re that Bernoulli's principle is applicable? Bernoulli's principle can be used to explain the lift force on an airplane wing. How must an airplane's wing be designed to ensure that Bernoulli's principle is applicable? Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure. Airplane wings must be designed to ensure that air molecules are deflected downward after hitting the wing. Airplane wings must be designed to ensure that air molecules move more rapidly past the bottom surface of the wing, creating a region of higher pressure. Airplane wings must be designed to ensure that air molecules are deflected upward after hitting the wing. Airplane wings must be designed so that they are thick enough to ensure a significant pressure difference between the top and bottom surfaces of the wings.

Answer:

Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure.

Explanation:

Swiss physicist Daniel Bernoulli proposed a principle for fluid flow, which can be stated as follows: "If the speed of a fluid particle increases as it flows along a current line, the fluid pressure must decrease and vice versa".

This knowledge allows us to understand why airplanes are able to fly. In the upper part of the wing the air velocity is higher (the particles travel a greater distance at the same time), therefore, the pressure on the upper surface is less than on the lower surface, which ends up creating a holding force from below to up.

With this principle, we can say that the wings of the airplane must be designed to ensure that air molecules move more quickly over the upper surface of the wing, creating a region of less pressure.

Strike441 [17]

Answer:

This question can be answered by using conversation of energy.

K_1 + U_1 = K_2 + U_2

\frac{1}{2}mv_{0}^2 + mgh_1 = 0 + mgh_2

\frac{1}{2}(3)v_0^2 + (3)(9.8)(30) = (3)(9.8)(45)\\\frac{1}{2}(3)v_0^2 = 441\\v_0^2 = 294\\v_0 = 17.14 m/s

Explanation:

Note that we take K_2 = 0 because we are looking for the minimum initial speed for the penguin to reach the top of the second hill. Any other speed more than this will already be enough for him.

What is a sign of genetic mutation
ad-work [718]
A sign of genetic mutation is a missing finger or an extra limb of some sort. Also people who study the human genome can trace gene pairs that are not complete or mixed up which can  cause genetic mutations.
