The ratio of chickens to ducks in Uncle Li's family is 5:3. If you raise 300 chickens, how many more chickens are there in Uncle Li's family than ducks? ```The more detailed the better, We need the formula! We need the integrity!

There are 300 chickens, because the ratio of chicken to duck is 5:3, so duck: Chicken = 5:3
So there are 500 ducks, 500-300 more than chicken = 200

When the taxiing speed of the plane reaches 85m / s, it leaves the ground and takes off. If the plane suddenly receives the command from the command tower to stop taking off when it reaches the take-off speed, the pilot immediately stops the plane, and the plane makes uniform deceleration linear motion, with the acceleration of 5m / S2 How long does it take for a plane to reach maximum speed from take-off? (2) How long does the plane take from take-off to stop?

10. The temperature of the track rises when the train is running on it The teacher said that this is the same as the friction between hands, overcoming the friction to do work I mainly want to understand why the temperature of the rail rises because of work Can it be understood as follows: When the train is running, it overcomes the friction to do work, and the internal energy increases and the temperature rises; Because the friction is mutual, the rail is also subject to friction. If the train is taken as a reference, the rail is moving and works against the friction Is that right?
