=1000(1+11×10^-6 ×60)
L2=1000(1+6.6×10^-4)
L2=1000(1.000.66)
L2=1000.66m
Since displacement is a vector quantity, it depends on direction as well as magnitude.
Taking displacement towards east as positive and towards west as negative,
Total displacement = 1200 + (-760) = 440 meters.
Since distance is a scalar quantity, it depends only upon magnitude.
Total distance = 1200 + 760 = 1960 meters.
Hope this cleared your doubt, feel free to ask any questions regarding this and have a nice day ahead! :)
