I think the answer is repulsive.... Sorry if I get this wrong? :)
I think that would be c) mirror because mirrors reflects light and can't create it.
That they travel in a vacuum. All other waves require a medium in which they wave.
Answer:
The Density of the block is 4.667g/mL
Explanation:
Given the following data;
Mass of block = 700g
Volume of block = 150cm³
Density = ?
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;

Substituting into the equation, we have;

<em>Density = 4.667g/mL</em>
