Electrons in excited hydrogen atoms are in the
Sidana [21]
I can see three different transitions here:

3 --> 1

3 --> 2
followed by
2 --> 1 .

So we should expect to see three different 'colors'
being emitted from this excited mob.

A high-speed ""bullet"" train accelerates and decelerates at the rate 4 ft/s 2 . Its maximum cruising speed is 90 mi/hr. (a) Wha
NemiM [27]

Answer:

23 mi

Explanation:

Let us first record all the values we have

acceleration = 4 ft/s

max speed = 90 mi/hr * 1 hr/3600s * 5280 ft/1 mi = 132 ft/s

We can use the equation of linear motion since acceleration is constant

distance covered = distance during acceleration + distance during costant

                                 velocity

s = \frac{v_{f} ^{2} - v_{i} ^{2}  }{2a}  + v_{i}t\\\\s = \frac{132 ^{2} - 0^{2}  }{2*4}  + 132*900\\s = 120 978ft

distance in miles = 120 978 ft * 1 mi/5280 ft = 22.9125 mi ≈ 23 mi
