2. A 15.0 N force is used to hold a mass on a string at an angle of 32° from the vertical, as in the below diagram.
32
F = 15.0 N
What is the mass? (ans: 2.9 kg)
As u can see I have the answer so plz just show ALL STEPS

2.9kg

let mass be=m ; F=15N; Sin(theta)=32°;g =9.8kgm/s^2.

represent the mass. By resolving forces, we have:

F=mgSin(theta)

15N=mgSin(32°)

m=15N/g×Sin(32°)

m=15N/9.8m/s^2×Sin(32°)

=2.888kg2.888

≈2.9kg

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

hope this ! this is not copied! search it up, it's free of plagiarism!

c) power lifting, will be your answer.
