Can a 9 year old take 50 degrees and 80 degrees to class without it?

You don't need to bring it, it's best to bring it to watch computers and TV. Take care to protect your eyes, preferably not deepening it any further.

9 years old with 50 degrees and 80 degrees to class, you don't need to bring it after class. Ordinary. You don't need to wear glasses to see people. Of course, you have to bring it with you to class. However, children should pay special attention to it, and don't become more myopic at that time.

Don't wear it, now it's pseudomyopia, and when looking at things, you can correct your child's vision by standardizing your sitting posture, paying attention not to overuse your eyes, or doing eye exercises.

If it is myopia, there is no need to have a low degree after all, just pseudomyopia, if it is astigmatism, you must take it, otherwise, the degree will grow rapidly.

Sleep on one side at 50° and 80° again. You can leave it without wearing it after class.

Yes, there are more than 200 on both sides of the third year of junior high school in my family, and I picked it up after school.

I think I often bring it, if you don't bring it, your eyesight will deteriorate faster! If you don't take good care of yourself from 9 years old to adulthood, it will definitely be 400+ in your 20s, but the current technology can do laser surgery. Normal. After doing the eyesight, the table is blown off.

Of course, you can, but take care of your eyes.

Wearing it often to look at the near place is easy to aggravate myopia, and it does not affect life, and you can not wear it without wearing it, with the advice of people who have come over for thirteen years.

It should be worn to prevent myopia from deepening.

When wearing glasses, the doctor will explain what to bring, how long to bring, and listen to the doctor.

e means east longitude, i.e., east longitude; n stands for North Latitude. Therefore, the meaning of the title is: 30 degrees to 80 degrees east longitude, 50 degrees to 100 degrees north latitude.

It's the same with mine, he went up when he was closed, I just couldn't find this reason, did you find it.

Is yours an industrial oven? You can call ** to ask the manufacturer,

Ask the manufacturer if the oven is broken.

The volume of 0 4 degrees Celsius decreases with the increase of temperature, and the volume above 4 degrees Celsius increases with the increase of temperature. 0 5 liters does not indicate that it is in that case, so it is not possible to calculate the specific volume.

It must have changed a lot, and I don't know how much it has changed, is this a question?

Some are tall.

You see if the fan is working properly on the CPU.

Apply the silicone grease of the CPU again, and replace the CPU fan with a better one.

tan(15)=tan()45-30) is using the tangent formula for the difference between the two angles.

tan (20) did not learn.

You! I have to say that you are really awesome.

5000+ with NF520 is no problem.

But you actually have a 9800gt !!You're so awesome, idol brother!

Generally, NF520 is equipped with a maximum of 9600GSO, and you are still on 98GT...

Obviously, the motherboard can't withstand it. This is not something that can be solved by adding a fan.!

Generally speaking, a 7750 CPU plus a 720 or 770 motherboard and a 9800GT are pretty much the same.

Your temperature is obviously too high, completely abnormal.

Generally speaking, the GPU temperature of the graphics card is the highest, followed by the CPU, and then the motherboard, and now you either go for a better motherboard, or change to a lower graphics card.

If you continue to use this combination, it is very responsible to say that there will be a problem!

This temperature is relatively abnormal, and the most direct way is to add a cooling fan.

Now this climate is normal, but the motherboard temperature is too high.

Add a fan to the back of the case, 8 inches or 9 inches, and see the screw hole distance set at 20-30 yuan.

Generally speaking, it depends on the model, I don't know what model of CPU you have, the average theoretical CPU temperature is 40-80

But if you are above 70, you should pay attention.

Your CPU fan is either not powerful enough or it's time for a better one.

1. The energy used is equal. The above few have said, I won't talk nonsense;

2. The time taken is different. If the temperature of the heat source is constant, then the temperature difference between them is different for the first and second time, and the temperature difference is related to the speed of heat transfer. So different.

Use the same energy if the mass is the same twice.

Because q sucks cmt0, t0=t0

c water m water 1t0 = c water m water 2t0

So if m1=m2

Q suck 1 = q suck 2

Absorb the same amount of heat, and of course for the same amount of time.

Come on!! The specific heat of matter is the same as density, it is a property of matter, it does not change with the change of external conditions.
