The answer is C radio waves are very high energy mechanical waves.
Speaking that the trash can absorb the momentum. It only should go 5
The number of repetitions per second is called the frequency and is the inverse of the period. The period, T, is normally measured in seconds, and the frequency, ν, in Hertz. When the oscillations<span> (or vibrations) affect the material around them a </span>wave <span>is formed which transports energy away.</span>
Answer:
0.48 N/cm
Explanation:
The original length is 10cm so with a force of 10cm, the extension will be 12.2-10=2.2 cm when force of 1N is exerted. Similarly, with a force of 3N, the extension is 16.4-10=6.4cm
The slope will be given by change in force/ change in extension and this is equivalent to the stiffness.
Change in force is 3-1=2 N
Change in exgension is 6.4-2.2=4.2 cm
The slope will be 2/4.2=0.4761904761904 N/cm
Rounded off, the slope is 0.48 N/cm and this is the stiffness of the spring.
