I think its c or d but im not quite sure.....
I would use miles
Because miles will give you less of an answer
Answer:
Explanation:
The diffraction angles when we have a slit divided into parts are obtained by the following equation:
(1)
Where:
is the width of the slit
is the wavelength of the light
is an integer different from zero.
Now, the second-order diffraction angle is given when , hence equation (1) becomes:
(2)
Now we have to find the value of :
(3)
Then:
(4)
(5)
Finally:
(6)

the engine won't start or it sputters when it should be running perfectly. if the gasoline is old and stale, it will have lost a portion of its volatility. the lighter components of the gasoline (remember, gasoline is a mixture of different hydrocarbons) have probably evaporated off or disappeared.
