A platinum sphere with radius $0\mathrm{.}0179$ m is totally immersed in mercury.

The densities of platinum and mercury are $2\mathrm{.}14{10}^{4}k\frac{g}{m^3}$ and $1\mathrm{.}36{10}^{4}k\frac{g}{m^3},$ respectively.

What is the weight $W$ of the sphere?

$W=$

N

What is the buyoant force $B$ acting on the sphere?

$B=$

What is the sphere's apparent weight $W_{\text{a}\text{p}\text{p}}?$

$W_{\text{a}\text{p}\text{p}}=$
