Answer:
if we measure the change in height of the gas within the had and obtain a straight line in relation to the depth we can conclude that the air complies with Boye's law.
Explanation:
The air in the tube can be considered an ideal gas,
P V = nR T
In that case we have the tube in the air where the pressure is P1 = P_atm, then we introduce the tube to the water to a depth H
For pressure the open end of the tube is
P₂ = P_atm + ρ g H
Let's write the gas equation for the colon
P₁ V₁ = P₂ V₂
P_atm V₁ = (P_atm + ρ g H) V₂
V₂ = V₁ P_atm / (P_atm + ρ g h)
If the air obeys Boyle's law e; volume within the had must decrease due to the increase in pressure, if we measure the change in height of the gas within the had and obtain a straight line in relation to the depth we can conclude that the air complies with Boye's law.
The main assumption is that the temperature during the experiment does not change
His average speed is (35m/45s) = 7/9 meters per second.
His average velocity is (30m W + 5m E) / (45s) = 25 m/s West .
Diagram A will result in the movement of the block to the left as a result of the forces.
<h3>What is Force?</h3>
This is referred to an influence which is capable of changing the motion of an object.
Diagram A has equal upward and downward force and left side which is 60N is higher than the right side which has 20N. The block will therefore move to the left.

Answer:
605 J
Explanation:
Efficiency = work out / work in
0.78 = W / 775 J
W = 605 J
The best answer is d - while comparing the data with the hypothesis. The scientific method defines the correct steps as:
1. observation - use of the five senses to learn about something.
2. Question - where you raise questions based on your observation.
3. Hypothesis - a prediction or guess of what the answer to the question is.
4. Method - point where you test the hypothesis by carrying out an experiment.
5. Results / data - this is what happened after each step of the experiment.
6. Conclusion - where the results of the experiment are discussed and it is summarized if the prediction was true or not, based on data from the results.
