Answer:
a) 17.49 seconds
b) 13.12 seconds
c) 2.99 m/s²
Explanation:
a) Acceleration = a = 1.35 m/s²
Final velocity = v = 85 km/h =
Initial velocity = u = 0
Equation of motion
Time taken to accelerate to top speed is 17.49 seconds.
b) Acceleration = a = -1.8 m/s²
Initial velocity = u = 23.61\ m/s
Final velocity = v = 0
Time taken to stop the train from top speed is 13.12 seconds
c) Initial velocity = u = 23.61 m/s
Time taken = t = 7.9 s
Final velocity = v = 0
Emergency acceleration is 2.99 m/s² (magnitude)
Answer and Explanation:
The computation of the shortest wavelength in the series is shown below:-
Where
represents wavelength
R represents Rydberg's constant
represents Final energy states
and represents initial energy states
Now Substitute is
now we will put the values into the above formula
Now we will rewrite the answer in the term of
So, the whole Paschen series is in the part of the spectrum.
