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.

Which statement is true about heat transfer? *
5 points
a. Heat can only transfer when touching another object.
b. Heat always travels up.
c. Heat transfers from cooler to warmer objects.
d. Heat transfers from hotter to cooler objects.
Answer: A
Explanation:
heat always passes from a warmer object to a cooler object until all objects are the same temperature. Conduction is how heat travels between objects that are touching. Conduction travels fastest through solids, but liquids and gases can also conduct heat.
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 =
4.638249028 × 10⁻²¹ J/s ≈
4.64 × 10⁻²¹ J/s
HEYOO PEEPS 1. Ethan Rides his bike up a 20km hill in 2hrs. Ethan rides his bike down the 20km hill in .5 hrs. What is Ethan’s average speed?
Answer:
let Leo's speed = x mile/hr
so Ethan speed = (x + 6) miles per hour
Distance = Speed × Time
so distance traveled by Leo in 2 hours = x × 2 = 2x
and distance traveled by Ethan in 1.5 hours = 1.5( x + 6 ) = 1.5x + 9
since they meet on the path , After Ethan has ridden 1.5 hours and Leo has ridden 2 hours , so together the have traveled on complete path that is 65 miles.
⇒ distance traveled by leo in 2 hours + distance traveled by Ethan in 1.5 hours = 65
⇒ 2x + 1.5x + 9 = 65
⇒ 3.5x = 56
⇒ x = 16
Hence Leo's speed = x miles/hr = 16 miles/hour
and Ethan's speed = (x + 6) miles/hr = 16 +6 = 22 mile/hour

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.

The poisonous gas hydrogen sulfide, H2S, can be neutralized with a base such as sodium hydroxide,
NaOH. The unbalanced equation for this reaction follows:
NaOH(aq) + H25(e) → Na2S(aq) + H2O(1)
A student who was asked to balance this equation wrote the following:
Na2OH(aq) + H2S(g) → Na2S(aq) + H2O(
Is this equation balanced? Is it correct? Explain why or why not, and supply the correct balanced
equation if necessary.
Answer:
It's not correct. For balancing, we need to put the coefficients in the molecule, not in the athom. Because if you do this, you're creating another molecule, instead of a balacing, for which the reaction may not happen - but anyway, it would be another reaction.
The correct balacing is:
2NaOH + 1H2S → 1Na2S + 2H2O
Explanation:
Look: Na2OH does not even exist. OH has only one free link, so he can't - in normal conditions - make another one with any athom. That's why we should write 2NaOH instead of Na2OH. The first means "2 mols of NaOH".

Calculate the molar volume (volume of 1.0 mole) of an ideal gas at 1.0 atm and 25 °C?
Answer:
24.47 L
Explanation:
Using the general gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = 0.0821 Latm/molK
T = temperature (K)
According to the provided information in this question,
P = 1.0 atm
V = ?
n = 1 mol
T = 25°C = 25 + 273 = 298K
Using PV = nRT
V = nRT ÷ P
V = 1 × 0.0821 × 298 ÷ 1
V = 24.465 ÷ 1
V = 24.465
V = 24.47 L

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

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
