I am going to guess it shows that the balloon is going downwards because the speed of rise is in the negatives for the last 2.
Thank you for posting your question here at brainly. Below is Yoland's study:
<span>Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m.
</span>
I think the answer is "She can use constructive interference to generate a wave with an amplitude of 1.5 m."

</span><span>Waves on a pond are an example of which kind of wave?
</span>B. surface waves
Answer:
15 Joules
Explanation:
work = charge x potential difference
= 10 x 1.5
= 15
Answer:
The answer to your question is 1.35 Watts
Explanation:
Data
Work = W = 5 J
time = t = 3.7 s
Power = P = ?
Formula
Power is a rate in which work is done or energy is transferred over time
P = 
Substitution

Result
P = 1.35 W
