Answer:

The three quantized particles are:

1. Electrons

2. Protons

3. Neutrons

Explanation:

Quantization can be defined as the conversion of a continuous quantity into discrete set of values.

It can also be defined as the concept which says that the particles exist as the smallest finite and discrete value known as quanta which not be divided further.

The three particles include:

1. The electron bound inside an atom have quantized momentum and energy.

2. The proton bound in the inside of a nucleus has energy in the quantized form only.

3. Also the nucleus bound neutron is also a quantized particle.

A coil with an inductance of 2.3 H and a resistance of 14 Ω is suddenly connected to an ideal battery with ε = 100 V. At 0.13 s

klemol [59]

Given Information:

Resistance = R = 14 Ω

Inductance = L = 2.3 H

voltage = V = 100 V

time = t = 0.13 s

Required Information:

(a) energy is being stored in the magnetic field

(b) thermal energy is appearing in the resistance

Answer:

(a) energy is being stored in the magnetic field ≈ 219 watts

(b) thermal energy is appearing in the resistance ≈ 267 watts

Explanation:

The energy stored in the inductor is given by

$U = \frac{1}{2} Li^{2}$

The rate at which the energy is being stored in the inductor is given by

$\frac{dU}{dt} = Li\frac{di}{dt} \: \: \: \: eq. 1$

The current through the RL circuit is given by

$i = \frac{V}{R} (1-e^{-\frac{t}{ \tau} })$

Where τ is the the time constant and is given by

$\tau = \frac{L}{R}\\ \tau = \frac{2.3}{14}\\ \tau = 0.16$

$i = \frac{110}{14} (1-e^{-\frac{t}{ 0.16} })\\i = 7.86(1-e^{-6.25t})\\\frac{di}{dt} = 49.125e^{-6.25t}$

Therefore, eq. 1 becomes

$\frac{dU}{dt} = (2.3)(7.86(1-e^{-6.25t}))(49.125e^{-6.25t})$

At t = 0.13 seconds

$\frac{dU}{dt} = (2.3) (4.37) (21.8)\\\frac{dU}{dt} = 219.11 \: watts$

(b) thermal energy is appearing in the resistance

The thermal energy is given by

$P = i^{2}R\\P = (7.86(1-e^{-6.25t}))^{2} \cdot 14\\P = (4.37)^{2}\cdot 14\\P = 267.35 \: watts$

The energy delivered by battery is

$P = Vi\\P = 110\cdot 4.37\\P = 481 \: watts$

describe how acceleration and velocity are related and specify if these are scalar and vector quantities

vitfil [10]

Velocity is the rate of change in distance over change in time, this can be written as:

v = Δd / Δt

While acceleration is the rate of change in velocity over change in time, this is written as:

a = Δv / Δt

<span>Both quantities are vector quantities because negative values means that the acceleration or velocity is acting on the opposite direction.</span>

What would happen if I removed the battery from the circuit?

ira [324]

Answer:

The current would stop

Explanation:

Electric currents are interesting because they carry little to no momentum. As soon as you remove a power source, the whole current halts.

The Kinetic Molecular Theory helps explain relationships between:

Aleks [24]

The correct answer is<span> gases, energy, temperature, phases

Gravity and nuclear forces are not encompassed in the kinetic molecular theory as it deals with movement and behavior of gas molecules. It does not include their conversion to other types of energy or anything similar. </span>

Why is friction useful between your feet and the ground?

mixer [17]

Answer:

It allows you to walk faster.

Explanation:

It is the same force that allows you to accelerate forward when you run. Your planted foot can grip the ground and push backward, which causes the ground to push forward on your foot. We call this grip type of friction, where the surfaces are prevented from slipping across each other, a static frictional force.
