Answer:

The photosphere is the visible surface of the Sun that we are most familiar with. Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).

The performance planner is a tool which helps to obtain the best bids and mean monthly budget around all the campaigns.

The objective of a performance planner are:

  • Enhance the conversation number to achieve any upcoming spend premise.
  • Helps to obtain the best bids and mean monthly budget.
  • Provide the chance to get the benefit of seasonality opportunities.
  • Provides new possibilities to enhance the sales through ad and campaigns.

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) using your equation from step 2d, estimate the gpa of a student who studies for 15 hours a week. justify your answer.
Pavlova-9 [17]

Using previously given equation, the estimate of the GPA of a student who studies for 15 hours a week is; 3.1

<h3>How to predict an equation?</h3>

The equation here is probably a "best fit" equation based upon given data which is GPA versus the number of hours of study per week.

Now, the equation of best fit is given as;

y = 0.149x + 0.89

Thus, if the number of study hours of interest is 15, then the GPA is;

GPA =  0.149(15) + 0.89

GPA = 3.1
