According to the kinetic theory, all matter is composed of _______.
Answer:
According to the kinetic theory, all matter is composed of _______.
Explanation:
The Kinetic Theory of Matter states that matter is composed of a large number of small particles, individual atoms or molecules, that are in constant motion. Matter is made up of particles that are constantly moving. All particles have energy, but the energy depending on the temperature of which matter is in.
According to the kinetic theory, all matter is composed of large number of identical small molecules.
What is kinetic theory of gases?
A lot of the fundamental ideas of thermodynamics were established with the help of the kinetic theory of gases, a straightforward yet historically significant classical model of the thermodynamic behavior of gases.
According to the model, a gas is made up of numerous identical submicroscopic particles (atoms or molecules) that are all moving rapidly and randomly.
It is considered that they are substantially smaller in size than the particle spacing on average. Random elastic collisions between the particles and with the container's walls occur between the particles. The simplest form of the model only takes into account the interactions within the ideal gas.

Which is directly proportional to your weight on a planet's surface?
A. Only your mass
B. Only the mass of the planet
C. Your mass and the mass of the planet
D. The distance from the surface to the center of the planet
Answer: B. Only the mass of the planet
Explanation:
the confusion on the concepts of mass and weight arises from the fact that the acceleration due to gravity is more or less constant in any place on the Earth's surface, thus the weight of an object is directly proportional to its mass. hope it helps <3
A)What is the acceleration at 1 second?
Answer in units of m/s 2.
B) What is the velocity at 2 seconds?
Answer in units of m/s.
C) What is the position at 2 seconds?
Answer in units of m
Answer:
Acceleration at 1 second= 1.5m/s/s
Velocity at 2 seconds = 3m/s
Position at 2 seconds= 3 meters
Explanation:
s=1/2(v+u)t
S= displacement
V= final velocity
U= initial velocity
t= time
v= 3 m/s
u= 0 m/s
t= 2 seconds 3m/s/2=1.5m/s x2 s = 3 meters
how is the friction force produced
Explanation:
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

A bowling ball rolls off the edge of a flat roof at a velocity of 16 m/s. What is the actual speed of the ball one second later?
Answer:
The horizontal velocity is constant at 16 m/s.
After 1 sec since v = a t then 9.8 m/s^2 * 1 sec = 9.8 m/s for the vertical velocity
V = (Vx^2 + Vy^2)^1/2 = (16^2 + 9.8^2)^1/2 = 18.8 m/s

The weight of an object can be described as the pull, or force, of gravity on it. This force is given by the mass of the
object times the acceleration due to gravity, F=mg. The acceleration due to gravity, g, is a constant with a value of
9.81 m/s?. Calculate the weight due to gravity in Newtons of an object that is 4.69 lbs.
A)
0.217 N
B)
11.5 N
20.9 N
Х
D)
46.0 N
Answer:
The answer is 46.0089 N of weight
Explanation:
The answer is in the question
F=mg
reverse the question, mg=F
Plug in the values of mass (4.69) and gravity (9.81)
4.69(9.81)=F
F = 46.0089 (or D)

A cotton garment cannot keep us warm in winter as a woolen sweater can. Give
reason.
Answer:
Cotton clothes are thin and do not have space in which air can be trapped. Thus, cotton clothes do not prevent heat coming out of our body. Woollen clothes keep us warm during winter because wool is a poor conductor of heat and it has air trapped in between the fibres.
Explanation:
Answer:
woolen clothes in winter because woolen clothes gives us warmth. ... We should wear light colored clothes in summer because light coloured clothes keeps us cool as they insulate the heat. And cotton clothes makes us comfortable in summers and cotton clothes absorb the sweat which we get mostly in summers

Light enters water at an angle of incidence of 24 degrees and refractive index of 4/3.Calculate the angle of refraction
Explanation:
According to Snell's law :
Sin i / Sin r = refractive index
[tex]r = sin^{ - 1} ( \frac{sin \: i}{1.33} ) = sin^{ - 1} (0.3)[/tex]
[tex]angle \: of \: refraction = 17.45°[/tex]
Therefore, angle of refraction is less than angle of incidence because the light ray bends towards the normal when it travels from rarer to denser medium

An airplane accelerates with a constant rate of 3.0 m/s2
starting at a velocity of 21 m/s. If the final velocity is 60 m/s,
what is the displacement during this period?
Answer:527 m
Explanation:
The displacement or distance travelled by the airplane during the given period is 526.5m
Given the data in the question;
constant acceleration; [tex]a = 3.0m/s[/tex]
Initial velocity; [tex]u = 21m/s[/tex]
Final velocity; [tex]v = 60m/s[/tex]
Displacement or distance; [tex]s = ?[/tex]
To find the displacement or distance the plane has travelled during the given period, we use the Third Equation of Motion:
[tex]v^2 = u^2 + 2as[/tex]
Where v is the final velocity, u is the initial velocity, a is the acceleration and s is the displacement.
Lets make "s" the subject of the formula
[tex]s = \frac{v^2-u^2}{2a}[/tex]
We substitute our given values into the equation
[tex]s = \frac{(60m/s)^2 - (21m/s)^2}{2 \ *\ 3m/s^2} \\\\s = \frac{(3600m^2/s^2) - (441m^2/s^2)}{6m/s^2}\\\\s = \frac{3159m^2/s^2}{6m/s^2}\\\\s = 526.5m[/tex]
Therefore, The displacement or distance travelled by the airplane during the given period is 526.5m

What evidence shows galaxies are moving away from us?
speed
blue shift
red shift
changes in light
Answer:
Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. The concept is key to charting the universe's expansion.
Visible light is a spectrum of colors, which is clear to anyone who has looked at a rainbow. When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter hope this helps.
Explanation:
A thin spherical shell with radius R1 = 4.00 cm is concentric with a larger thin spherical shell with radius R2 = 6.00 cm . Both shells are made of insulating material. The smaller shell has charge q1=+6.00nC distributed uniformly over its surface, and the larger shell has charge q2=−9.00nC distributed uniformly over its surface. Take the electric potential to be zero at an infinite distance from both shells.
Answer:
The right response will be "450 volts".
Explanation:
The given values are:
R1 = 4.00 cm
R2 = 6.00 cm
q1 = +6.00 nC
q2 = −9.00 nC
As we know,
The potential difference between the two shell's difference will be:
⇒ [tex]\Delta V=K[(\frac{q1}{R1}+\frac{q2}{R2})-(\frac{q1}{R1} +(\frac{q2}{R2}))][/tex]
[tex]=K[\frac{q1}{R2}-\frac{q1}{R1} ][/tex]
On substituting the values, we get
[tex]=(9\times 10^9)[\frac{6\times 10^{-9}}{0.04}-\frac{6\times 10^{-9}}{0.06}][/tex]
Δ [tex]=450 \ volts[/tex]
