The speed of sound in the atmosphere is a constant that depends on the altitude, but an aircraft can move through the air at any desired speed. The ratio of the aircraft's speed to the speed of sound affects the forces on the aircraft. Aeronautical engineers call the ratio of the aircraft's speed to the speed of sound the Mach number, M It can also calculate the frequency if the wavelength and the medium are known or the speed of sound if its frequency and wavelength are known.

Definition: The unit kilometers per hour (symbol: km/h) is a unit of speed expressing the number of kilometers traveled in one hour. History/origin: The unit of kilometers per hour is based on the meter, which was formally defined in 1799. According to the Oxford English Dictionary, the term kilometer first came into use in 1810. It was not until later in the mid-late 19 th. In the air, the answer is no and yes. A modern aircraft such as the Airbus A380 flies at a cruising speed of about 900 km/h. Its actual speed over the ground can vary quite a lot depending on.

Note that the speed of sound varies according to the medium it travels through, but since things traveling on Earth are surrounded by air at all times, we will consider the speed of sound in air, which happens to be 767 mph (or 1234 km/h) The US military aims to fly a hypersonic plane at 20 times the speed of sound by 2016. The X-plane will travel at Mach 20 (roughly 20,900 km/h), which means it could fly to any place on earth in. In principle, he has a constant speed of 50 km/h, but he can drive at a lowers peed and accelerate earlier, provided that the speed on the line A-A is exactly 50 km/h. When the front of the vehicle passes the line A-A, the throttle control shall be shifted to the maximum throttle position as rapidly as possible and kept in this position until the rear of the vehicle passes the B-B As luck would have it, your weapon fires at the exact same speed that you are traveling. So, you are flying along at 300 km/h and you are about to shoot a bullet/cannon/whatever in the opposite.

Mach is the ratio of an object's speed to the speed of sound. For example, something traveling at Mach 5 is traveling at 5 times the speed of sound. The speed of sound varies depending on many factors. In dry air, at 0 degrees Celsius, the speed of sound is about 331.3 meters per second The speed of sound through warm air at sea level has been measured at 346 meters per second or 0.346 km per second. That is the same as a car traveling about 780 miles per hour! Even most jet airplanes do not travel that fast. When a plane does go faster than speed of sound, it is said to break the sound barrier and a soni The speed of sound IS 343 m/s; if, you are at sea level ( 1 atmosphere pressure) and the temperature is 20 C ( or 68 F) and the air is dry. However if; the temperature is 27C (or 80F )' then the speed of sound is 347.5 m/s In km/h, this is: 330 ÷ 1000 = 0.33 km/s. 0.33 × 3,600 = 1,188 km/h. Making calculations Different calculations can often be needed to work out rates such as speed, and sometimes units may need.

In 1906 Dorothy Levitt broke the women's world speed record for the flying kilometer, recording a speed of 91 mph (146.25 km/h) and receiving the sobriquet the Fastest Girl on Earth.

14 A car travels 100 km. The journey takes two hours. The highest speed of the car is 80 km / h, and the lowest speed is 40 km / h. What is the average speed for the journey? A 40 km / h B 50 km / h C 60 km / h D 120 km / h 13 What does the area under a speed-time graph represent? A acceleration B average speed C deceleratio Speed and accident risk. A higher speed increases the likelihood of an accident. Very strong relationships have been established between speed and accident risk: The general relationship holds for all speeds and all roads, but the rate of increase in accident risk varies with initial speed level and road type During the X-15 program, 13 of the flights (by eight pilots) met the USAF spaceflight criteria by exceeding the altitude of 50 miles (80.47 km. 264,000ft.), thus qualifying the pilots for astronaut status; some pilots also qualified for NASA astronaut wings. Its fastest speed recorded is 4,519 mph (7,273 km/h) while manned by pilot Pete Knight Please enter distance or time, the other value will be calculated. One year is counted as 31557600 seconds (365 1/4 days). Examples: the average distance of the moon from earth is 384400 kilometers The speed of light is faster than the speed of sound. In addition, lightning creates thunder, therefore it happens first, therefore must be faster. See the related link for more information
