Answer: A Meteor
Explanation:
A streak of light in the sky and says she is seeing a shooting star. She's most likely observing is a meteor. Therefore, option C is correct.
What is a meteor ?A meteor is an object from space or a meteoroid that touches down on Earth. The air on the space rock creates drag that causes it to become incredibly heated as it falls toward Earth.
When the earth travels through cometary debris during its orbit around the Sun, meteor showers will result. Although the Earth's orbit around the Sun is nearly round, the majority of comets have very elliptical orbits.
A meteoroid becomes a meteor, or a streak of light in the sky, if it gets close enough to Earth and enters its atmosphere. These light striations are sometimes referred to as "shooting stars" due to their appearance. However, stars are not what meteors are.
Thus, option C is correct.

A student redid the experiment of mixing room-temperature water and warm
water. This time, she doubled the amount of room temp water. How will the final
temperature be different?
A- It will be higher, because the amount of water in the mixture is greater.
B-It will be lower, because the temperature of the room-temperature water will not increase as much.
C-It will be the same because all parts of the mixture will end up at the same temperature.
D-It will be higher, because all parts of the mixture will end up at the same temperature.
Answer:
B) It will be lower, because the temperature of the room-temperature water will not increase as much.

You are out on a hike, and you notice that the line of telephone wires you have been following along a slope is crooked. Two of the posts are much farther down slope then the others. What has likely occurred on this hillside?
Answer:
The awnser is creep
Explanation:
There don't appear to be any dial tone problems on the telephone caused by broken wires, connectors, wall jacks, or other network-interfering hardware.
What is hardware ?Hardware describes the physical parts of the computer or its delivery mechanisms for the software's written instructions to be stored and executed. The device's intangible component that enables user interaction with the hardware is called the software.
Software is referred to as "soft" because it is flexible, but hardware is referred to as "hard" because it is rigid in terms of modifications. Software often instructs hardware to carry out any command.
Since a smartphone is fundamentally a small computer, it has several parts in common with computers, such as processors and memory. It's critical to balance your demands on this hardware because these components are continuously improved in new phone generations.
Thus, It doesn't seem that any broken wires, connectors, wall jacks, or other network-interfering gear are the root of any dial tone issues on the hardware.

A meteorologist uses a weather map to explain an upcoming change in weather. The map shows a blue line with triangles approaching a red line with semicircles. Based on the map, which weather prediction is most valid? (1 point) A a significant drop in temperature will occur across the area. B There is no chance of precipitation in the forecast. C Warm temperatures will replace cold temperatures. D Humidity levels will rise.
Answer:
Option C: Warm temperatures will replace cold temperatures.
Explanation:
In a weather map, a warm front is depicted with a red line and red semi circles while a cold front is depicted with a blue line and blue triangles.
Now, we are told that the map shows a blue line with triangles approaching a red line with semi-circles. This means that the cold front is approaching the warm front.
Now a warm front is simply defined as the transition zone where warm air mass gradually replaces a cold air.
Thus, it means the weather map depicts the fact that warm temperature is replacing cold temperature.
Thus; Option C is correct.
Answer: 1: A cold front moved into the area. 2: It would actually be A. A significant drop in temperature will occur across the area. 3: Movement of large air masses. 4: “A Strong Cold Front Threatens the Region”. 5: a meeting of two air masses with major differences in temperature and moisture.

Complete a write up about the elements in Ammonia and explain how the elements bounded to create the new substance.
Answer:
Explanation:
Ammonia consist of nitrogen and hydrogen.
Chemical equation:
N₂ + H₂ → NH₃
Balance chemical equation:
N₂ + 3H₂ → 2NH₃
We can see that nitrogen and hydrogen react with each other and from ammonia.
Nitrogen is present in group 5A. The atomic number of nitrogen is 7. Its atomic mass is 14 amu. It has 5 valence electron.
Electronic configuration:
N₇ = 1s² 2s² 2p³
we can see there are five electron in outer most shell. Thus, nitrogen needs three more electrons to complete the octet. When it combine with other atoms it gain three electron from them
While hydrogen is present in group 1A. It has one valence electron. In ammonia (NH₃) when nitrogen react with hydrogen it gain three electrons thus three atoms of hydrogen combine with one atom of ammonia because one hydrogen atom can share only one electron. Covalent bond is formed between nitrogen and hydrogen and new substance formed is called ammonia.

please help timed !! due rn !! What happens to particle motion as two substances come to thermal equilibrium?
Answer:
When two substances that are of different temperatures are brought together and there is heat transfer such that the substances come to thermal equilibrium, the effect on the particle motion are as follows
1) The particle motion of the hotter body reduces, because its temperature reduces
2) The particle motion of the colder body increases, because its temperature increases
3) For gases, the volume and or pressure reduces for the hotter body, and if the temperature of the gas falls below the boiling point temperature, the gas will change into liquid
For the colder gas, only the volume and or pressure increases and the temperature rises
4) For liquids, if the temperature of the hotter liquid falls below the melting point, the hotter liquid will become a frozen solid
For the the colder liquid, if the temperature is raised above the boiling point, the liquid changes into gas and the temperature does not rise above the boiling point temperature, until all the cold liquid has evaporated
5) For solids, the vibration of the particles of the hotter substance reduces and the solid becomes more brittle
For the colder body, the rise in temperature causes an increase in vibration of the particles, and if the temperature rises above the melting point, the colder solid will begin to melt

What is true about warm, saturated air?
It contains less water vapor than cold air.
It contains the same amount of water vapor as cold air.
It does not contain any water vapor.
It contains more water vapor than cold air.
Answer:
It contains more water vapor than cold air
According to the process of conduction which take place from hot to cold end warm saturated air has more water vapor than cold air.
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
As per the concept of conduction, warm hair has more water vapor than cold air, thus the correct option is that warm, saturated air has more water vapor than cold air.
