Answer:
The electron has a negative charge and is found outside of the nucleus.
Explanation:
1.) Neutrons have no charge, not a negative charge.
2.) Neutrons are found inside the nucleus, not outside.
3.) Protons have a positive charge.

Let the cannonball be thrown at a height of h above ground.
Then the potential energy of the ball is
V = m*g*h
where
m = the mass of the ball
g = 9.8 m/s²
Also, the kinetic energy of the ball is
K = (1/2)mu²
where
u = 5 m/s, the vertical launch velocity.
Ignore wind resistance.
Because the total energy is preserved, the total energy (n the form of only kinetic energy) when the ball strikes the ground is
(1/2)mV²
where V = vertical velocity when the ball strikes the ground.
Expressions for both the initial and final energy are equal regardless of whether the ball s thrown downward or upward.
Therefore there is no difference in the landing speed.
Answer: There is no difference.
The kinetic energy increase because as temperature warms up particles move faster
Answer Part A: radiation
Part B: conduction
Part C: conduction
Part D: conduction
Part E: conduction
Part F: radiation
Part G::radiation
Part H : convection
Explanation:conduction is heat transfer through direct contact
Convection is through molecules or particles of water or air current
Radiation is heat transfer through empty space .
