what is Maximum possible products?

Although Minimum Viable Product strategies are effective for startups, they presuppose you have no limitations. However, in an MPP universe, your limitations serve to focus you rather than to thwart you. Instead than conceptualizing ideas for the future, they require you to consider how well you can meet your clients' wants inside a specific situation that now exists.

Photobox will introduce countless new product lines that are only modifications of current products. For instance, a bowl could be printed as a dog bowl or a cereal dish for kids. The tech stack doesn't need to be altered, and customization yields the highest return on investment for the product.

For the absorbance of the solution in a 1.00 cm cell at 500 nm is mathematically given as

A’ = 0.16138

<h3>What is the absorbance of the solution in a 1.00 cm cell at 500 nm?</h3>

Absorbance (A) 2 – log (%T) = 2 – log (15.6) = 0.8069

Generally, the equation for the Beer’s law is mathematically given as

A = ε*c*l

0.8069 = ε*c*(5.00 )

ε*c = 0.16138 cm-1

then for when ε*c is constant

l’ = 1.00

A’ = (0.16138 cm-1)*(1.00 cm)

A’ = 0.16138

In conclusion, the absorbance of the solution in a 1.00 cm cell at 500 nm is

A’ = 0.16138
