Answer:
4.33 L
Explanation:
Step 1: Given data
Initial volume of the balloon (V₁): 3.00 L
Initial pressure of the balloon (P₁): 765 torr
Final volume of the balloon (V₂): ?
Final pressure of the balloon (P₂): 530 torr
Step 2: Calculate the final volume of the balloon
If we consider Helium to behave as an ideal gas, we can calculate the final volume of the balloon using Boyle's law.
Answer:
The modern understanding of an atom was developed by the quantum theory
Answer:
1. It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up
2. lift
In order for an aircraft to rise into the air, a force must be created that equals or exceeds the force of gravity. This force is called lift. In heavier-than-air craft, lift is created by the flow of air over an airfoil. The shape of an airfoil causes air to flow faster on top than on bottom.
3. Gravity and drag (air resistance, which is friction caused by air rubbing against the plane) try to pull the plane down and slow its speed. A plane must be built so that lift and thrust are stronger than the pull of gravity and drag by just the right amount.
4. If lift becomes greater than weight, then the plane will accelerate upward. If the weight is greater than the lift, then the plane will accelerate downward. When the thrust becomes greater than the drag, the plane will accelerate forward.
5.The 4 Forces of Flight. In level flight, lift equals weight and thrust equals drag when the plane flies at constant velocity. Maintaining a steady flight requires a balance, often described as an equilibrium of all the forces acting upon an airplane.
Thank you and please rate me as brainliest as it will help me to level up
Cells have lots of things to do. Some cells make the whole organism, so that one cell must do everything that organism needs to do to live. Other cells perform specific functions, so they must be designed to do that specific activity.
There you go :) just reword it and try make it into your own words like just switch some sentences around
