Sedimentary rock I believe
A sphere has reflection symmetry across any plane through its center.
The stone's altitude at time
is given by

where
is the acceleration due to gravity. The stone reaches the ground when
:

False. That description fits the wave's 'frequency'.
It has nothing to do with refraction.
Direct variation involves ration and proportions, so
you need to set up the proportion:
<span>11 / 75 = x / 65
Cross multiplying:
75x = 11*65
x = (11*65)/75
Solving, we get x = 9.533, </span>
<span>which rounds off to 9.5
Therefore, the spring will stretch up to 9.5 inches with 65 attached.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
