What is the kinetic theory of matter? How does it relate to the motion of molecules?
Charra [1.4K]

Answer:

Explanation:

Kinetic energy is energy that an object has because of its motion. The Kinetic Molecular Theory explains the forces between molecules and the energy that they possess. This theory is based on three theories about matter. Matter is composed of small particles (atoms, molecules, and ions).

A table tennis ball with a mass of 0.003kg and soccer with a mass of 0.43 kg. are both set in motion at 16 m"s. Calculate and co
Aliun [14]

Let us first know the given: Tennis ball has a mass of 0.003 kg, Soccer ball has a mass of 0.43 kg. Having the same velocity at 16 m/s. First the equation for momentum is P=MV P=Momentum M=Mass V=Velocity. Now let us have the solution for the momentum of tennis ball. Pt=0.003 x 16 m/s= (    kg-m/s ) I use the subscript "t" for tennis.  Momentum of Soccer ball Ps= 0.43 x 13m/s = (      km-m/s). If we going to compare the momentum of both balls, the heavier object will surely have a greater momentum because it has a larger mass, unless otherwise  the tennis ball with a lesser mass will have a greater velocity to be equal or greater than the momentum of a soccer ball.

A coil is connected in series with a 12.6 kΩ resistor. An ideal 65.2 V battery is applied across the two devices, and the curren
ivolga24 [154]

To solve the problem, start by applying the concepts related to current in an RL circuit. The current is defined exponentially and using Ohm's law we can put the initial current in terms of the voltage and resistance. Consecutively with the calculated time constant we can find the respective inductance. For the second part we will apply the electrical potential energy connectors to find the amount of stored energy.

PART A)

i = i_0 (1-e^{-t/T})

i = (V/R)(1-e^{-t/T})

0.00402 = (65.2/12600)(1-e^{-0.00402/T})

T = 0.002679s

T = L/R

Inductance can be defined then,

L = RT

L = (12600)(0.002679)

L = 33.75H

PART B) Now the energy is given under the terms:

E = \frac{1}{2}Li^2

E = \frac{1}{2} (33.75)(0.00402)^2

E = 0.0002727J

Therefore the energy stored in the coil at this same moment is 0.0002727J

Mrac [35]

The gravitational force I’d experience while I am floating outside the ISS will be 4.47 × 10⁻¹⁵ N.

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

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

\rm F=G\frac{mM_E}{R^2} \\\\ \rm F=6.67 \times 10^{-34}\times \frac{60 \times 5.97 \times 10^{24}}{(6731)^2} \\\\ F=4.47 \times 10^{-15} \ N

Hence, the gravitational force I’d experience while I am floating outside the ISS will be 4.47 × 10⁻¹⁵ N.
