Answer:
The answer is : Yes
Explanation:
because it 12:00 and the storm is moving at 25km/hr and it 75 km away that means in three hours the storm would hit your town so at 3:00 the storm would hit at your at ends at 2:00 so yes you would get home before he storm hit.
Answer:
Accuracy
Explanation:
Accuracy is the nearness of measurement to true value.
Precision deals with the ability to be able to reproduce a set of result.
In calculating percentage error, we simply find the difference between the approximately measured value and the true value. We then divide by the true value and express as a percentage.
This percentage shows how much error was incurred in our expriment which did not yield the true value. An accurate result has a low percentage error.
Answer:
120.575 kJ is the activation energy for the souring process.
Explanation:
The formula for an activation energy is given as:
where,
= rate constant at =
= rate constant at =
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
= initial temperature =
= final temperature =
Now put all the given values in this formula, we get:l
120.575 kJ is the activation energy for the souring process.
