Drag Forces and Friction
What happen when there is more velocity?
As result is more draging force
Can distance traveled have negative sign?
No.
The motion of an object can be represented by...
a position-time graph.
What is the fromula to calculate the weight?
W = mg
Which is the difference between a moth and a butterfly?
The first difference between a moth and a butterfly is th postion of its wings. The butterlflies have them up, and the moths have them in the back.
But this can vary, it depends in the specie.
Also another difference is tht the moths don't need to eat. They eat al they need for their life when they are a little worm.
But is also can vary
And the last and pricipal difference is that the moths are the "butterflies of the nigh". So the moths only appear in the night and the butterflies in the day, but as usual, this can vary.
Solve the following equation
9c + 1 = 10
c = 1
What is displacement?
The change of position of an object
In a position-time graph, x means...
time
What is mass?
the amount of "stuff" of something
Why aren't the fungi part of the plantae kingdom?
The fungi aren't vegatables, because they don't do the photosynthesis from chlorophyll, like the plants do. They do the digestion of organic material, by degarding it with some especial enzymes. Once they digest it, they ingest and finally absorb it
Solve the following equation
m/5 + 9 = 11
m = 10
What is distance traveled?
The total leght of the point traveled between two positions
In a position-time graph, y means...
position relative to the starting point
State 3 Contact Forces
Applied Force, Normal Force, Friction, Tension, Air Resistance
Whish is the difference between an Eukaryotic and a Prokaryotic cell?
The first difference is that the eukaryotic cell is for plants and animals, but the prokaryotic is for other organisims like bacterias and virus.
In the prokaryotic cells there is no Lysosomes and Peroxisomes and in the eucaryotic cells there are present. Also in the prokaryotic cell the microtubules are absent and in the eukaryotic no.
Endoplastic reticulum is present in a eukaryotic cell, and in the prokaryoitic no
And for last, the eukryotic cells are multicellular and the prokaryotic are unicellular.
Name 3 things that increases the drag force
non-steamined shapes, moving fast, large-cross selection, rough surfaces, moving in liquid.
What is the displacement formula?
Δx =xf −x0
If the motion is constant positive velocity results in...
line of constant & positive slope
What is a field?
a special region where something experiences a force
Which is the biggest orgnism in the Earth?
The biggest organism in the Earth, is a fungus in the forests of Oregon. Its micelium is around 1,800 futball grounds of length.
(Remember the mycelium is the part of the fungus that is inside the land, and the mushrooms are the visible part, that contains the spores to continue with the reproduction of the fungus).
Name 3 things that reduce the drag force
smooth surfaces, strealined shape, moving slow, small-cross selection, lubrication.
Displacement is a vector, so this means...
has a direction as well as a magnitude.
If an object is accelerate and have positive velocity results in...
in a curve line in the positive part of the graph.
As you get further away from the mass, the magnet or charge...
the fields get weaker
Are myriapods insects?
Which animals belong to this group?
The first answer is no, the myriapods aren't insects, there are many characters that mark a difference between this two.
Animals that belong to the chilopoda class, like animals from the Scolopendridae family,centipede, millipede, etc. Belong to this class. This class is identificated because most of its members, have poison in the pair closest to the head. This subphylum counts with more than 16,000 species.
