Speed of sound The speed of sound is often expressed in meters per second but can also be converted to kilometers per hour. This speed of propagation of sound waves is very variable and depends mainly on the temperature as well as the density (density) of the medium (such as air, water...
Example: The speed of sound in air is 330 m/s. Example: The car is travelling at a speed of 60 Km/h. Speed Unit Conversion To convert speed from Kilometre per hour (Km/h) into metre per second (m/s), we multiply by . To convert m/s into Km/h, we multiply by . Reason: ...
5. Saying that a car is moving at 60 kmph due east implies that its velocity is 60 kmph due east, that is, it travels 60 km in the east direction in 1 hour. Negative and Positive Velocity To understand negative and positive velocity, consider the linear motion of a ball. As the ball...
The bike is fitted with all new 149.5cc, air-cooled, single cylinder engine that pumps out 12PS of power at 7,500rpm with a peak torque of 13Nm at 5,500rpm. 0 to 60kmph comes in mere 5.66s but the top speed of the bike is only 97kmph. The bike has good pickup from the beg...
High speed rail is marketed as a sustainable alternative to air traffic. According to the International Union of Railways, the high speed train “plays a key role in a stage of sustainable development and combating climate change”. As a regular long-distance train traveller in Europe, I ha...
How deep is the well assuming that air resistance is negligible and the time needed for sound to travel up the well is also negligible? 1/2 (9.8 m/s^2) x 3s^2 = 44.1m ***On a side note, why is there a 1/2 in front of gravity constant? 3. One car goes from 0 to 30 km...
