An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it.
The many forms of arch are classified into three categories: circular, pointed, and parabolic. Arches can also be configured to produce vaults and arcades.
<h3>Rounded/circular</h3>
Rounded/circular arches were commonly used for ancient arches that were constructed of heavy masonry. Ancient Roman builders relied heavily on the rounded arch to span great lengths.
<h3>The parabolic</h3>
The parabolic arch employs the principle that when weight is uniformly applied to an arch, the internal compression resulting from that weight will follow a parabolic profile. Of all forms of arch, the parabolic arch produces the most thrust at the base yet can span the greatest distances.
Therefore, the parabolic arch is more structurally sound.

Answer: True
Explanation:
An archaic word is one that is old fashioned or no longer used contemporarily and that is what the word DOTH is.
In the past Doth was used to refer to the word DO in a present singular third person manner but it's use is no longer widespread.
For example, "She doth nothing wrong" in the present format would be, " She is doing nothing wrong".
Think of Einstein’s theory of general relativity. If a wide receiver making a catch collides in midair with the defender, the defenders often fair little better in these situations because they tend to run a little larger than receivers. But it is not a matter of force. Newton’s third law of motion (“to every action there is an equal and opposite reaction / the mutual actions of two bodies upon eachother are always equal and directed to contrary parts”) implies that this issue has to do with momentum, the product of mass and velocity. A force between two objects is an interaction that changes momentum. If the momentum of one increases, the momentum of the other will decrease by a substantial amount. All that is needed to be thought about is is the momentum right before the two come into contact and the momentum right after they stop interacting.
