Why does a coin and a feather fall with different accelerations in the presence of air?
The structure of the feather makes it catch the air and fall more slowly than the coin. Refer to the related link for the Apollo 15 mission to the moon, which has no atmosphere, in which an astronaut drops a hammer and a feather at the same time.
Is there a link between the height the ball is dropped from and the height to which it bounces?
Yes. Under ideal circumstances - no air resistance, elastic collision (i.e., perfect bounce), the ball should bounce back to the same height from which it was dropped, due to conservation of energy. In practice, some energy is always lost, both due to air resistance and to a non-perfect bounce.
What is a rigid link?
A rigid link is a structural component that connects two parts of a mechanism or machine in such a way that the relative position between the two parts remains fixed. It does not allow for any movement or flexibility between the connected parts. Rigid links are commonly used in engineering and design to provide stability and precise motion control.
What is the link between the thickness of the wire and the current needed to melt a wire?
Well, I am also doing this same question and its all about resistance. Resistance is when the electrons flow around a circuit and they collide with ions. These electrons transfer energy to the ions, which consequently get hot and move more so the resistance increases :) So the thicker the wire is, the less resistance it would have because there are more choices of pathways for the electrons can take without colliding with the ions. Therefore less resistance, more current needed to melt the wire. So the thicker the wire is, the more current is needed to melt it
Can radiation cause costochondritis?
There is no direct link between radiation exposure and costochondritis. Costochondritis is typically caused by inflammation in the cartilage that connects the ribs to the breastbone. However, radiation therapy can sometimes lead to inflammation in the chest area, which may present similar symptoms to costochondritis.
What is the link or bridge between negative and positive area called?
The link or bridge between negative and positive area is called a circuit
What is the difference between DC and AC resistance?
AC resistance should NOT be confused with IMPEDANCE or REACTANCE.When AC flows through a conductor, it tends to flow towards the surface of that conductor due to a phenomenon called the 'skin effect'. The skin effect, therefore, acts to reduce the effective cross-sectional area of the conductor. Since resistance is inversely-proportional to cross-sectional area, the result is an elevated value of resistance compared with that to DC current. This is called AC RESISTANCE, and it increases with frequency. At mains frequencies (50/60 Hz), AC resistance is not dramatically higher than DC resistance but the difference becomes significant at high frequencies.Read more in the Related link shown below this answer.
How surface area affects heat loss?
Increasing the Surface Area increases the heat loss. You will find a nice example in the related question link below.
What is the link between the uneven heating of Earths surface and air movement?
Wind
Formula for total area of cylinder?

What is the surface area formula of a square pyramid?
This is a popular topic, discussed in many places on the web. The attached link is one place that I like. If you want to look for others just google for surface area square pyramid.

What is the surface area of a square pyramid with a slant height of 14 cm and a base of 5 cm?
An online calculator [see Link below] gives me:Lateral Area (total area of the triangular sides) = 137.75 cm2Total surface area including base of 25 cm2 = 162.75 cm2
What is the link between the length width and area?
The area is the product of the length of a thing times its width. l x w = A
What is the formula for the lateral surface area of a cone?
Lateral surface area of a coner and l are the radius and slant height, respectively.A very quick "google" showspi x r x lreference: See related link below forthe reference
What do surface area and the rate something dissolve have in common?
The more surface area of a solute is exposed to a solvent, the more quickly the solvent can act on the solute, dissociating it if it's ionic. This is why finely grained salt dissolves much more quickly than a large clump of salt.
What is the surface area of a sphere with radius 4 feet?
Your sphere will have a surface area of about 201 square feet. The formula for finding the surface area (As) of a sphere is 4 times pi times the radius (r) squared, or this: As = 4 x pi x r2 That's As = 4 x 3.14 x 42 = 201.0619298 square feet. A link can be found for more information.
