Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus "anionic."
it allows u to know things and remember them when you need to. It also helps you recognize ur skills and allows you to be an easy problem solver when u know the concept because u did some research and know the answer to a question.
Explanation:
Answer:
The distance is
Explanation:
From the question we are told that
The wavelength of the light is
The distance between the slit is
The between the first and second dark fringes is
Generally fringe width is mathematically represented as
Where D is the distance of the slit to the screen
Hence
substituting values
Answer:c
Explanation:
Given
Object moving towards the motion detector at a constant speed
Constant speed indicates that there is no acceleration .
As the object is moving in a straight line therefore its velocity is same and do not changes with time
thus the correct option is c i.e. a straight line with zero slope.
