A 100-n weight is hung at the middle of a 4-m long horizontal clothesline. If the middle of the clothesline sags by 1 m, what is
Elena L [17]

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

A bag contains only blue and red marbles.Asman takes 1 marbles at random out of a bag. Probability that she takes a red marble o
Amiraneli [1.4K]
At first situation, ratio = x/y = 1/5
5x = y  -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5

Substitute the value of y from equation (1), 
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5

Originally, There were 5 red marbles in the bag

Hope this helps!

Umnica [9.8K]

The time guests should arrive for the 9 am opening is 8:30am.

When guests are expected at an event, best practice is to arrive 15 minutes before the opening time. If 30 minutes is subtracted from 9am it is 8:30 am.

If guests aim to arrive at exactly at 9am, it is likely that they would not be at the opening on time.

Here are the options to this question: A. 1 a.m. B. 9 a.m. C. 6 a.m. D. ​8:30 a.m.
