2. Step-by-step explanation:

Given A string diameter is 1 mm is kept on a table in the shape close flat spiral , a spiral with no gap between turns.The area of the table occupied by spiral is 1 m square. then the length of the string is

• Given A string is placed on a table. It resembles the shape of a close flat spiral and there is no gap in between the turns..
• Now the area occupied by the spiral is given as 1 m^2 and the diameter of a string is 1 mm = 1 x 10^-3 m
• The total spiral can be made pulled and made it straight to form a straight line which forms a horizontal straight line.
• Let the length be l
• So the total horizontal area will be length x diameter
•                                                Area = l x d
•                                             1 m^2 = l x 1 x 10^-3 m
•                                             Or 10^-3 m x l = 1 m^2
•                                              Or l = 1m^2 / 10^-3 m
•                                                Or l = 10^3 m
