Answer:
0.6m/s²
Explanation:
Given parameters:
Initial velocity = 3m/s
Final velocity = 4.5m/s
Time taken = 2.4s
Unknown:
Average acceleration = ?
Solution:
To solve this problem, we use the expression:
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Acceleration = = 0.6m/s²

Answer:
c.Therefore, we can say that the energy difference between adjacent orbit radii decreases with increasing values of the principal quantum number.
Explanation:
For the adjacent orbits or orbits that are one above the other
change in energy is given by
ΔE =
where n= orbital number
so ,
now , if n value is increased,
value [ 1/(n)^2 - 1/(n+1)^2 ] will go on decreasing by clear observation as n is in the denominator
Therefore, The energy difference between adjacent orbit radii decreases with increasing values of the principal quantum number.
