Indeed because some leave headlights off and ignore that fact since there are street lights around.
Answer:
t = 120.5 nm
Explanation:
given,
refractive index of the oil = 1.4
wavelength of the red light = 675 nm
minimum thickness of film = ?
formula used for the constructive interference
where n is the refractive index of oil
t is thickness of film
for minimum thickness
m = 0
t = 120.5 nm
hence, the thickness of the oil is t = 120.5 nm
a). for velocity, you must have a number, a unit, and a direction.
Yes. This one isn't bad. The 'number' and the 'unit' are the speed.
b). the si units for velocity are miles per hour.
No. That's silly.
'miles' is not an SI unit, and 'miles per hour'
is only a speed, not a velocity.
c). the symbol for velocity is .
You can use any symbol you want for velocity, as long as
you make its meaning very clear, so that everybody knows
what symbol you're using for velocity.
But this choice-c is still wrong, because either it's incomplete,
or else it's using 'space' for velocity, which is a very poor symbol.
d). to calculate velocity, divide the displacement by time.
Yes, that's OK, but you have to remember that the displacement
has a direction, and so does the velocity.

Explanation:
Answer:
Vapors
Explanation:
We take into account that all the energy from the lightning has been transformed into steam.
We calculate the amount of energy required by water to convert into steam.
From the lightning we received 
of energy, out of which 
has been used to convert the water into steam.
Energy left = 
We use this energy to convert steam into vapors.
With this temperature, we can easily interpret that the vapors will be dissociated in hydrogen and oxygen particles.
