Answer:
In converging mirrors light rays at the focus, while In diverging mirror it diverges the rays. Converging mirrors have positive focal length while Diverging mirrors have negative focal length. Converging mirrors form real,inverted and erect image while Diverging mirrors form erect images.
The density of gold is 19.3 g/cm³
Ag= silver
Au= gold.
density (Ag)=10.5 g/cm³.
density (Au)=19.3 g/cm³
We have to calculate the mass of 5 cm³ silver:
10.5 g---------------------1 cm³
x--------------------------- 5 cm³
x=(10.5 g * 5 cm³) / 1cm³ ≈52.5 g
And we have to calculate the mass of 5 g gold.
19.3 g------------------------1 cm³
x-------------------------------5 cm³
x=(19.3 g * 5 cm³) / 1cm³≈96.5 g
Then 5 cm³ silver are 52.5 g of mass, and 5 cm³ gold are 96.5 g of mass, therefore, gold would have a greater mass than silver.
answer:5 cm³ gold would have a greater mass than 5 cm³ silver.
