Answer:
b. add a magnetic metal core
Explanation:
a p e x test
Answer:
x = 0.0873 m
Explanation:
given,
length of clothesline = 10 m
the line sags to create an angle that is 1 degree below the horizontal on each end.
As mass is hang at the center the angle made let the deflection be 'x'
as the shirt is hang at the center distance will be equal to 5 m.
now
x = 0.0873 m
Hence, the cloth line will be x = 0.0873 m from the original length of the clothesline.
