Answer:

Explanation:
= Intensity of unpolarized light = 
= Angle of the filter = 
Intensity of light is given by

The intensity of light detected by the camera is 
Time taken by the package to reach the sea level= 13.7 s
height=h=925 m
initial velocity along vertical= vi=0
acceleration due to gravity=g=9.8 m/s^2
using the kinematic equation h= Vi*t + 1/2 gt^2
925=0(t)+1/2 (9.8)t^2
4.9 t^2=925
t= 13.7 s
Explanation:
The intense gravity of the black hole would pull you apart, separating your bones and muscles.
It's a physical change. the water is changing it's physical state
