Answer:
Returning passengers back safely to Earth
Explanation:
When two forces act on an object in opposite directions, the net force can be calculated by subtracting the two forces.
<u>Explanation:</u>
- The net/final force by subtracting the two given opposite forces as asked in the above question.
For example: If you keep a bottle on the table, the downward force subtracted from the upward force will be equal to the net force.
- If the net force equals zero then the objects will be balanced, otherwise unbalanced.
For example: In the tug of war when two forces are of different units the force with the greater strength will have an advantage, like if the team on the right is stronger than that of left than the rope will move towards the right.
The answer is A. Columb
Columb discovered a relationship between charge, their speration, and the force between the two charges in 1787
Answer:
158 mL
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 99.0 KPa
Initial volume (V₁) = 300 mL
Final pressure (P₂) = 188 KPa
Final volume (V₂) =?
The final volume of the gas can be obtained by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
99 × 300 = 188 × V₂
29700 = 188 × V₂
Divide both side by 188
V₂ = 29700 / 188
V₂ = 158 mL
Therefore, the final volume of the gas is 158 mL.
Louis Pasteur's experiment was A) <em>controlled</em>.
A scientist must change <em>only one variable at a time</em> to see if it is the one causing the observed change.
The scientist must keep all the other variables constant (i.e. <em>control </em>the variables)
