Answer:
A=0.199
Explanation:
We are given that
Mass of spring=m=450 g=
Where 1 kg=1000 g
Frequency of oscillation=
Total energy of the oscillation=0.51 J
We have to find the amplitude of oscillations.
Energy of oscillator=
Where =Angular frequency
A=Amplitude
Using the formula
Hence, the amplitude of oscillation=A=0.199
What? What is being asked?
Answer:
gravitational potential energy at point A.
Based on the 95% confidence interval, the conclusion would be that the whale-watching company has a 95% chance of seeing between -.507 and 1.307 whales on any given day.
<h3>Why can this conclusion be drawn?</h3>
The test was to find out how many whales could be seen on a given day and this was tested at a 95% significance level.
The 95% confidence interval was shown to be (-0.507, 1.307). This means that there is a 95% chance that between -0.507 and 1.307 whales will be seen on a given day.
