Answer:
Solution:
As per the question:
Point charge, q = 
Test charge, 
Work done by the electric force, 
Now,
We know that the electric potential at a point is given by:
where
r = separation distance between the charges.
Also,
The work done by the electric force i moving a test charge from point A to B in an electric field:
Answer:
Time use of cellphone times 3 hours before sleep.
Explanation:
It is scientifically proven that cell-phone use before bed can disturb your sleep. The blue light can cause your brain to release chemicals that associate with staying awake or even waking up. So measure the hours or minutes you use your phone 3 hours before you go to sleep.
Answer:
Increase in the intensity of pressure allows very less deformation
Explanation:
For the water the variation of pressure at any depth is directly proportional to the depth of the water above that level.
Thus, at depth greater than 60 m the intensity of pressure on ice is very high and therefore very little deformation is possible.
Hence, the transition from brittle to ductile behavior is observed.
Answer:
The lightbulb will not turn on because a switch is connected to it in parallel and when it is closed, like it is now, it becomes a short, by-passing the bulb completely.
