All of these steps are useful towards getting a job.
Answer:
Explanation:
From the given information:
The elastic potential energy can be calculated by using the formula:
Making K the subject;
k = 2.3 × 10⁻² N/m
Now; the frequency of the small oscillation can be determined by using the formula:
where;
m = mass of each atom = 1.66 × 10⁻²⁶ kg

Answer:
c. As we gain mass, the force of gravity on us increases
Answer: relative motion between observer and the sound source.
Explanation: The Doppler effect states that when there is a relative motion between an observer and a sound source the frequency of sound perceived by the observer is different in frequency from the original from the source.
The mathematical back up for this claim is given below.
f' = (v+v') /(v-vs) × f
Where f' = observed frequency
v = speed of sound in air
v' = velocity of observer
vs = velocity of source
f = frequency of sound source.
From the formulae, it can be seen that a change in the value of the velocity of observer (v') and source (vs) produces different value of observed frequency (f').
Note, frequency of sound (f) is a constant.
