"Electrostatic forces are attractive or repulsive forces between particles that are caused by their electric charges."

Explanation:
this is an example of a question that cannot be solved or why do we sleep too cannot be solved
Calculating acceleration involves dividing velocity by time — or in terms of units, dividing meters per second [m/s] by second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared.
This I what it showed when I looked it up so if your writing this down try and put some in your own words
Answer:
Average speed will be 48.23 km/h
Explanation:
Let the distance up to hill is = d km
Speed when car goes to hill = 38 km/h
So time required
Speed when car return from hill = 66 km/h
So time required to return fro hill
Total time
Total distance = d+d =2d
So average speed
