14. The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time
I hope I helped you with number 14, I can't answer number 15 sorry :(
All of the potential energy has changed and is being used in a different form. For example all of the potential energy could’ve change to kinetic energy. :)
Speed (velocity)=distance/time
V1=98km/4hr=24.5km/hr
V2=61km/3hr=20.3km/hr
Average speed (velocity)=total velocity/ number
Average speed (velocity)=44.8km/hr/2=22.4
So the average speed is 22.4km/hr

Answer:
- magnitude : 1635.43 m
- Angle: 130°28'20'' north of east
Explanation:
First, we will find the Cartesian Representation of the and vectors. We can do this, using the formula
where its the magnitude of the vector and θ the angle. For we have:
where the unit vector points east, and points north. Now, the will be:
Now, taking the sum:
This is
Now, for the magnitude, we just have to take its length:
For its angle, as the vector lays in the second quadrant, we can use:
