Sirius A has a luminosity of 26 LSun and a surface temperature of about 9400 K.What is its radius?

wlad13 [49]

Answer

Given,

Sirius A surface temperature,T = 9400 K

Sirius A luminosity,L = 26 L₀

L₀ is the luminosity of sun.

Radius of sun = 695700000 m

Temperature on sun surface = 5780 K

Luminous intensity is given by:-

$L=4 \pi R^{2} \sigma T^{4}$

Now

$\frac{L}{L_{0}}=\frac{4 \pi R^{2} \sigma T^{4}}{4 \pi R_{0}^{2} \sigma T_{0}^{4}}=26$

$\Rightarrow \frac{R^{2} T^{4}}{R_{0}^{2} T_{0}^{4}}=26$

$\Rightarrow R^{2}=26 \times \frac{R^{2} T_{0}^{4}}{T^{4}}=26 \times \frac{695700000^{2} \times 5780^{4}}{9400^{4}}$

$R=1341246640\ m=1.34 \times 10^{9}$

Water occupies two main fluid compartments within the body, the intracellular fluid compartment and the extracellular fluid comp

nadezda [96]

Answer:

C. Approx. Two thirds of the water is in the ICF compartment

Explanation:

The body cells are bathed in fluids internally and externally. The water inside the cells make up about 42% of the total body weight and is called the intracellular fluid (ICF). The rest of the fluid outside the cells is called extracellular fluid (ECF) and is separated from the intracellular fluid by a semipermeable membrane that surrounds the cell, and only allows fluid to flow in and out of the cells, but prevents unwanted molecules or materials from getting in.

How does and objects density determine whether the object will sink or float

kap26 [50]

Density means how much mass is concentrated in the given 3d space .thus the more the density the more mass is occupied in the less space.. and thus the objects with lesser density floats on the object with higher density
