Photosynthesis is the process by which plants and other things make food. It is a chemical process that uses sunlight to turn carbon dioxide into sugars that the cell can use as energy. As well as plants, many kinds of algae, protists and bacteria use it to get food.

I believe you are correct, it is B: Diagnostic Services.

Diagnostic services are services like the staff at hospitals and the people who run machines that are related to medical needs.

You buy a magnifying glass at the store. The lens in the magnifying glass is a double convex lens, a lens with two convex curved

Leokris [45]

Answer:

30 cm

Explanation:

f = Focal length = 25 cm

R = Radius of curvature (both sides are equal)

$\mu$ = Refractive index of lens = 1.6

The lens maker formula is given by

$\frac{1}{f}=(\mu-1)(\frac{1}{R_1}-\frac{1}{R_2})\\\Rightarrow \frac{1}{f}=(\mu-1)(\frac{1}{R}-\frac{1}{-R})$ minus sign because it is on the other side

$\\\Rightarrow \frac{1}{f}=(\mu-1)\frac{2}{R}\\\Rightarrow R=2(\mu-1)f\\\Rightarrow R=2(1.6-1)\times 25\\\Rightarrow R=30\ cm$

The radius of curvature of the glass surface is 30 cm

what is the vapor pressure of water if the total vapor pressure is 1.5 atm and the pressure of oxygen is 0.2 atm?

andreyandreev [35.5K]

Since the total pressure of each gas is the sum of the partial pressures of all the individual gases, the vapor pressure of oxygen is 1.3 atm.

From Dalton's law of partial pressure, the total pressure is the sum of the individual partial pressures of the gases;

PT = PA + PB + PC + --------

Given that;

Vapor pressure of oxygen = 0.2 atm

Total pressure = 1.5 atm

Vapor pressure of oxygen = ?

Partial pressure of oxygen = 1.5 atm - 0.2 atm = 1.3 atm

The vapor pressure of oxygen is 1.3 atm.
