Answer:
maybe it's because a bucket of water has more density than egg B
Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system. Mathematically can be written as,
Here,
v = speed of the exhaust gases measured relative to the rocket.
= Rate of change of mass with respect to time
Our values are given as,
Replacing we have that

Explanation:
Answer:
Which microphone captures a singer's low sounds the loudest?
Explanation:
Scientific questions are the basis of any scientific experiment. An observation is followed by a scientific question. In this question, scientists are investigating how well different microphones capture and record sounds by using tools that show how loud the high and low sounds are and a tool that shows how much noise is recorded along with the actual sounds.
Hence, a scientific question should be that which will cover the whole aspect of the investigation i.e. the question should contain a general scope of the problem. Hence, a scientific question that could be included in this investigation is:
Which microphone captures a singer's low sounds the loudest?
This is because this question contains every part being investigated i.e. How different microphones capture sounds and records them (whether low or high).
