Answer:
10
Explanation:
Lets say that a,b,c,d,e are the five allowed energy states in order of decreasing energy. Then the number of possible different spectral lines comes from the electron dropping from a high state to a lower state. So, they will do so in following ways:
a - b
a - c
a - d
a- e
b - c
b - d
b- e
c - d
c- e
d- e
Ans- Ten different possible energy jumps giving six different colors or lines in the spectrum.
The change in velocity is +4 m/s to the right (or -4 m/s to the left).
The object's mass is irrelevant.

Answer:
The percentage error e% = Δm/m 100
Explanation:
The absolute error is the assessment with which measurements are made, it is given by the minimum reading value of a given instrument.
The accepted value is the value measured in an instrument. Or the one calculated by an experiment.
The percentage error is the ratio of the absolute error between the value of the average per 100
e% = Δm/m 100
