Answer:
toda
Explanation:
:todo lo que tienes que hacer es hacer la cosa
Answer:
16.6km/h
Explanation:
Speed is distance/time.
speed for 1st event = 1/0.4 = 2.5km/h
speed for 2nd event = 50/1.5 = 33.3 km/h
speed for 3rd event = 10/0.7 = 14.28 km/h
Average speed = 2.5 + 33.3 + 14.28 /3 = 50/3 = 16.6 km/h

write an Argument for people of westfield identifying the reddish brown substance. Plz answer this is due tomorrow!!
Answer:
The reddish-brown substance is a different color than the fertilizer, which is white, and the substance that makes up the pipe, which is gray. This means that they cannot be the same substance because they do not have the same properties. The atomic models show that the reddish-brown substance is made up of different repeating groups of atoms than the fertilizer and the pipe substance. The difference in atoms caused the difference in properties.
Explanation:
lul
People of westfield identifying the reddish brown substance and that substance is rust i.e. iron oxide.
What is rust?Rust is a chemical compound which is formed by the oxidation reaction between iron and oxygen for the formation of iron oxide.
People of westfield observed the reddish brown color in the water, that is the rust compound which is obtained by the chemical reaction occur between the iron pipes and the compound present in the fertilizers that are present in water.

You live near the ocean and your friend lives further inland. Based on this, what can you say is most likely different about the climate in your area from your friend's area in the winter?
Your friend has colder winters than you do.
Your friend has warmer winters than you do.
You have less precipitation than your friend does.
You get more sunshine in the winter.
Answer:
I'm thinking its "Your friend had colder winters than you do."
Explanation:
It is not "Your friend has warmer winters than you do." Or "You Have less precipitation than your friend does." I was doing this quiz before that had this question and its not those.
In the ocean side the the winter will be colder by the ocean breeze in the day time. The location of your friend farther from the ocean will have warmer winters than you.
What is sea breeze ?Any wind that flows from a big body of water onto or onto a landmass is called a sea breeze or an onshore breeze. Sea breezes form as a result of changes in air pressure brought on by the different heat capacities of water and dry land. Sea breezes are therefore more confined than prevailing winds.
A sea breeze is frequently seen along coasts after sunrise because land warms up far more quickly than water does when exposed to solar radiation. While dry ground also cools faster than water, a land breeze or offshore breeze has the opposite effect.
In winter seasons, along with the sea breeze make the climate more colder than that in locations farther from oceans. Hence, option b is correct.

How much energy does a wave with a frequency of 7.0 x 1012 Hz have
Answer:
4.64 × 10⁻²¹ J/s
Explanation:
[Only if the wave travels at the speed of light]
Because a wave presumed to be at light speed is a photon, E = hf.
If frequency is not given, E = hc/λ
c is the speed of light in meters per second. c = 299, 792, 458 m/s.
λ is the wavelength which is dependent.
h or plancks constant = 6.62607004 × 10⁻³² m² kg / s.
E is in units of J / s or jules ( m² kg ) per second.
If the wave has a frequency of 7.0 x 10¹² Hz or 7 THz (Tera-Hertz).
E = (6.62607004 × 10⁻³⁴) × (7.0 × 10¹²) =
46.38249028 × 10⁻²² =

Answer:
We can tell by how the continents look. Scientists who propose the pangea theory have said this. You can see for yourself because all the continents look like puzzle pieces you could put together. Scientists can also tell from the species. For example, let's say a scientist found a bone of a creature at the edge of a continent, the edge of another would have the same species. They have also calculated that the continents in itself are still splitting apart, but very slowly. The reason they split up was because tectonic plate movements.

Answer:
If I am not wrong is C x2y5
Explanation:
The concept of valency is used here to determine the formula of the ionic compounds. The number of valence electrons in 'X' is 2 and that of 'Y' is 5. The formula is X₃Y₂. The correct option is D.
What is an ionic compound?The crystalline solids which are formed by neatly packed ions of opposite charges are defined as the ionic compounds. These compounds are formed by the combination of metals with non-metals.
The combining capacity of an element is given by valency. The elements belonging to the same group have the same valency. It is related to how many electrons are in the outer shell.
Here the number of valence electrons in 'X' = 2
The number of valence electrons in 'Y' = 5
The element 'X' need 6 electrons to attain the octet and 'Y' needs 3 electrons to attain the octet.
X - 6
Y - 3
