For the writer, scientific models are paradigms of set of patterns that is assumed to happen in a particular situation or circumstance which is why it was created and modeled, to explain a certain phenomenon. Take for instance the biogeochemical cycle model –water cycle. The water cycle model involves the different process which was observed happen as the current cycle has been experimented and predicted to happen again with the same process. <span>
</span>Models can represent things that are too small to see. <span> Scientists rely on models to represent concepts and processes in physical science because models can represent things that are too small to see. In fact, they are actually used to give a better perspective of what is occurring on these hidden to the naked eye matters –which may include atoms, cells, and entities unseen and latent. It gives scientists the ideas and structure, restructure, integrate and ponder on new hypothesis on these matters. <span> </span></span>
There are several formulas that describe the distance, speed, and time for
a falling body. The one I use the most happens to be the one that'll be the
most useful to solve this problem:
Distance = 1/2 g t²
We know the distance and we know ' g ', so we can use
this formula to find ' t '.
Distance = (1/2) (gravity) (time)²
(239 m) = (1/2) (3.7 m/s²) (time)²
Divide each side
by 1.85 m/s² : (129 m) / (1.85 m/s²) = (time)²
(129/1.85) sec² = (time)²
Take the square root
of each side: 8.35 sec = time
Answer:
0.1 m
Explanation:
The closest distance the electrodes used in an NCV test in oerder to measure
the voltage change as a response to the stimulus is 0.1 m.
This is because the shortest observable time period is not less than the action-potential time response of 1 mili second the length traveled by the sensation during this time is 1 m sec x 100 m / s =0.1 m, which is the shortest distance the electrodes could be positioned on the nerve.
<span>Magnetic field 'lines' were invented by people, to have a visualization of the
magnetic field. We draw 'lines' to show the direction of the force that a tiny
test magnet would feel if it were at any point in the field, and the direction
it would move from there.
If 'lines' crossed, then there would be a point in the field where a tiny test
magnetic would feel a force in two different directions, and it would have a
choice of which way to go from there. That doesn't happen.</span>
Answer:
v1=18.46m/s
v2=29.8cm/s
Explanation:
We know that
the equation of the motion is
we can calculate w by using
Hence, we have that
the speed will be
hope this helps!
