Answer:
The mechanical energy is converted to potential energy while the kinetic energy is zero
Explanation:
mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The total mechanical energy is the sum of these two forms of energy.
The Law of Conservation of Energy: Energy cannot be created or destroyed, but is merely changed from one form into another. This means that potential energy can become kinetic energy, or vice versa, but energy cannot “disappear”.
The mechanical energy is converted to potential energy while the kinetic energy is zero
Answer:
a) 
b) 
Explanation:
Searching the missed information we have:
E: is the energy emitted in the plutonium decay = 8.40x10⁻¹³ J
m(⁴He): is the mass of the helium nucleus = 6.68x10⁻²⁷ kg
m(²³⁵U): is the mass of the helium U-235 nucleus = 3.92x10⁻²⁵ kg
a) We can find the velocities of the two nuclei by conservation of linear momentum and kinetic energy:
Linear momentum:
Since the plutonium nucleus is originally at rest, 
:
(1)
Kinetic Energy:
(2)
By entering equation (1) into (2) we have:
Solving the above equation for 
we have:
And by entering that value into equation (1):
The minus sign means that the helium-4 nucleus is moving in the opposite direction to the uranium-235 nucleus.
b) Now, the kinetic energy of each nucleus is:
For He-4:
For U-235:

Answer:
True
Explanation:
An electric field is a region around a charged particle or object within which a force would be exerted on other charged particles or objects.
Answer:
2) Denotative meaning of a word or Denotation.
3) Connotative meaning of a word or Connotation.
4) Ethics and Culture.
Explanation:
2) Which meaning of a word refers to exactly what it is?
The denotative meaning of a word represents the explicit or the exact meaning of that word. Also called the denotation of the word.
3) Which meaning of a word includes what the word may represent?
The Connotative meaningof a word means something suggested or implied by a word. Also called the Connotation of the word.
4) What is the term used for society's tried and true rules that guide life?
Ethics refer to the rules and standards that guide the conduct of individuals; especially members of a societal body.
Culture is the total way of life of a society.
Hence, ethics amd culture both serve as the society's tried and tested rules that guide life.

This should be valence electrons. They determine the chemical properties of an atom.
