What is the maximum radiation pressure exerted by sunlight in space ( s = 1350 w/m 2) on a flat black surface? a. 2. 25 × 10−5 p

mel-nik [20]

The maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × $10^{-6}$ P a. So, the correct option is (b).

Radiation pressure is the name for the force electromagnetic wave particles exert on a surface. It is inversely related to the wave's speed. Given data

Solar constant ( S ) = 1350W / m ^2

Now, the radiaton pressure is given by

P = 2 S /c

where c is the speed of the light

P = 2 × 1350 /3 × 10 ^8

P = 9 × $10^{-6}$ P a

For a black surface, P = 4.5× $10^{-6}$ P a

Therefore, maximum radiation pressure exerted by sunlight in space on a flat black surface is 4.5 × $10^{-6}$ P a

Describe differences between conduction and convection give examples

nevsk [136]

Explanation:

Both conduction and convection are both forms of heat transfer from one place to another.

In conduction, there must be contact between two bodies for the process to take place but in convection, the matter moves to transfer heat.
Conduction mostly occurs in solid substances whereas convection occurs mostly in fluids.
Heat transfer in conduction is quite slow compared to convection which is much faster.

Example of conduction is heating of iron pot when cooking

Example of convection is the refrigerating system.

How many mL of 2M stock solution would I use to prepare 0.500 L of 0.1 M NaCl?

nordsb [41]

Answer:

25 mL

Explanation:

Step 1: Given data

Concentration of the concentrated solution (C₁): 2 M

Volume of the concentrated solution (V₁): ?

Concentration of the diluted solution (C₂): 0.1 M

Volume of the diluted solution (V₂): 0.500 L

Step 2: Calculate the volume of the concentrated NaCl solution

We will use the dilution rule.

C₁ × V₁ = C₂ × V₂

V₁ = C₂ × V₂ / C₁

V₁ = 0.1 M × 0.500 L / 2 M

V₁ = 0.025 L = 25 mL

Si 100 monedas tienen una masa total de 226.13g. Cual es la masa de una moneda

galben [10]

The mass of a coin : 2.2613 g

<h3>Further explanation </h3>

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

1. phrases

algebraic forms separated by arithmetic operations

consists of one phrase (monomial) to many phrases (polynomial)

2. variables

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

3. constants

is a fixed value, can be a number

4. arithmetic operations ⇒ +, - , : , x

<em>If 100 coins have a total mass of 226.13g. What is the mass of a coin</em>

We can make this statement in the form of an algebraic equation :

100 coins=226.13 g

then the mass of a coin :

$\tt \dfrac{1}{100}\times 226.13~g=2.2613~g$
