Answer:
0.00000011 m
Explanation:
n = 0 for minimum thickness
t = Thickness
= Refractive index of the film = 1.25
= Wavelength =
We have the formula
The minimum thickness of the film is 0.00000011 m
Answer:
1.49 m/s
Explanation:
The average speed is:
Where v is speed, s is distance and t is time. We are given with a distance of 18 km and time is 3.36 hours.
We'll be converting from km to meters and hours to seconds as standard unit for speed is m/s.
To convert the unit from kilometer to meter, we know that 1 kilometer equals to 1000 meters. Therefore, 18 kilometers will equal to 1000 * 18 meters which will equal to 18000 meters total.
To convert from hour to second, we know that 1 hour equals to 60 minutes. Therefore, 3.36 hours will equal to 60 * 3.36 = 201.6 minutes.
A minute equals to 60 seconds. Therefore, 201.6 minutes equal to 60 * 201.6 = 12096 seconds.
Finally, we have units in meter and second. We'll be able to calculate for average speed now by applying the formula above:
Therefore, Serina's average speed will be around 1.49 m/s
Answer:
Explanation:
<em>Diesel engines burn as much as 30% less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming.
</em>
<em>
</em>
<em>
</em>
<em>(A) of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have
</em>
<em>
</em>
<em>(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gasses having

<em>
</em>
<em>(C) of comparable size, and also they emit far fewer carbon dioxide and other gasses that have

<em>
</em>
<em>(D) that have a comparable size, and also they emit far fewer of the other gasses having
</em>
<em>
</em>
<em>(E) that have a comparable size, as well as emitting far fewer of the other gasses having</em>
<em>A is the most appropriate statement above. Diesel engine consume less energy and release fewer gases than the gasoline engines .</em>
<em>Both engine(Diesel and gasoline) converts chemical energy to electrical energy.</em>
