Answer:To ensure significant dialogue which will guarantee that the needed Products meets specifications
It will help to develop a better Operational model for the users.
Explanation: The design phase is one of the most critical phase in product development,it is in this phase that the product structure, contents and specifications are put into action. It is necessary that the end users have a significant time to dialogue with the project or product development team to guarantee that the end product meets specifications.
It is also necessary to spent adequate time in order to make the product user friendly (easy to operate and maintain).
Dimensional Formula of Density
The dimensional formula of density is given by,
[M1 L-3 T0]
Where,
M = Mass
L = Length
T = Time
Derivation
Density (ρ) = Mass × Volume-1 . . . . . (1)
The dimensional formula of volume = [M0 L3 T0] . . . . (2)
And, the dimensional formula of mass = [M1 L0 T0] . . . . (3)
On substituting equation (2) and (3) in equation (1) we get,
Density = Mass × Volume-1
Or, (ρ) = [M1 L0 T0] × [M0 L3 T0]-1 = [M1 L-3 T0]
Therefore, density is dimensionally represented as [M1 L-3 T0].

Aluminum has 3 valence electrons.
<span>You can figure out the valence electrons by looking at its group number. Aluminum is in group 3, so it has 3 valence electrons.

An astronomical unit is the measure of the center of the Earth to the center of the sun.
Because our solar system is so vast, using mere miles is ridiculous, because they are too small to be helpful and the numbers will be in the billions. Astronomical units make it easier to think in small amounts.
Hope this helps :)
