Dermis is the second layer of skin. It's much thicker and does a lot for your body.
Subcutaneous fat is the bottom layer.
Hope I helped.
Answer:
The resultant displacement is the sum of displacement vectors
Explanation:
The vector sum of two or vectors is know as resultant .
The resultant displacement is the result of when displacement vectors are added.
If the vector quantities are same then the two vectors can be added.
The resultant velocity is obtained by adding two or more velocity vectors.
In displacement vector the position will change.
The direction traveled is the direction of the displacement vector .
The magnitude of the displacement vector is the distance from starting point to the ending point.
Yes it is a chemical reaction
I think the answer should be D.<span>It reduces the amount of thermal energy that is transferred from outside to inside the container. </span>
