As the axial tilt increases, then the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres. The northern hemisphere is tipped away from the Sun, producing short days and a low sun angle. What kind of effect does the earth's tilt and subsequent seasons have on our length of daylight (defined as sunrise to sunset). Over the equator, the answer is not much.

Answer:

Acceleration = 3 meter per second square

Explanation:

Acceleration (A) = rate of change in velocity

so,

=》A =

[tex] \frac{18 - 9}{3} [/tex]

Where time = 3 seconds

If 5 times a number is increased by 4 the result is 19 find the lest possible number that satisfies theses condition

Answers

Answer: 3

Explanation: 5 times a number would be 5x, then increase that by 4 is 5x+4.  The problem then says 5x + 4 ≥ 19.  If we solve for x then we get x ≥ 3 so x has to be greater than or equal to 3, so the smallest number it could be is 3.  You can even try any number smaller than 3 and see it doesn't work.  even something like 2.9

2. Katelyn is drinking a glass of tea. As the tea sits in the sun it begins to warm up. To
cool it back off again, she puts more ice in the glass.
After she puts ice in the glass, the ice tea cools down. What is occurring to the heat
in the glass?

Answers

AnswerB:

Explanation:

Heat can travel from one place to another in different ways. The different methods of heat transfer are conduction, convection and radiation. Here heat transfers from the glass to the ice through conduction.

What is conduction?

The process of transmission of energy from one particle of the medium to another with the particles being in direct contact with each other is defined as the conduction. It is also known as the thermal conduction or heat conduction.

In conduction an area of higher kinetic energy transfers thermal energy towards the lower kinetic energy area. Here a transfer of heat energy occurs from tea molecules to the ice cube. Due to the transfer of heat melting of ice occurs.

As the ice melts, the tea starts cooling while heating the ice cube. So the ice cools down the tea. The tea will be melted by the ice here.

Answer:

A. 0.48mol O2

Explanation:

The balanced equation is given as follows:

This shows that 2moles of CH3OH is required to react with 3 moles of O2

If 0.32 moles of CH3OH are reacted, then;

0.32 × 3/2 moles of O2 is required

= 0.96/2

Distance also affects the apparent brightness of an object. A distant, but very energetic star can appear dimmer to us than a lower-energy, but closer one. ...

(Pleaseeee help me) List 3 things you should talk about in a good conclusion?

Answers

1) It recaps where you’ve been.
Throughout your essay, you’ve shared experiences, skills and knowledge that have driven you toward who you are today. In your conclusion, remind the admissions team about how all those different elements work in combination to make you a unique candidate for their program.
2) It recaps where you are.
This is an aspect applicants often forget to include. You are at a crucial junction between the past and the future, and this program you’re applying to is the bridge. Recap why this program is an important stepping stone in your career path and how it’s a good fit for you personally.
3) It recaps where you are going.
Most importantly, you must tell the admissions team what your long-term career goal is. The more specific you can be, the better (even if you aren’t 100% sure, it’s best to come off as confident that you know what you want!). For example, rather than just recapping that you want to become a doctor, you can share additional sub-goals, such as wanting to be a doctor who works in low-income, inner city hospitals since you volunteered at those types of facilities before. Or perhaps you plan to go back to the country where you grew up and work as a surgeon there since they are in such short supply.
Bring It Together
Once we bring all three of those elements together, you can see how they link together to form one, solid conclusion. Ideally, your conclusion should be about 4-6 sentences long — not too short but not a long ramble. Below is an example showing how fusing the past (1), present (2) and future (3) together can end your essay on a strong note.

Las células epiteliales del estómago producen ácido clorhídrico HCI y su producción en exceso puede producir perforaciones en la mucosa. Una de las maneras de controlar dicho exceso es tomando una solución de bicarbonato de sodio NaHCO3, porque *

Answers

Answer and Explanation:

El bicarbonato de sodio (o carbonato ácico de sodio, NaHCO₃) es utilizado como antiácido debido a que neutraliza al ácido clorhídrico (HCl) en el estómago. Al ser disuelto en agua, el NaHCO₃ se disocia en iones como sigue:

NaHCO₃ → Na⁺ + HCO₃⁻

El anión bicarbonato (HCO₃₋) sufre hidrólisis, aceptando H⁺ del agua y  liberando iones hidroxilo (OH⁻):

HCO₃⁻ + H₂O → H₂CO₃ + OH⁻

Por lo tanto, la solución de NaHCO₃ es básica y sus aniones OH⁻ pueden neutralizar los H⁺ del HCl en el estómago, reduciendo la acidez.

describe the properties of the compound in sugar, and Compare the properties of the
compound with the properties of the elements that comprise sugar. How do you explain the difference?

Answers

Answer: Sodium chloride is an ionic solid, and when it dissolves in water, its individual sodium and chloride ions are dissociated from one another. Sugar molecules, on the other hand, maintain the bonds between their constituent atoms when dissolved, and thus remain as whole molecules in the solution.

Explanation: Here's why: Salt is about 25% more dense than sugar. Therefore a teaspoon of salt weighs more than a teaspoon of sugar by almost 25%. Your dissolving test would not be accurate because you would be starting out with a larger mass of salt than sugar.

Originally, the vast majority of peppered moths had light colouration, which effectively camouflaged them against the light-coloured trees and lichens upon which they rested. However, due to widespread pollution during the Industrial Revolution in England, many of the lichens died out, and the trees which peppered moths rested on became blackened by soot, causing most of the light- coloured moths to die off due to predation. At the same time, the dark-coloured moths flourished because of their ability to hide on the darkened trees.

Born to BikeWhen I moved to Canada, I was not familiar with riding a two wheeled bike.Riding a bike was like climbing mount Everest. Every time I would get on thebike I'd fall. It started off with wearing a helmet as my parents were holdingthe bike trying to balance it as I paddle. I kept on falling multiple times, and Iwould get mad at myself for not knowing how to bike. Especially since all thekids around me at the park already knew how to bike. It felt that I was a blotin the landscape. I continued to get up and face my problems by practicing onthe grass. When I began to practice on the grass, I fell a few times and wenthome muddy. After a couple of days of practicing, I was able to balance. Itwas a challenge for me to bike on the sidewalk because of all the injuries that Ipreviou got. Then I started to slowly alternate between the sidewalk andses. After two days of doing that, I was able to bike on the sidewalk. AsI continued to practice every single day, I became better and better and wasable to bike one handed. I started to bike far distance with my friends. I wasas free as a bird, going wherever I want and being with whoever, I want to bewith. We would bike for hours. Even when we got tired, our legs were sore, weneeded a break we kept on going. We were like little kittens that neverwanting to return home. Especially when we were far away from home andhave curfew. After knowing how to bike for a couple of years I was able to getthe bike that I always wanted. I was like the little kid who kept on checking upon it. I was able to buy accessories for it, like a lock and a basket and a waterbottle holder. I got to participate in several marathons. It looked as if we weremurmuring away. At the last marathon I participated at, I was able to achieveone of my biggest goals by placing third.
