If everyone sat on the ground in the ocean, to what extent will the water rise? – Zakif and Victor
Virtual questions, such as what can happen if everyone goes on the face of the earth to swim simultaneously, fun to think. And the use of mathematics, you can approach a real answer. Let’s start looking at a smaller version of the same question.
The mathematics bathtub
If you fill the bathtub all the way to the top and jump, then you know that you are in cleaning. The water flows because your body pushes it away – a thing called displacement. Since the pelvis contains a bottom and solid sides, the only trend in which water can go up and out.
The amount of space called an object – in this case, is called the folder. The size of the water that overflows the pelvis is equal to the size of your body.
Now think about the situation in which the bathtub is only full. During jumping, your body size still pays water up. You can calculate the amount of water level in the sink with a few simple mathematics equations.
Suppose the bathtub is a rectangular box. You can know how high the water level is when you sit in the sink by looking at the amount of size you add to the sink and what is the size of the size you publish in this size. The amount that rises the water level is equal to the added size divided into the area.
For a 5 -foot shower basin and two feet width, the area is 10 square feet.
Now, let’s get to know your voice level. To facilitate mathematics, we assume that, like a bathtub, is also a rectangular box. Let’s say that you are about 4 feet and two feet (from left to right) and one foot depth (from front to back). Your body size will be 4 feet x 2 feet x 1 feet, or 8 cubic feet.
When you sit, you add approximately half of your body to the sink. This means that the high level of water is equal to the size of the half of your body, divided by the pelvis. Using the above estimated estimates, this leads to a rise in the water level of 4 cubic feet divided into 10 square feet, which is equal to about 5 inches. You will definitely notice that!
Scaling
You can think of oceans as a giant bathtub. More than 70 % of the Earth’s surface is the ocean, which gives this bathtub An area of about 140 million square miles. To find out the amount of water, we need to know the size of the people who sit in it and divide it on this ocean area.
Currently, almost there 8 billion people on Earth. Humans come in all sizes, from young children to adult adults. Suppose the average size is 5 feet – slightly larger than a child – with an average size of 10 cubic feet. Half of the body of each person will be immersed only when sitting, so only 5 cubic feet add to the water level. With a total of 8 billion people, you can calculate 5 x 8 billion, which gives 40 billion cubic feet to be added to the oceans.
But remember that this folder will spread over a wide area of oceans. Using the same mathematics in the bathtub as before, we divide 40 billion cubic feet of size on an area of 140 million square miles from the ocean.
Answer? The overall rise in the sea level will be about 0.00012 inches, or less than 1/1000 of the inch. If everyone is completely immersed in themselves, this would double the answer to 0.00024 inches, which is still only about Human hair show.
It turns out that the oceans are enormous – and human beings are just a decrease in the bucket.
Hello, curious children! Do you have a question you want an expert? I ask a very person to send your question to Uciouskidsus@theconversion.com. Please tell us your name, age, and city in which you live.
Since curiosity does not have the maximum age – adults, he told us what you also wonder. We will not be able to answer every question, but we will do our best.
