Answer:
Mechanical waves are defined by which of the following?
C. All of the above
Since, mechanical waves are created when an energy source vibrates, and they carry energy from one place to another through a medium, this is the right option.
Mechanical waves need an energy source to produce them?
True because a mechanical wave needs an initial energy input.
A wave has a wavelength of 100 mm and a frequency of 6 Hz. What is its speed?
600 mm/s
Wave speed = wavelength X frequency
Wave speed = 100 X 6
Wave speed = 600 mm/s
Amplitude of a wave is?
B. How high the wave is from resting point
By definition of amplitude.

Answer:
When you are running the most important force that you should understand is friction. Friction is a force that opposes movement between two objects, but for runners friction makes you faster. Friction gives you a better and more efficient way to use your energy into speed.
