My sister's winter holiday, there is such a question
"" Cao Chong said that the way is very clever, can you think of other ways? Do you know? "
I am not understood, why do teachers love this?
Anyway, I won't, my university, I can't even get up.
Ask everyone's good way ...
The following is a collection of answers:
You can find a swimming pool, high water high, the original water level, kick the elephant into the pool, recall the water level. The volume can be calculated. Let me find that the density is estimated, and the weight can be obtained.
Place an elephant on an empty partition wall, then place an electron with a low enough place, then use the spring to measure the absolute value of the electron, and then calculate the quality of the elephant according to the gravitational law, should it be quite accurate method what
Pull open the refrigerator door to close the refrigerator door in the elephant sessile and then referred to as the weight of the refrigerator minus the original weight of the refrigerator (the self-weight of the refrigerator can consult the manufacturer)
Tell it to put an elephant, say that
Throw the elephant from the high floor, measure the time of its landing. With Newton's second movement, it is easy to have the quality M. (very obviously this brother is the physics of Yau Shi ") ...)
The topic requires the advanced method of Cao Chong, you have not highlighted the word "advanced". My way is to send an elephant to a small asteroid with an ordinary call to calculate the magnariatte stars with the silver river massage, and then calculate the elephant weight in general relative.
Digging a big pit, rushing in the elephant, then filling the land, how many earth flips is multiplied by elephant's density.
Let the elephant collide with an instrument at a certain speed, measure its impulse, divide the speed is quality.
Use a penalty, hit her saying!
Slightly improvement, don't have a stone, have to move it, let a few people jumped to the boat, let them report their own weight. (Well, I said that a friend of this year is such a elephant, and the result is almost killed.)
Sliced a small piece of meat to make a density to put an elephant into the bathtub, the weight of the water is that the volume is the weight of the royal crown.
Cook the elephant, see how many people can enjoy, the calculation method is: 5 two × male number 2 two × girl number = elephant body weight. (The elephant is not all meat, and there is a hawk Ivory, like bone, like hair to go to the density of meat)
Redefine the quality unit, which is set to one ton with a elephant, so all elephants quality is a ton.
Mr. Galileo is alive.
Thinking for a long time, I feel that the leverage principle is relatively appropriate. Well, everyone knows, I use a rod scale.
Cut the block, one pound!
After inflating with a hydrogen balloon, let the elephant suspended, and then slowly calculate it.
Cut the elephant to the scale (that is, the police check the car overloaded), can you directly get your weight? Xiao Cao did not have such advanced Dongdong, so I had a stupid method with "clever" :)
Come to a mother, tempting it
Looking for a ice sheet to see how much force pulls, calculate the friction coefficient, and then catch up with an elephant and use a force to calculate the quality.
With elephant to ski
Unlimited differentials in elephants, can be guided
How much is UPS or FEDEX?
Let the elephant go to Pielove friends, generally should talk to high weight ...
I don't know if I have made bacon, I still have multiple.
In the Journey to the West, I will find a magic to collect the elephant, and then call the weight change before and after. Yes, talk about this, I think it
Which fairy is the gourd? I don't know how he greeted people on the road. . .
Find a rushing N ton bridge to catch N only elephant to bridge the collapse elephant weight = N / N-1, the larger the bridge weight, the larger the value, the value is quantified
Call or send an email Ask Cao Chong, or simply google
Serious, serious, we are called here! !
Speaking of a relatively regular, find a truck, take an elephant, driving a distance, see how much oil (quality and oil model should be, no one). how is it?
Tie thin wire on Cao Chong's boat, will get up, measure the change of the electric resistance of the electric wire, calculate the length of the length according to the resistance and length, the cross-sectional area, then do finite element analysis, calculate the weight, then conversion Quality
From elephant birth, daily recording elephant absorption and excretion, plus skin exudation, breathing with breathing, so that the precise quality of elephants can be obtained. It is estimated that it is an animal physiologist.
You find a seesaw, put the elephant in a paragraph and jump from one hundred layers upstairs, watching elephants can play more high and then
Double assembly, look at it
Oh, put the elephant with oil into a slag. Collect emissions CO2 and H2O, with oil volume and O2.
Slag - oil volume -O2 weight H2O mass CO2 mass = elephant weight
The deception is too thin, he only has 1 gram, he is not able to do it.
Just say: "Very full, weight is **** kg"
Stocked with the recorder, then find someone to make recording, you can conclude.
Penalty, hit her saying - the world's first
