The bird in picture A flies with her wings backwards, minimising the contact surface with the wind and creating less resistance. The bird in picture B flies with her wings in the wind direction, creating much more resistance. The same phenomenon makes a crumpled piece of paper fall faster than an open sheet of paper, which has more surface and more resistance.
Remember the physical principle: The larger the surface of contact with air/wind, the more resistance (force) is created.

Gravity is applied onto both balls equally, and the vertical distance they ought to pass is identical. The time needed for both balls to hit the ground is similar, regardless of the horizontal velocity component.
Therefore, it can be deduced that both balls will hit the ground at the same time.
Remember the physical principle: When an object falls under gravity’s influence, its vertical velocity does not depend on the horizontal velocity.

Kettle B is higher and has a larger volume and initially seems as if it can contain more water. However, the kettle can only contain water to the height of the spout before it starts pouring out.

The spout at kettle B is shorter, and the total water height can be lower than in kettle A.

Wire B. Because it is carrying bulky portion of the stick.

Because A will make full grip to Drive the Screw.
