Explain the Kinetic Theory of Matter and use an example from everyday life

Physics
1 answer:
abruzzese [7]3 years ago
3 0

Answer:

The Kinetic Theory of Matter or KTM as i will call it, states that every object is made of many many small particles (humans are made of sextillions of atoms), and that they are constantly moving and bumping each other. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.

An example would be Brownian Motion- the random movement of dust particles because of collisions with "air" molecules and how gases behave i.e. Boyle's, Charles', and Gay-Lussac's Laws.

Part of the solar radiation entering the atmosphere about ___ actually reaches the earth's surface
Dmitry [639]

Answer:

48%

Explanation:

The earth's temperature has to be stable and this is the reason for the presence of incoming and outgoing heat. Of the solar energy reaching the atmosphere, about 29% is bounced back as reflected radiation by clouds, snow and particles in the atmosphere, about 23% is absorbed by the atmosphere and about 48% actually gets to the earth surface.

Equality Properties

<u>Geometry</u>

  • Area of a Rectangle: A = lw

<u>Algebra I</u>

  • Exponential Property: w^n \cdot w^m = w^{n + m}

<u>Calculus</u>

Derivatives

Differentiating with respect to time

Basic Power Rule:

  • f(x) = cxⁿ
  • f’(x) = c·nxⁿ⁻¹

Explanation:

<u>Step 1: Define</u>

Area is A = lw

2w = l

w = 300 m

\frac{dw}{dt} = 24 \ m/year

<u>Step 2: Rewrite Equation</u>

  1. Substitute in <em>l</em>:                    A = (2w)w
  2. Multiply:                              A = 2w²

<u>Step 3: Differentiate</u>

<em>Differentiate the new area formula with respect to time.</em>

  1. Differentiate [Basic Power Rule]:                                                                   \frac{dA}{dt} = 2 \cdot 2w^{2-1}\frac{dw}{dt}
  2. Simplify:                                                                                                           \frac{dA}{dt} = 4w\frac{dw}{dt}

<u>Step 4: Find Rate</u>

<em>Use defined variables</em>

  1. Substitute:                    \frac{dA}{dt} = 4(300 \ m)(24 \ m/year)
  2. Multiply:                        \frac{dA}{dt} = (1200 \ m)(24 \ m/year)
  3. Multiply:                        \frac{dA}{dt} = 28800 \ m^2/year

a high speed train travels with an average speed of 250 km/h. the train travels for 2 hrs. how far does the train travel
steposvetlana [31]

Answer:

<h3>The answer is 500 km </h3>

Explanation:

The distance covered by an object given it's velocity and time taken can be found by using the formula

<h3>distance = average velocity × time</h3>

From the question

average speed = 250 km/h

time = 2 hrs

We have

distance = 250 × 2

We have the final answer as

<h3>500 km</h3>

Hope this helps you
