The tension on each segment of the clothesline is : 110 N
<u>Given data : </u>
mass of object = 100 n = 10 kg
Horizontal distance of clothesline = 4 m
middle of clothesline sag s by : 1m
<h3 /><h3>Determine the tension on each segment of clothesline</h3>
<u>First step</u> : calculate the horizontal angle made by the sagging
β = arctan ( 1 m / 2m ) ----- ( 1 )
= arctan ( 0.5 )
≈ 26.57°
Note : Tension in th y axis ( Ty ) = Tsinβ
Therefore :
Tension on each segment can be calculated using the formula below
2Tsinβ - mg = 0
solve for T
T = mg / 2sinβ
= ( 10 * 9.8 ) / 2 * sin 26.57°
= 98 / 0.89
= 110 N
Hence we can conclude that the tension on each segment of the clothesline is : 110 N

Neurofeedback involves trying to change brain wave activity.
<h3>Brain wave</h3>
The human brain is an intricate organ that baffles many scientists today. One design feature of the human brain is its ability to send signals in the form of brain waves when the mind is ar work or in a state of rest. These brain wave activity are braodly categorized into four types, namely;
- beta waves
- alpha waves
- theta waves
- delta waves
Neurofeedback thus occurs when an attempt is made to change from one of the above brain wave types to another.
