How to solve the serious morning sickness? Some people say, eat some acid.
Junior two students, some subjects are very serious, just recite the calculation formulas of buoyancy and force before solving problems!
Common physical formulas in senior two:
1, gravity: G=mg
2. Density: ρ=m/V
3. pressure: p=F/S
4. Liquid pressure: p=ρgh
5. Buoyancy:
(1), F float = F up-F down (differential pressure)
(2), f float = g-f (gravity)
(3), f float = G (float, pause)
(4) Archimedes principle: F float =G row = ρ liquid gV row.
6. Lever balance condition: F 1L 1 = F2L2.
7. ideal slope: f/g = h/l
8. Ideal pulley: F=G/n
9. Actual pulley: f = (g+g movement) /n (vertical direction)
10, work: W = FS = GH (lifting an object very high)
1 1, power: p = w/t = Fv.
12, working principle: w hand = W machine.
13, actual machinery: w total = w plus +w extra.
14, mechanical efficiency: η = w /W total.
15, pulley block efficiency:
(1), η = g/nf (vertical direction)
(2), η = g/(g+g motion) (excluding vertical friction)
(3), η = f/nf (horizontal direction)
My brother's middle school illness seems to be very serious ... alas, children nowadays are really worrying!
what can I say? He always says those inexplicable words, which shows that he has grown up and his feelings have begun to sprout! I'm interested in girls, maybe even * *!
This period, it is the most sensitive stage, he seems to understand feelings, but in fact he is extremely eager! There will also be sexual impulses! Occasionally * * * can also relieve inner restlessness, but if you indulge too much, it will do harm to your body and mind! He said: "The body is gradually rotting, and maybe this body won't last long." That's probably what he said! He couldn't help himself, but he was worried and scared, so he said so!
Tell him to his face! Or buy some books for adolescence, let him have a good look and help him get through this ignorant period safely!
My brother had a serious problem when he was in college. Is there any way to solve it? Universities can go to military service, exercise in the army for a few years and then come back to study, and there will be some benefits, such as the chance of failing the exam. I used to have a younger brother who was like this. He spent every day in the Internet cafe, and he failed to get his diploma. He went to the army in his junior year, and when I was in my third year of graduate school, he came back, and his mental state was much stronger than before. I think we can have a try. You can find out when to confess.
I checked it again. Every April, conscription begins immediately. You can Baidu about college students' conscription.
My brother is ill in the army. How to solve it? This should be analyzed according to the cause.
How to solve very serious insomnia? Ha ha. There's the easiest way.
Before going to bed every night:
1, put your thumb on your foot, from Taichong point to Pai, and pay attention to pressing your thumb deeply. It is normal to feel pain. Keep rubbing each foot for 3-5 minutes.
2. Then, lie flat on the bed and push your hands flat from your heart to your lower abdomen.
Continue to push 150, and you can add it later.
3. Immediately after the eyebrow, pinch a point called Sizhu point. Knead for 3 minutes.
According to the above practice to ensure that you get better insomnia, the human body has three major hazards-turbid gas, turbid water and turbid stool. Pushing your stomach every night will help you eliminate these three harmful things every day.
Arguing with my brother is very serious ~ ~ what to do! Is there any solution? It's okay. There is nothing wrong with my family. You are the elder brother, you should see who is wrong first. If you are wrong, you can take the initiative to think about whether your brother is worth it. If the younger brother is wrong, you should talk it over in other ways that he can accept, so that the contradiction can be solved.
The eye problem is very serious, how to solve it? My eyes are swollen in the morning. There are two situations, 1, poor sleep and poor rest. Pay attention to improving sleep quality in the future; When sleeping, your head is lower than your body. Pay attention to the pillow when sleeping, or raise the height of the pillow.
Eye edema is related to sleep, drinking water and sleeping posture. It is recommended not to drink too much water before going to bed.
Generally speaking, there are many reasons for eye edema, such as improper use of cosmetics, facial diseases, cardiac and renal insufficiency, angioneurotic edema and so on.
* * * can promote blood circulation around the eyes and effectively reduce swelling.
My brother was burned badly the day before yesterday. What should I do?
