Less resistance/friction on concrete.
Less resistance/friction on concrete.
Concrete because the sand would burn it.
Automobiles have made it easier and faster to travel, in terms of transportation.
Less resistance on a smooth concrete road.
It's helps us by making travel easier and faster.
Pros : travel easy, got to places faster Cons : air pollution, gas prices
The speed of sound depends only on the temperature of the gas for an ideal gas. This implies that the ambient pressure on top of a mountain doesn't affect the propagation of sound in air. So the speed of sound should be larger in hot desert air compared to cold air on a mountain top.
The bumpier the road, the more resistance the car has to move forward.
Sound would travel faster through one brick than the same amount of concrete based on molecular structure but if a wall were built with brick, mortar would be required, this mortar would slow the sound vibrations and scatter them, while the same size wall made of concrete is solid and would then conduct sound faster than the brick wall.
The automobile epitomize the new values of mass consumption and the changing patterns of leisure in America. It allowed people to travel further distances at faster rates.
Freedom to travel.
