Calculating power by speed

1. computing power is trained. When we were in primary school, we didn't have a calculator. The topics were all written and oral arithmetic. In junior high school, when I had a calculator, I always used it. After a period of time, I found that my computing ability had declined. I put it aside
no matter how large the number is or how complex the operation is, you should insist on doing it yourself; I also like mental arithmetic. I don't need a pen to do it. For example, 18 * 37 can be 20 * 37 or 18 * 40

2. In fact, any problem can be overcome.
I think you can find some problems.
it must be problems with complex process and complicated calculation (such as the last step of Mathematics)
it is best to provide reference answers, Then you work on the draft paper step by step
until you match the standard answer
make a plan for yourself
for example, do a question one night
secondly, I think you should be calm when doing the question
sometimes say to yourself
write down step by step
don't worry
try to write clearly on the draft paper
finally
you can also do it Think about the mistakes you made in the past.
to sum up,
at least pay attention to this in the future.
finally, I wish you success in the college entrance examination.
after all, I don't think you should be too nervous about the college entrance examination.
as long as you do it step by step,
no matter how simple or difficult the test paper is,
you should have a good attitude.
you will definitely have a good score uck

3. Gravitation is about equal to gravity, so GMM / R ^ 2 = mg, so
G = GM / R ^ 2
G = GM / R ^ 2
4. This is a problem of impulse. Let the momentum before and after a person touches an object change to M & # 8710; 5. In the process of collision, when the force of the object on the human is n and the collision time is t, there is M & # 8710; V=(N-Mg)t!
this n is equal to the human pressure on the object in the collision process. Because t is very small, this n is generally very large, far greater than gravity. The problem can be simplified as:
M & # 8710; V / T = n, this # 8710; V / T is the average acceleration of people in the collision process
I don't know if I'm wrong!

5. You mean to use the Internet to integrate the computing power of mobile phones, right? At present, this technology is called distributed computing. Astronomy and extragalactic civilization use this method. There is no software on the mobile phone to achieve this goal, it is possible in theory!
6. Focus on the calculation, develop your own calculation tips, limit the time to calculate the accuracy of the exercise, and do not use a calculator
7. G is the sign of the acceleration of gravity, which is specified
8. 1. Through the effect of gravity acceleration: the time and displacement are measured by free fall test, and the swing length and period are measured by single penlum test
2, through the direct expression of gravity acceleration: measuring gravity and mass;
2, through the direct expression of gravity acceleration: measuring gravity and mass;
9. =(1 / 2) * 9.8 * T ^ 2, where t is replaced by the cell reference or the name of the representative area
10. It is suggested to have a look at the relevant professional websites or find relevant professional books. It's hard to say here
