Even after reading the question, I don't understand it.
The speed of light is 299,792,458 meters per second, and that is the "speed limit" of the universe. Nothing moves faster. (Not even tachyons.)

<span>tachyons are a lot faster than the speed of light </span>

Write a program that calculates the average of n integers. the program should prompt the user to enter the value for n and then

Muscles use force to move objects. When using a ramp to do work, would your muscles use more force or less force?

White raven [17]

Less because the ramp is letting off force but i does depend on the way you are going on the ramp

An element is highly conductive, highly reactive, soft, and lustrous. The element most likely belongs to which group?(1 point)

UkoKoshka [18]

An element which is highly conductive, highly reactive, soft, and lustrous is most likely an alkali metal.

Alkali metals are in group 1 of the Periodic table which means that they have only a single valence electron.

This causes them to be soft and highly reactive because:

The single valance electron leads to weak bonds amongst the element's atoms which makes them soft
The elements want to lose the single valance electron so as to become stable so they will react with other elements to give away the electron.

Examples of alkali electrons include:
