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
Answer:
A(yellow) = 52
Explanation:
A(yellow) = A(total) - A(red)
= 11×6 - 7×2
= 66 - 14
= 52
p = latm
t = 273.15K
R= 0.08206 L atm mol K
75.0g02
16.00 (O₂) = 4.6875mol mol
9
Ideal gas law: PV = nRT, solve for volume: V = nRT P
V =
4.6875mol 0.08206 L-atm mol. K · 273.15K
V = 105L
latm
A characteristic for a movie or book could be how good or bad the plot/story is. You can even get more into detail for movies. Such as, "How was the acting? When the character was sad did you really feel their expressions?" Or so on like that haha. For books, it could be about it's pattern of writing or such, "alliterations, stressed patterens etc. Hope I helped lol.
