Answer:
Galvanic Cell / Voltaic Cell
There are two types of electrochemical cells: galvanic, also called Voltaic, and electrolytic. Galvanic cells derives its energy from spontaneous redox reactions, while electrolytic cells involve non-spontaneous reactions and thus require an external electron source like a DC battery or an AC power source.
The acceleration of the car is determined as 0.626 m/s².
<h3>
What is acceleration?</h3>
The acceleration of an object is the change in velocity of the object with time.
a = Δv/t
where;
- Δv is change in velocity
- t is the time of motion
Substitute the given parameters and solve for the acceleration.
v = 14 mph = 6.258 m/s
a = (6.258 m/s) / (10 s)
a = 0.626 m/s²
Thus, the acceleration of the car is determined as 0.626 m/s².

#SPJ1
The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.)
To solve this problem it is necessary to apply the concepts related to Normal Force, frictional force, kinematic equations of motion and Newton's second law.
From the kinematic equations of motion we know that the relationship of acceleration, velocity and distance is given by
Where,
Final velocity
Initial Velocity
a = Acceleration
x = Displacement
Acceleration can be expressed in terms of the drag coefficient by means of
Frictional Force
Force by Newton's second Law
Where,
m = mass
a= acceleration
Kinetic frictional coefficient
g = Gravity
Equating both equation we have that
Therefore,
Re-arrange to find x,
The distance traveled by the car depends on the coefficient of kinetic friction, acceleration due to gravity and initial velocity, therefore the three cars will stop at the same distance.
