<span>Volume Percent (volume/volume%) is defined to be the ratio of the volume of solute to the volume of solution times 100%.
The acetic acid is the solute volume. The bottle of vinegar is the solution volume.
Acetic acid (28.2ml) / Vinegar(165ml) x 100% = 17.1%</span>
Answer :- In a light wave the property of wave which tells about the color of light is it's Wavelength .
Wavelength is the distance between one crest and one through , also it is the distance after which the wave repeat itself !
It's SI unit is meter !
It is scalar quantity !!
Different Wavelength of light have different color !!
• VIBGYOR
i.e, Violent , Indigo , Blue , Green , Yellow Orange, and Red along with their shades are the colors which we can see !!
• They almost range from 400nm to 700nm ( visible range of light )
Answer:
D
Explanation:
We must study the reaction pictured in the question closely before we begin to attempt to answer the question.
Now, the reaction is a free radical reaction. This implies that only one electron is transferred. The transfer of one electron is shown using a half arrow rather than a full arrow. The both species are radicals (odd electron species) and contribute one electron each.
Hence we must show electron movements in both species using a half arrow.
Polyethylene is a type of plastic.
It takes 0.26 minutes to travel 1000 feet
<u>Solution:</u>
Given that car traveling at a constant speed travels 175 miles in four hours
Distance = 175 miles
Time taken = 4 hours
Convert the units to feet and minute
Given that,
1 mile = 5280 feet
175 miles = 5280 x 175 feet = 918720 feet
Also we know that,
1 hour = 60 minutes
4 hours = 60 x 4 minutes = 240 minutes
Thus, we got,
Distance = 918720 feet
Time taken = 240 minutes
<em><u>Find the speed of car</u></em>
<em><u>Speed is given by formula:</u></em>


Thus speed of car is 3828 feet per minute
<em><u>How many minutes will it take for the car to travel 1000 feet?</u></em>
Let "x" be the minutes needed for 1000 feet
speed of car is 3828 feet per minute
1 minute = 3828 feet
x minute = 1000 feet
This forms a proportion. We can solve by cross multiplying

Thus it takes 0.26 minutes to travel 1000 feet
