Answer:
Breaths per minute is a frequency. The period is its reciprocal.
Explanation:
In simple harmonic motion, a period (T) is the time taken for one point to start in a position and reach that position again, in other words to complete a cycle or lapse. In this case, a period is the time one takes from starting to inspire the air to releasing all of it from the lungs.
In simple harmonic motion, the frequency (f) is how many times a point completes a cycle or lapse in one unity of time (could be one second, one minute, one hour, etc). In this case, the frequency is how many times one breathes in one minute. This is the breathing rate, since it is breathings per minute. Breaths per minute is a frequency.
Period (T) and frequency (f) relate to each other in the following formulae: 
or 
.
Therefore, breaths per minute is a frequency, and since it is related to the period, we say the period is reciprocal to it.
Answer:
Part a)
Part b)
direction = downwards
Explanation:
As we know that the negative charge will experience the force due to some other charge below it
the force is given as
now we know that
now plug in all data
since this is a repulsion force so it must be a negative charge
Part b)
As per Newton's III law it will exert equal and opposite force on it
So here the force on the charge below it will be same in magnitude but opposite in direction
so here we have
direction = downwards
Answer: C. The tendency of an object to maintain its state of motion.
Explanation: Newton’s first law: If a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Parallel universe, or alternate reality, is a hypothetical self-contained plane of existence, co-existing with one's own
