Ahorizontal clothesline is tied between 2 poles, 14 meters apart. when a mass of 4 kilograms is tied to the middle of the clothesline, it sags a distance of 3 meters. what is the magnitude of the tension on the ends of the clothesline? tension =

The magnitude of the tension on the ends of the clothesline is 21.32 N.

Explanation:

Given that,

Distance = 14 m

Mass = 4 kg

Height = 3 m

We need to calculate the angle made with vertical mass

We need to calculate the magnitude of the tension on the ends of the clothesline

Using formula of tension

Put the value into the formula

Hence, The magnitude of the tension on the ends of the clothesline is 21.32 N.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
