Answer:
.
Explanation:
The mechanical energy of the system will be the kinetic energy plus the elastic potential energy: 
.
We know that the equation for the kinetic energy is 
, where <em>m </em>is the mass of the object and <em>v </em>its velocity.
We know that the equation for the elastic potential energy is 
, where <em>k</em> is the spring constant and 
the compression (or elongation) respect to equilibrium.
So for our values we have:
.
Answer:
True
Explanation:
For any equation to be balanced, be it elemental equation or radioactive decay equation, the number of atoms on the left must balance the number of atoms of the right. The same is true for alpha decay as the number of protons on the left side must equal the number of protons on the right side?
Operant conditioning, sometimes called <em>instrumental learning</em>, was first extensively studied by Edward L. Thorndike, who observed the behavior of cats trying to escape from home-made puzzle boxes.
