Answer:
Velocity = 15.87m/s
Explanation:
Given the following data;
Distance, d = 200000m
Time, t = 12600secs
*To find the velocity*
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
![Velocity = \frac{distance}{time}](https://tex.z-dn.net/?f=Velocity%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
Substituting into the equation, we have;
![V = \frac{200000}{12600}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B200000%7D%7B12600%7D)
Velocity = 15.87m/s
<em>Therefore, the velocity of the car is 15.87 meters per seconds due west.</em>
It also takes energy to break the hydrogen bonds in water that must be disrupted to insert one of these sucrose molecules into solution. Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.
