The speed of the wave is 1500m/s
What is the speed of a wave?The speed of a wave is determined by its wavelength and frequency. It is measured in meter per seconds. It is calculated from the expression speed= frequency ×wavelenghth. For example, if a wave has a wavelength of 5m and a frequency of 500 Hz , it's velocity is 500×5 =2500m/s
Similarly, the wave in question is of wavelength 3m and frequency 450 Hz , therefore it's speed will be calculated as ;
speed = frequency × wavelength
speed = 450×3= 1500m/s.
therefore the speed of the wave is 1500m/s.

sketch a pavement serviceability curve, label the axes, and indicate initial and terminal serviceability
In the given figure we see the sketch of a pavement serviceability curve, label the axes, and indicate initial and terminal serviceability.
To fulfill the requirements of the Road Test, rather ordinary terms were given specific definitions as follows:
Present Serviceability: the ability of a specific section of pavement to serve highspeed, high-volume, mixed (truck and automobile) traffic in its existing condition. (Note that the definition applies to the existing condition that is, on the date of rating not to the assumed condition the next day or at any future or past date.)
This definition applies to the Road Test and can apply to any primary highway system, the system would easily be modified for use with city streets, farm roads, etc. Obviously, serviceability must be defined relative to the intended use of the road.

What is the only force acting on a freely falling object?
The gravitational force is the sole external force acting on an object falling through a vacuum.
What forces are at play when something is falling?A fall also involves the force of gravity pulling an object downward. The force of gravity is imbalanced at the beginning of the descent. The result is that the thing picks up speed or accelerates. It experiences aerodynamic drag or air resistance as it speeds.
What is a free fall's force?
As the only force acting on an object that is falling freely is the downward-acting force of gravity, the object feels weightlessness. The item accelerates at a rate equal to that of gravity. The object is subject to zero net force.
