Carbon and oxygen are two substances that are linked in one recycling process
Answer: D. The force and displacement are in the same direction.
Explanation:
The Work 
done by a Force 
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path with distance 
.
Work is a scalar magnitude, and its unit in the International System of Units is the Joule (like energy).
Now, when the applied force is constant and the direction of the force and the direction of the displacement are <u>parallel</u>, the equation to calculate it is:
(1)
When they are not parallel, both directions form an angle, let's call it 
. In that case the expression to calculate the Work is:
(2)
When the force and displacement are perpendicular to each other,
and <u>no work is done</u>.
It is a synthesis reaction where two reactants gives one product.
Answer:option D
2Mg + O2 ------> 2 MgO
Answer:
What is a Free Body Diagram?
The free body diagram helps you understand and solve static and dynamic problem involving forces. It is a diagram including all forces acting on a given object without the other object in the system. You need to first understand all the forces acting on the object and then represent these force by arrows in the direction of the force to be drawn.
Explanation:
It doesn’t, a new tooth underneath your old one starts to push the right old one out, then the tooth comes loose and the tooth underneath continues growing.
