Answer:
Reflective
Explanation:
The radiation pressure of the wave that totally absorbed is given by;
and While the radiation pressure of the wave totally reflected is given by;
Now compare the two-equation you can clearly see that the pressure due to reflection is larger than absorption therefore the sail should be reflective.
It’s A liquid to a solid because if it’s a liquid they can move but not much and then it becomes a solid because they are packed closely together and are fixed in one position.
KE= 1/2 mv^2

The mass of the larger ball has TWICE
the kinetic energy. KE is directly proportional to the mass.
