180 pounds (lb) converts to 81.647 kilograms (kg).
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: Fossil fuels power the machine that shakes the tree so the apples fall to the ground
Explanation: most machines are powered by fossil fuels
Answer: 43.58 min
Explanation:
Knowing the volume of a rectangular object is length x width x height, we have two volumes:


And we know it takes a time of 4 minutes to fill
.
If we want to know how long will it take the same hose to fill another tank with volume
, we can use the <u>Rule of three</u>, which is a mathematical rule to find out an amount that is with another quantity given in the same relation as other two also known:
---- 
---- 

Finally:

Answer:
The value of the maximum charge the cloud can hold Q = 177.08 coulomb
Explanation:
Given data
Electrical Field E = 4 ×

the maximum charge the cloud can hold is given by
Q = E A x ---- (1)
where A = area = 5 × 
x = electrical Permittivity of air = 8.854 × 
Q = (4 ×
) (5 ×
) ( 8.854 ×
)
Q = 177.08 coulomb
This is the value of the maximum charge the cloud can hold.
