a. 2.56x104 kg/m3
b. 1.0x104 kg/m3
Di
c. 0.5x104 kg/m3

d. 2.14x104 kg/m3
IL:

d. 2.14 x 10⁻⁴ kg/m³

Explanation:

Density is defined as the mass of an object per unit volume occupied by that object. The formula of density is, therefore, given as follows:

where,

ρ = density of platinum band = ?

m = mass of platinum band = 3 x 10³ kg

V = Volume displaced by Platinum band = 1.4 x 10⁷ m³

Therefore,

Hence, the correct option is:

d. 2.14 x 10⁻⁴ kg/m³

from

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
