how are magnetic field lines helpful when studying magnets?

Answers

Answer:

If the magnetic field lines are closer to each other, the magnetic field strength is generally stronger. For example, in a bar magnet, the magnetic field lines are always densest when they are close to either pole. This signifies that the magnetic field gets stronger as we get closer to its source.

Explanation:

Explanation:

Earth's magnetic field is thought to play an important role in making the planet habitable. Not only does a magnetic field set the direction of our compass needles, it also acts as a shield of sorts, deflecting away solar wind that might otherwise eat away at the atmosphere.

What do you do if a dog is chasing you?

Answers

Answer:

run.

Explanation:

Answer:

The first thing to do if a dog charges you is to remain calm.

If the dog is trying to bite you, try and block the attack with something you have on you.

If the dog is large enough to push you over, tuck yourself up into a ball and clasp your hands around the back of your head

If the dog bites and holds, je.rking away can damage you more than if you stay in position. Remember to stay calm.

If you have the chance to run, try to get somewhere out of reach of the dog.

If you are near playground equipment, climp out of reach of the dog.

What do you have to do to become faster at running?

Answers

Answer: Get stronger. Strength is critical to running fast because the more force you can exert against the ground the faster you can run.

Apply your new strength. Being strong is important for sprinting, but the ability to apply it is even more important. Sprinters move in a horizontal direction.

Take longer steps more quickly. Today, the concept of exerting more force against the ground is very popular for improving speed. ...

My actual question: How does the universe work and what is beyond it. It doesn't have to be correct, it just needs to be a theory (at least)

Answers

The universe is everything, so it isn't expanding into anything. It's just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there's no center they're expanding from and no outer edge to expand into anything else.

There is nothing beyond it because it’s just universe and it goes forever

I do not know the exact question. But I can explain what weathering and erosion is to possibly help you.
Weathering- The process of wearing or being worn by long exposure to the atmosphere. (Usually rain and wind).
Erosion-The process of eroding or being eroded by wind, water, or other natural agents. (Such as acid rain over time slowly cutting into a rock and breaking it down into minerals).

Plants take in carbon dioxide (CO2) and release oxygen (O2) during day time when they undergo the process of photosynthesis and they take in O2 and release CO2 during night as a result of respiration.There are 3 photosynthesis pathways adapted by plants for carbon fixation namely C3 pathway (Calvin cycle), C4 pathway and CAM pathway (Crassulacean Acid Metabolism). C3 and C4 are common among land plants and among these two, C3 is the most common.CAM pathway can be seen in desert plants and epiphytes (i.e. plants that live on other plants). Unlike C3 and C4 plants, these plants keep their stomata closed during day and open it during night for fix CO2 in the form of malate and releases O2. They do it so, to prevent loss of water due to sunlight. During the day, they breakdown the malate and use the released CO2 through Kalvin cycle to produce sugars, similar to C3 plants. So, CAM plants releases oxygen during night.Peepal tree is a hemi-epiphyte in its native habitat i.e. the seeds germinate and grow as an epiphyte on other trees and then when the host-tree dies, they establish themselves in the soil. When they live as an epiphyte, they use CAM pathway to produce carbohydrates and when they live on soil, they switch to C3 type photosynthesis. So, a Peepal tree can also release oxygen during the night depending on whether it is an epiphyte or not.Other plants that give out oxygen at night are Areca Palm, Neem tree, Snake plant, Aloe Vera, Gerbera and Tulsi.
