Kaylis [27]

<em>Answer:</em>

Thrust and Lift.

<em>Method:</em>

There are 4 forces acting upon a plane while it is moving. Drag (The air friction while it's in the air), Lift (Generated by the wings (The upward force), Weight (How heavy the plane is), and finally, Thrust (Generated by the engines which moves the plane/wings through the air generating lift). If there is enough air going over the wing at a high enough speed, and Thrust, and Lift overcome the other two forces keeping the plane on the ground, it can fly. The air pressure under the wing is higher than over the wing - If you have ever ran you hand under the water keeping it flat, you may notice it going up, those are basically the same forces, but under water.

How does the pressure under the wing affect the lift?

The difference of air pressure over the wing (which is less), which also means less force bringing the plane down. The air pressure under the wing is higher, putting pressure on the wing moving it up. A wing is designed to make the air travel a longer distance over the wing than under the wing creating the air pressure. The engines just enforce that process.

Which experiment is more likely to be reliable, and why ?
tigry1 [53]
Since there’s nothing here other than what you’ve asked i’ll guess, an experiment that is more likely to be reliable will not use the first values it gets, will be done multiple times and the values will be close in number

If a disease strikes the snake population in the food chain shown, what will be the initial effect on the populations of hawks a
Ilya [14]

Answer:

The hawk population will drop while the rabbit population will rise.

Explanation:

With the way the pyramid is structured, it shows that the rabbits eat grass, snakes eat the rabbits, and hawks eat the snakes. If the snakes are gone, the hawks will lose a food source, and their population will drop. Also, the rabbit population will rise, because the snakes eat the rabbits, and if the snakes are gone, they won't have any predators.

elena55 [62]

Out of the following give choices;

a. All DNA strands contained only the heavy nitrogen isotope.

b. Half of the DNA strands contained only the light nitrogen isotope.

c. All DNA strands contained both heavy and light nitrogen isotopes.

d. All DNA strands contained only the lighter nitrogen isotope.

The answer is b. Meselson–Stahl experiment demonstrated the semi-conservative model of DNA replication. When DNA is replicated, one strand of the new double helix strand is the parent's strand while the other is the newly synthesized one. This made the semiconservative model stand out over the other two, dispersive and conservative models.
