suppose dan drives his car 350 miles North from Crystal city to blue lake in 8 hours What is the total velocity
1 answer:
Consideing the definition of velocity, the total velocity is 43.75 miles/h.
<h3>Definition of velocity</h3>Velocity is a physical magnitude that relates the displacement of an object, the time it takes to make this change in position and direction.
The velocity can be defined as the amount of space traveled per unit of time with which a body moves, considering the direction, and can be calculated using the expression:
velocity= distance traveled÷ time
Velocity has units of .
In this case, you know:
- distance traveled= 350 miles
- time= 8 h
Replacing in the definition of velocity:
velocity= 350 miles÷ 8 h
Solving:
<u><em>velocity= 43.75 miles/h</em></u>
Finally, the total velocity is 43.75 miles/h.

Answer:-ΔG=-101.5KJ
Explanation:We have to calculate ΔG for the reaction so using the formula given in the equation we can calculate the \Delta G for the reaction.
We need to convert the unit ofΔS in terms of KJ/Kelvin as its value is given in terms of J/Kelvin
Also we need to convert the temperature in Kelvin as it is given in degree celsius.
After calculating forΔG we found that the value ofΔG is negative and its value is -101.74KJ
For a reaction to be spontaneous the value of \Delta G \ must be negative .
As the ΔG for the given reaction is is negative so the reaction will be spontaneous in nature.
In this reaction since the entropy of reaction is positive and hence when we increase the temperature term then the overall term TΔS would become more positive and hence the value of ΔG would be less negative .
Hence the value of ΔG would become more positive with the increase in temperature.
So we found the value of ΔG to be -101.74KJ
