Multiplied by; speed = distance x time
Answer:
The electric force on the top charge is .
Explanation:
Given that,
Electric charges in a thundercloud,
The distance between charges, d = 2.3 km = 2300 m
Let F is the electric force on the top charge. The electric force is given by the formula as :
or
So, the electric force on the top charge is . Hence, this is the required solution.
Answer:
Norma’s average speed is 41.9 km/h.
Explanation:
The average speed is given by:
Where:
: is the total distance
: is the total time
We can find the total distance as follows:
Now, the total time is:
Hence, the average speed is:
Therefore, Norma’s average speed is 41.9 km/h.
I hope it helps you!
Distance= Speed x Time Distance= 1.9m/s x 3.5h= 6.5km
I think this is right and I hope this helped you! :)
