MTL - I Have a Store In the World of American Comics-v2 Chapter 19 correct formula

But it doesn't mean that 0.001ав+1I is equal to 1L? This formula will hold.

And the correct formula should be:

△=(x)ав⊕(c)I.

t△?? =(d)?

(x), (c) (d) are unknowns

⊕ is to stir, to mix.

t is time, which is known to be 168 seconds.

?? stands for unknown.

And the process of this formula is tortuous and long. Zhou Wenwen believes that his third grade level will definitely not be able to supplement this formula. When he sees Iron Man, he can talk to him.

But as the saying goes, practice brings true knowledge, Zhou Wenwen can try 1L unit? Ash energy, how powerful is it.

Thinking of this, Zhou Wenwen's interest suddenly increased. He pressed the button of the armor on his left hand to take over the αβ electron absorption cycle conversion and emission? Ash energy 0.1 system, called up 3 degrees of αβ energy and 10A current, and quickly introduced it into the acceleration tube, circulating flow .

The time setting is to fire after the time reaches 1 second.

So after more than 2 minutes, that is, 168 seconds and 1 second later, a white energy beam shot out from the mouth of the electronic cycle device and hit the tail of the pickup truck 5 (5.1) meters away from Zhou Wenwen within 3 (3.02 seconds). armor sheet.

The tail armor of the pickup immediately left the tail of the pickup, and flew more than 50 meters within 6 (6.72) seconds before landing. According to the surveying and mapping of hunters, it was 57.21 meters.

After getting the value, Zhou Wenwen began to calculate, first according to the formula t△?? =(d)? This first value formula will yield:

1×(3ав+10A)?? =(d)? This second value formula, in view of "0.001 degree ав+1A is equal to 1L?", import the second value formula and solve it to get:

1×3+1×10?? +2.997ав=30L?∝2.997ав.

∝ stands for surplus, parcel.

It is known that Q=I2Rt, and the unit of Q is J, that is, Joule, which is the unit of energy and work. 1 Joule of energy is equal to the work done by the action point of 1 Newton moving a distance of 1 meter in the direction of the force.

Then substituting 30L?∝2.997ав into the formula of I2R, the third value formula of Q=30L?∝2.997ав×t will be obtained.

In view of the fact that the tail armor of the pickup truck flew out 57.21 meters, import the third value formula and solve it to get:

57.21(J)Q=30(L)∝2.997(degree) ав×t is the fourth value formula.

It is also known that the time for the pickup truck tail armor to fly out is 6.72, and the fourth value formula is imported to solve it and we can get:

57.21(J)=30(L)∝2.997(degree) ав×6.72(s)

Simplify to get:

8.51339286(J)=4.46428571(L)∝0.445982143(degree) ав×1(s) This fifth value formula.

So what is the use of this 5th value formula? Is it correct?

Zhou Wenwen didn't know the answer, but he knew that the fifth value formula could be used as a comparison.

Zhou Wenwen took a deep breath, and pressed the button on the left arm armor again to take over the αβ electron absorption cycle conversion and emission? Ash energy 0.1 system, call out 15 degrees of αβ energy and 18A current, and introduce it into the acceleration tube to circulate.

If the time is still set, it will be launched after the time reaches 1 second.

In this way, after 168 seconds and 1 second, a not thick white energy beam shot out from the nozzle of the electronic cycle device with a bang, and hit the front of the pickup straight, and then an unexpected thing happened. .

The front of the pickup did not fly out like the rear armor of the pickup, but melted a small hole and exploded immediately. Obviously, the energy beam penetrated the oil pipe of the front of the pickup, and the high temperature ignited the gasoline. produce an explosion.

So how to calculate this second example?

Zhou Wenwen was lost in thought.

Zhou Wenwen knows that under normal atmospheric pressure, the spontaneous ignition point of gasoline is 427°C.

However, gasoline volatilizes quickly, and gasoline vapor is easily ignited when mixed with air, which will also cause the flash point of gasoline to be lower than about 28°. Generally, the lower the flash point, the higher the auto-ignition point.

The flash point is the temperature at which the oil can flash when it is heated to a certain temperature when it encounters an open flame, and the auto-ignition point is the temperature at which the oil comes into contact with enough air (oxygen) to burn when it reaches a certain temperature.

To be on the safe side, Zhou Wenwen preliminarily estimated that after the energy beam penetrated the oil pipe, when the gasoline and the air were fused, the energy beam with a surface temperature of 20 degrees extinguished the gasoline and eventually exploded.

Apart from gasoline, the key now is the energy beam with a surface temperature of 20 degrees.

And this involves the specific heat capacity.

Specific heat capacity, English abbreviation SHC, English full name SpecificHeatCapacity, symbol c.

SHC, referred to as specific heat, also known as specific heat capacity, is a physical quantity commonly used in thermodynamics, used to express the ability of a substance to absorb or dissipate heat. The larger the specific heat capacity, the stronger the material's ability to absorb or dissipate heat.

That is, the amount of heat absorbed (or released) per unit mass of a substance to raise (or lower) unit temperature.

The unit in the International System of Units is joules per kilogram Kelvin [J/(kg·K)] or joules per kilogram per degree Celsius [J/(kg·℃)], where J refers to joules and K refers to the thermodynamic temperature scale, that is, the order The energy required to raise (or drop) the temperature of 1 kilogram of matter by 1 Kelvin.

And according to this theorem, the most basic formula can be derived as follows:

c=Q/m (ΔT)

Q is the amount of heat absorbed (or released), m is the mass of the object, and ΔT is the change in temperature after the heat is absorbed (or released).

(In the textbooks for junior high school, ΔT is written as Δt. In fact, this is not standardized. In our daily life, ℃ is often used as the unit of temperature, and K is rarely used, and ΔT=Δt. Therefore, Δt is used in middle school, but international or higher The scientific field still uses ΔT).

It is known that the temperature is 20 degrees, the specific heat capacity of pickup gasoline is about 0.8 to 1.8, the minimum value of pickup gasoline oil pipe is 1 liter, and the maximum is 6 liters. Four formulas can be obtained by importing the formula:

0.8=20/1 (ΔT)

0.8=20/6 (ΔT)

1.6=20/1 (ΔT)

1.6=20/6 (ΔT)

ΔT variant solution ~www.novelbuddy.com~ It can be seen that after the energy beam hits any object, it can generate at least 2 degrees in 1 to 3 seconds, and the maximum temperature can be 25 degrees.

And t△?? =(d)? The ? in this first value formula? , there is also a corresponding description, that is, the temperature rises, that is,

△=(15)ав⊕(18)I.

3△?? (warming) = (d)?.

But Zhou Wenwen was not satisfied with this, so he decided to try again.

He pressed the button of the left arm armor again, and took over the αβ electron absorption cycle conversion and emission? Ash energy 0.1 system, and this time he called up the remaining 92 degree αβ energy and 73A current, and introduced it into the acceleration tube, circulating flow .

The time is still set to launch after 1 second, and the target this time is a piece of iron with an area of ​​1 square meter and a weight of about 15 kilograms.

So after more than 2 minutes, that is, 168 seconds and 1 second later, another white energy beam shot out from the nozzle of the electronic cycle circulation device, and hit the 30 (29.1) meters away from Zhou Wenwen within 6 (6.12 seconds). Iron sheets.

The iron piece seemed to be thrown out with great force, leaping more than 200 meters in one fell swoop, and went deep into the ground. The whole process took less than 3 seconds, and the hunter's survey showed that the iron piece flew 275.124 meters, and the flight time was 2.712 seconds.

After getting the value, Zhou Wenwen started the calculation again, first according to the formula t△?? (heating) = (d)? This first value formula will yield:

Chapter 020 Announcement of the seventh value multinomial formula, is there an eighth value?
