<h3>Answer</h3>
option C)
The wavelength has a length between 7.0 cm and 8.0 cm and the amplitude lies between 1.0 cm and 2.0 cm.
<h3>Explanation</h3><h2>1)</h2>
The amplitude of a wave is the height of a wave as measured from the highest point on the wave, peak, to the rest point or from the lowest point on the wave, trough, to the rest point.
By looking at the image
rest point is at 5cm and crest is at 3.3 cm (y-axis)
so amplitude = 5 - 3.3
= 1.7 cm (approximately)
<h2>2)</h2>
Wavelength refers to the length of a wave from one peak to the next.
one crest is at 2cm and the other crest is at 10cm (x-axis)
so wavelength = 10 - 2
= 8 cm (approximately)

Amy because she is lighter, so the more force will be put on her
Answer:
air pressure increases and temperature decreases

Hope this helps
There are many factors which contributes as to how a machine will be processing the input energy and convert it to output energy. Even with identical mechanism, these factors will have major effect on the output. Some factors are deflection, friction and wear. Some system maybe exposed to poor lubrication than the other which'll produce more friction and wear thus lower mechanical advantage.
Answer:
2.75 m/s^2
Explanation:
The airplane's acceleration on the runway was 2.75 m/s^2
We can find the acceleration by using the equation: a = (v-u)/t
where a is acceleration, v is final velocity, u is initial velocity, and t is time.
In this case, v is 71 m/s, u is 0 m/s, and t is 26.1 s Therefore: a = (71-0)/26.1
a = 2.75 m/s^2
