For any question related to newons law of motion first draw the free body diagram(FBD),
Answer:

Explanation:
If we have a net force F acting on a body of mass m it will experiment an acceleration a. Newton's 2nd Law gives us the relation between these quantities: F=ma.
In our case, we want to calculate the acceleration, so we write:

With the values we have we get:

Answer:
2 m/s
Explanation:
Given that a student walks 4 blocks east, 1 blocks north, 2 block west and then 1 blocks south in an hour.
The total time = 1 hour
The vertical displacement = 1 - 1
Vertical displacement = 0
Horizontal displacement = 4 - 2
Horizontal displacement = 2
Total displacement = sqrt (2^2 - 0^2)
Total Displacement = 2
Average velocity = displacement/time
average velocity = 2 / 1
Average velocity = 2 m/s
Therefore, her average velocity is 2 metres per second.
The, it's electron goes for HIGHER orbital form lower orbital

Our Atmosphere is full of freely subtended particles, and when light from sun strikes the particles then scattering occurs, in which blue colour is most scattered and hence causing Sky to appear blue .
Hope it helps !!
