To solve this problem we will use the linear motion description kinematic equations. We will proceed to analyze the general case by which the analysis is taken for the second car and the tenth. So we have to:
Where,
x= Displacement
= Initial velocity
a = Acceleration
t = time
Since there is no initial velocity, the same equation can be transformed in terms of length and time as:
For the second cart
When the tenth car is aligned the length will be 9 times the initial therefore:
When the tenth car has passed the length will be 10 times the initial therefore:
The difference in time taken from the second car to pass it is 5 seconds, therefore:
From the first equation replacing it in the second one we will have that the relationship of the two times is equivalent to:
From the relationship when the car has passed and the time difference we will have to:
Replacing the value found in the equation given for the second car equation we have to:
Finally we will have the time when the cars are aligned is
The time when you have passed it would be:
The difference between the two times would be:
Therefore the correct answer is C.
Answer:
All mammals share at least three characteristics not found in other animals: three middle ear bones, hair, and the production of milk by modified sweat glands called mammary glands. Hair has several functions, including insulation, color patterning, and aiding in the sense of touch.

i have no clue, sorry. jus tryna get points
Answer:
A positive ion is formed by the removal of electron(s) from an atom or group of atoms.
A negative ion is formed by the addition of electron(s) to an atom or group of atoms.
Explanation:
A positive ion, also known as cation is formed by the removal of electron(s) from an atom or group of atoms until there are fewer electrons than protons. It positive ion because it contains more proton than electron.
A negative ion, also known as anion is formed when an atom or group of atoms gains electron(s) until there are more electrons than protons. It negative ion because it contains more electron than proton.
