-- The frequency of an equinox is 2 per year.
-- The frequency of my sleeping really late is 1 per week.
-- The frequency of my intense desire to sleep late is 30 per month.
etc.
-- The standard unit of frequency in the SI system is "per second".
The special name for that unit is "Hertz". (Hz)
Answer:
The momentum principle tells us that impulse transfers momentum to an object. If an object has 2 kg m/s of momentum, a 1 kg m/s impulse delivered to the object increases its momentum to 3 kg m/s. That is, pfx = pix + Jx. Just as we did with energy, we can represent this “momentum accounting” with a momentum bar chart.
A hypothesis is a statement, not a question.so A
