Is potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system
Answer:
1.3 m/s
Explanation:
average speed = total distance/ total time
Answer:
A) for leftmost point the coordinate is -0.28m that means it should be 0.28m towards the right.
B) for rightmost case the coordinate is 0.28m which is where komila should sit.
Explanation:
Detailed calculation and explanation is shown in the image below
It is converted to kinetic energy.
Answer:
The correct answer is "22.27 hours".
Explanation:
Given that:
Radioactive isotope activity,
= 490,000 Bq
Activity,
= 110,000 Bq
Time,
= 48 hours
As we know,
⇒ 
or,
