<span>The atomic weight of silver is 107.8682</span>
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
This info tells us if it stable or not and it tells us how many electrons it need to be stable.
Answer: Option (d) is the correct answer
Explanation:
The energy present within the bonds of the atoms of a compound or molecule is known as chemical energy.
As this energy is present at a position that is, within the bonds hence it is a potential energy. So, whenever there occurs a chemical reaction the stored chemical energy is released.
As potential energy is the energy possessed because of position of a substance. And, kinetic energy is the energy present due to the motion of an object.
Therefore, we can conclude that chemical energy is a form of potential energy.
