Answer:
it's because some versions have more steps and others have less
Answer
2) 1.5×10-2 m
Explanation
The potential difference is related to the electric field by:
(1)
where
is the potential difference
E is the electric field
d is the distance
We want to know the distance the detectors have to be placed in order to achieve an electric field of

when connected to a battery with potential difference

Solving the equation (1) for d, we find

Answer:
The minimum time to reach the target is 2156s
Explanation:
Check attachment
I believe the answer would be Light rays are reflected by mirrors
Answer:22537.92 J
Explanation:
Given
mass of karen 
Distance covered by Karen =69.6 m
acceleration due to gravity=9.8
inclination
vertically karen move

h=39.72 m
Work done by escalator on karen is equal to change in potential energy of karen
