For the given question above, there are other details that is missing. Here is what I got from my research.
Mass of a hydrogen atom as 1.008 u,
<span>where 1 u=1.661 times 10^-27 kg.
</span>The frequency of a mass on a spring is:
<span>f = omega / 2pi = sqrt (k/meff) / 2pi </span>
<span>The meff you use is the effective mass. If two bodies with mass M and m are both free to move: </span>
<span>Meff = Mm / (M+m) </span>
<span>If M=m, then Meff = m/2 (as you were given) </span>
<span>So the answer is: </span>
<span>f = sqrt (2k/m) / 2pi </span>
(d) is increasing its velocity by 2.0 m/s every second.
An acceleration of 2 m/s² means that the object is is increasing its velocity by 2.0 m/s every second.
<h3>What is an acceleration?</h3>
The rate at which an object's velocity changes over a predetermined period of time is referred to as its acceleration. Acceleration is mathematically defined as an object's change in velocity divided by the amount of time it took for that change to occur.
The positive sign of the acceleration denotes a change in velocity that is positive and growing, whereas the negative sign denotes a change in velocity that is decreasing.
Consequently, an acceleration of 2 m/s² indicates that the object's velocity is increasing by 2 m/s every second.

Answer:
electrons
Explanation:
You might mean an "oxidation-reduction" reaction, also known as a redox reaction, in which electrons are transferred between chemicals (i.e. the oxidation number changes).
An "oxygen-reduction" reaction is a very specific reaction where oxygen gas is reduced to water or hydrogen peroxide.
Answer:
2m/s
Explanation:
Total Distance = 300m+200m = 500m
Total Time = 100s+150s = 250s
Average Speed = Total distance travelled/Total time taken
=500m/250s
=2m/s
