Answer:

The three methods used to treat water are

Filtration
Sedimentation
Distillation

Explanation:

These methods used include physical processes, biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light.

How is the gravitational force related to the distance between two objects?

babunello [35]

The gravitational force is related to the distance between two objects because it is inversely proportional to the square of the distance.

<h3>What is the gravitational force?</h3>

The gravitational force refers to the attraction between two different objects due to their masses.

This force (gravitational force) is fundamental for maintaining the distance of objects in the Universe.

In conclusion, the gravitational force is related to the distance between two objects because it is inversely proportional to the square of the distance.

Johanna makes the table below to organize her notes about centripetal forces. Which type of force should she place in the cell m

Valentin [98]

<u>Answer:</u> The correct answer is Option 2.

<u>Explanation:</u>

Centripetal force is defined as the force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.

Mathematically,

$F_c=\frac{mv^2}{r}$

Where,

$F_c$ = centripetal force

m = mass of the object

v = tangential velocity

r = radius of the path

From the above relation, X corresponds to the radius and Y corresponds to the tangential velocity.

Hence, the correct answer is option C.

The reactant concentration in a second-order reaction was 0.560 m after 115 s and 3.30×10−2 m after 735 s . what is the rate con

Aloiza [94]

Use the formula for second order reaction:

$\frac{1}{C} = \frac{1}{C_0} + kt$

C = concentration at time t
C0 = initial conc.
k = rate constant
t = time

1st equation : $\frac{1}{0.56} = \frac{1}{C_0} + 115k$

2nd Equation: $\frac{1}{0.033} = \frac{1}{C_0} + 735k$

Find $\frac{1}{C_0}$ from 1st equation and put it in 2nd equation:

$\frac{1}{0.033} = \frac{1}{0.56} - 115k + 735k$

$\frac{1}{0.033} - \frac{1}{0.56} = 620k$

k = 0.046
