Matter> anything that has mass and takes up space.
Then it’s pure substances (goes on right) then definition is the one that is, “matter that only has 1 set of chemical and physical properties” > divides into compounds and elements. The detention of compounds is, contains two or more elements chemically bonded together.
Oxygen, is under elements.
Then on the left goes mixture; definition, “
Under compounds goes sodium, co2, h2o
under it goes homogeneous (left) def: “more than 1 type of matter that looks different through” and heterogeneous (right Im sure). Def. of heter is, “two or more substances chemically combined and can be separated.”
Under heter goes; soil and blood
Under homo: kool aid,
Chex mix and cake batter
That’s what I’ve gotten so far
It's shows static electricity because of the hair
Answer:
a what’s happening in the atmosphere at a given place and time
The universal gravity formula is <span>F = G(Me)(Mm)/r^2. Lets use this formula to help us calculate what would happen if the Moon was twice as big.
</span><span>Mn = new mass = 2*Mm
</span><span>Fn = G(Me)(Mn)/r^2
</span><span>Fn = G(Me)(2Mm)/r^2
</span>Fn = 2*G(Me)(Mm)/r^2
<span>Fn = 2*F
</span>So 2 times the force it was before. The force should be the same, but you never know the moon and space as well know it can work in very mysterious ways.
Answer:
1.47 J/kg
120 m
Explanation:
The maximum height it can jump in a single leap 15 cm, = 0.15 m
to get the kinetic energy per kg of mass, we need to find the takeoff speed. The take off speed can be calculated by using the formula
v =
where h = 0.15
v =
v =
v = 1.715 m/s
energy per kg of mass =
1/2 * (1.715) = 1.47 J/Kg
TJe height a human can jump when compared to the flea is
2 m/2.5 mm * 15 cm =
2/0.0025 *0.15 =
800 * 0.15 = 120 m
