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.

Answers

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.

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

The formula of the ionic compound is X₃Y₂.

The relationship between kinetic energy and speed is

Answers

Answer:

The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.

This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.

KE = 0.5 • m • v2

where m = mass of object

v = speed of object

That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.

How much energy does a wave with a frequency of 7.0 x 1012 Hz have

Answers

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) =

Answers

Answer:

Las reacciones de adición son... 2 reactivos producen un solo producto.

Explanation:

Las reacciones de síntesis o combinación ocurren cuando dos o más reactivos forman un solo producto; generalmente se libera calor, siendo reacción exotérmica. También se les conoce como reacciones de adición.

En otras palabras, las reacciones de adición son aquellas en las cuales todos los átomos de los reactivos van a formar parte  de un único producto. Uno de los reactivos (al que se le suele llamar sustrato)  debe contener un enlace doble, o uno triple. Las Reacciones de Adición se dan principalmente en Química Orgánica donde los dobles y triples enlaces son comunes.

La característica principal de estas reacciones es que durante el proceso, el doble o triple enlace se rompe formando nuevos enlaces.

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here element barium is having an oxidation state of +2 called as [tex]Ba^{2+}[/tex] cation and [tex]O^{2-}[/tex] is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral [tex]BaO[/tex]
