Troyanec [42]

Answer:

i)20369 photons

ii) 40 ps

Explanation:

Momentum of one Sodium atom:

P=m*v =600m/s*23amu*\frac{1 kg}{6.02*10^{23}amu}\\P=2.29*10^{-23}kgm/s

In other to stop it, it must absorb the same momentum in photons:

P=2.29*10^{-23}kgm/s=n_{photons}*\frac{h_{planck}}{\lambda}\\=n*\frac{6.63*10^{-34}}{589*10^{-9}} \\==>n=20369 photons

Now, for the minimun time, we use the speed of light and the wavelength. For the n photons:

t=n*T=n*\frac{\lambda}{c} =20369*\frac{589nm}{3*10^{8}m/s}=4*10^{-11} second=40 ps

Oxana [17]

Answer:

She was obese and had a diet high in salt intake.

Explanation:

higher blood pressure is condition known as hypertension which is the main cause of many heart problems which can be life threatening. In obese people. high level of fats inside the blood vessels which can cause blockage inside and can lead to heart problems.

high concentration of salts intake also disturbs the salts concentration in the blood vessels. The disturbance in salt concentration is the function of the kidney to remove it. the increase concentration also  cause increase in blood pressure which leads to hypertension.
