A biologist keeps a specimen of his favorite beetle embedded in a cube of polystyrene plastic. The hapless bug appears to be 2.0
Fofino [41]

Answer:

the beetle's actual distance beneath the surface, d = 3.2 cm

Explanation:

The refractive index for the plastic is about 1.60

For overhead viewing, the expression for refractive index is

n = actual depth / apparent depth

Rearrange for actual depth

actual depth d = n x apparent depth

d = 1.60 x 2.0 cm

d = 3.2 cm

the mass of piece of granite is 15.6g when it is suspended can a mass of 5.5g of water is displaced find the dencity of granite
Blababa [14]

Answer:

2836.36 kg/m³

Explanation:

Applying,

Densty of granite(D')/Density of water(D) = weight of granite(W')/weight of water displaced(W)

D'/D = W'/W................... Equation 1

Make D' the subject of the equation

D' = W'D/W............... Equation 2.

From the question,

Given: W' = mg = 9.8(15.6/1000) = 0.15288 N, W = 9.8(5.5/1000) = 0.0539 N, Constant: D = 1000 kg/m³

Substitute these values into equation 2

D' = 1000(0.15288)/0.0539

D' = 2836.36 kg/m³
