Which conclusion can BEST be supported by the illustrations?
lol i’m in your physical science class what was the answer
Without seeing the specific waveforms for Wave A and Wave B, we cannot draw a conclusive comparison. However, comparing waveforms can give insights into aspects such as frequency, wavelength, amplitude, and phase difference.
Without the actual illustrations of waveforms for Wave A and Wave B, it's not possible to draw a reliable conclusion about these waves. However, generally, by comparing waveforms, we can discern their frequency, wavelength, amplitude, and phase difference. For example, if Wave A has more complete cycles passing a certain point in a given time than Wave B, we can conclude that Wave A has a higher frequency. If wave A has a higher peak than Wave B, we can say that Wave A has a greater amplitude. These are examples of the types of conclusions one could potentially draw from waveforms, but without the specific waveforms for Wave A and Wave B, any conclusion here would be purely hypothetical.

The work performed on the spring is
W = 1/2 k x²
so that
4 J = 1/2 k (0.11 m)² ⇒ k ≈ 660 N/m
Then by Hooke's law, the force required to hold the spring in this position is
F = k x = (660 N/m) (0.11 m) ≈ 73 N
