If the two wires make the same angle with the vertical, what must this angle be if the tension in each wire is equal to 0.75 of the weight of the frame? (neglect any friction between the wall and the picture frame).

The angle is 48.24°.

Explanation:

Given that,

Tension

Let be the angle of wires with vertical

The total force in vertical direction from the wires

We need to calculate the angle

Using balance equation

Put the value of T in the equation

Hence, The angle is 48.24°.

the answer would be 32*f

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.
