There’s nothing to answer so I can’t help
Answer:
the buoyant force F will be 0.84 N
Explanation:
Assuming that a person has the density of water , then its volume could be calculated through
V= m/ρ , where m= mass of the person , ρ= density of water
then
V= m/ρ = 70 kg/ 1000 kg/m³ = 0.07 m³
then the buoyant force will be equal to the mass of displaced air in the volume V.
if we assume that the density of air in the atmosphere is ρa=1.225 kg/m³ then the buoyant force F will be
F= ρa*V*g = 0.07 m³*1.225 kg/m³ *9.8 m/s² =0.84 N
<span>Youll need to use Wiens Displacement Law:\[T=\frac{ 2.8978*10^{-3}m∙K }{ \lambda _{\max} }\]Note that the units of the constant are meter∙Kelvin, so youll need to convert 350nm to meters.</span>
Answer:
Size is not considered a physical property because it is not measurable with concrete data, but a compound of height, weight and volume, which are physical properties by their own.
A physical property is, according to an initial understanding, an individual property, that is, which is linked in particular to any substance.
A physical property has the characteristic of being able to be measured or observed without affecting the composition or integrity of the respective substance. Some examples of physical properties are mass and volume.
