Question 1

Chemistry

Bumek [7]3 years ago

Answer:

the average kinetic energy will double as well

Explanation:

According to the kinetic molecular theory of gases, the average kinetic energy of the particles in a substance is directly proportional to the absolute temperature of the gas (in Kelvin).

Mathematically:

KE=\frac{3}{2}kT

where

KE is the average kinetic energy of the particles in a gas

k is the Boltzmann constant

T is the absolute temperature of the gas

From the equation, we see that

KE\propto T

In this problem, the absolute temperature of the gas is doubled, so the new temperature is

T'=2T

Therefore, the new kinetic energy of the molecules will be

KE'\propto T' = 2T \propto 2KE

So, the average kinetic energy will double as well.

There are three factors in which natural selection occurs. Select one statement from the list below that is a true statement abo
azamat

Answer: There is no list in your question. But the three factors in which natural selection occurs are:

1. A struggle for existence,

2. Variation and

3. Inheritance

Explanation:

Darwin’s theory of natural selection is the way in which organisms change overtime.

These changes allow organisms to become better adapted to their environment and increase their chances for survival.

The three major factors through which natural selection occurs are:

1. A struggle for existence,

2. Variation and

3. Inheritance

Darwin’s theory of natural selection will occur if the three conditions above are met and unless these factors are in place, natural selection will not occur.

Position (m)
Alex777 [14]

Option C. The object is returning to the start at a constant speed.

<h3>Data points of the Position vs Time graph</h3>

The following data points will be used to determine the motion of the object.

<u>Position               Time</u>

12                          4

10                          6

2                            8

0                           10

From the data above, the position of the object is decreasing towards zero or start point.

Thus, the object is returning to the start at a constant speed.
