Answer;
= 90600 m/s...
Explanation;
velocity of ball = 96 mi/hr = 42.916 m/s...
velocity of bat = -56mi/hr = -25.034m/s.. ( note the negativity here..)
time = 0.75 millisec = 0.75 * 10^-3 sec
acceleration = (velball - velbat) / time
= (42.916 - (-25.034)) / (0.75 * 10^-3)
=90600 m/s
Answer:
See the explanation below.
Explanation:
A species is invasive can be spread, naturally either by the behavior of the species, or introduced accidentally or voluntarily by man.
The invasive species increases its density in the occupied area or colonizes new territories over time.
That an invasive species is harmful means that it produces significant changes in the composition, structure or processes of natural or semi-natural ecosystems, endangering native biological diversity.
Uncontrolled reproduction of this invasive species also increases the risk of control and extermination of the species, due to the acclimatization of the new species in the environment as well as possible exponential reproduction.
I think it’s D but i’m not too sure
The frequency is how many per second:
(6 swings)/(30 sec) = (6/30) swing/sec = 0.2 per sec = 0.2 Hz .
The period is how long each one takes, or seconds per swing.
It's exactly the flip of frequency.
So we could just take the frequency, flip it, and find 1 / 0.2 ,
but let's do it the long way:
(30 sec) / (6 swings) = (30/6) sec/swing = 5 seconds .
