Answer:
The electrical potential energy is 0.027 Joules.
Explanation:
The values from the question are
charge (q) = 
Electric Field strength (E) = 
Distance from source (d) = 0.030 m
Now the formula for the electrical potential energy (U) is given by

So now insert the values to find the answer

On further solving

Three things that effect a life system would be
- sunlight
-water
-energy/food
Hope this helps
Answer:
Yes
Explanation:
