What is the relationship between the speed of sound and the temperature of medium?

The higher the temperature, the faster the speed of sound

The speed of sound is related to the temperature of the medium. What is the relationship between them?
Such as the title
I hope you can give the answer as soon as possible and accurately~

The higher the medium temperature is, the faster the sound transmission speed is

Temperature and sound speed
I know that the speed of sound is directly proportional to the temperature, but it is not that the higher the density of the medium is, the faster the speed is, the higher the temperature is, the smaller the density is, and the heat expands and the cold shrinks

No contradiction, hehe, is the medium single or diverse,
The speed of sound in the air is related to the temperature. The speed of sound in the air of 0 ℃ is about 332 M / s, while that in the dry air of 100 ℃ is 386 M / s
The higher the temperature, the faster the molecule oscillates

The speed of sound propagation in the air has a certain relationship with air temperature. The following table lists the speed of sound at different temperatures: air temperature (℃) 0 510 15 20 speed of sound (M / s) 331 334 337 340 343 (1) let the air temperature be x ℃, and use the algebraic expression containing x to express the speed of sound; (2) if the air temperature is 18 ℃, and someone hears the sound 5 seconds after seeing the fireworks, what is the distance between the person and the place where the fireworks are set off

(1) The speed of sound is: 0.6x + 331 (M / s); (2) when x = 18, 0.6x + 331 = 0.6 × 18 + 331 = 341.8341.8 × 5 = 1709 (m)

There is a pasture full of grass growing at a constant speed every day. This pasture can feed 17 cattle for 30 days and 19 cattle for 24 days. If the existing cattle are eating grass, after 6 days, 4 cattle die, and the rest cattle eat grass for 2 days, then there are cattle______ Head

The growth rate of grass: (17 × 30-19 × 24) / (30-24), = 54 △ 6, = 9; the number of original grass in pasture: 17 × 30-9 × 30, = 510-270, = 240; the original cattle: (240-6 × 4) / (6 + 2) + 4 + 9, = 216 △ 8 + 13, = 27 + 13, = 40 (

What is the formula of cattle eating grass
I really need it

Increment = (bull head × time - bull head × time) × time difference
Original quantity = (cow head - added quantity) × time
Bull head = original amount △ time + increase amount
Time = original quantity (bull head - increase quantity)
At the same time, it should be noted that the problem of cattle grazing is a special form of engineering problems. The key to keep the original grass quantity and grass growth rate constant is to determine two constant quantities
And the cattle grazing speed is set as "1"

The formula of grazing cattle

1) The growth rate of grass = (the number of cattle × the number of days eaten more - the number of cattle × the number of days eaten less) / (the number of days eaten more - the number of days eaten less);
2) The original grass amount = the number of cattle × the number of days to eat - the growth rate of grass × the number of days to eat`
3) the number of days that cattle eat grass = the original amount of grass (the number of cattle - the growth rate of grass);
4) The number of cattle = the original amount of grass △ the number of days to eat + the growth rate of grass

Who knows the formula of cattle eating grass?
A station starts to line up several minutes before the check-in. Assuming that the number of passengers is the same every minute, from the start of check-in to the disappearance of the queue waiting for check-in, it takes 30 minutes to open five check-in gates at the same time, and 20 minutes to open six check-in gates at the same time. If you want to make the team disappear in 10 minutes. How many check-in gates do you need to open at the same time?
Can I use the formula of cattle eating grass

Daily grass growth = (number of cattle * days of eating more - number of cattle * days of eating less) divided by the difference of days
The original amount of grass = the number of cattle * the number of days to eat - the daily growth of grass * the number of days to eat
*Refers to the multiplication sign
In time? Absolutely true

What does Newton's three laws say?
What are the three laws?

Newton's three laws Newton's three laws are important laws in mechanics, which are the basis of studying classical mechanics. 1. Newton's first law content: any object remains static or moving in a uniform straight line until it is forced to change this state by the force of other objects

Newton's three theorems

Newton's first law content: all objects in any case, when not affected by external forces, always keep static or uniform linear motion state. (also known as the law of inertia) explains: objects have the tendency to maintain static and uniform linear motion, so the motion state of the object is determined by its speed, no external force
