What is the best use of an atomic model to explain the charge of the particles in Thomason beans

1 answer:

5 0

An atom's negative particles are surrounded by positive matter, so the positive particles are easier to remove. Thomson's atom model is formed by positive and negative particles The positive particles are bigger than the negative，but the atom is still in equilibrium，this is possible because they have the same“density if you wanna call it like that。So，the properties of negative particles allow them to move free。On the other hand，bigger particles，don't have free moving like negative particles。That's why electrons（negative particles）are the definition of electricity，because they can move easily，although this movement depend on the material，metal are better to move in than wood or plastic.

What are the differences between balloon framing and platform framing? What are the advantages and disadvantages of each? Why ha

Licemer1 [7]

Answer:

Difference : Balloon framing go through from foundation to top floor while Platform do not

advantages and disadvantages

Balloon framing : It has less vertical shrinkage ( disadvantage )

platform framing : It has more vertical shrinkage and fire stops ( advantage )

platform framing : It is easier and safer to use

Reason for platform framing :

Due to these advantages Platform framing has become a better choice

Little added fire stopping is required in platform framing because of double tap plate present which can act as as a fire stop

Steel beam/ glue laminated wood beam is preferred at foundation level because wood beam under the ground will most likely shrink over time

Explanation:

Differences : Balloon framing a form of building houses using a special kind of timber construction its studs start from the foundation and go to all the way to the last floor while in Platform framing the studs are interrupted by floor platforms ( i.e. they do not go through like in Balloon framing )

advantages and disadvantages

Balloon framing : It has less vertical shrinkage ( disadvantage )

platform framing : It has more vertical shrinkage and fire stops ( advantage )

platform framing : It is easier and safer to use

A certain dielectric with a dielectric constant = 24 can withstand an electric field of 4 107 V/m. Suppose we want to use this d

mr_godi [17]

Answer:

Explanation:

Electric field E = 4 x 10⁷ V / m

Dielectric constant k = 24

capacitance of capacitor

C = kε₀ A / d

d = plate separation

A = plate area

C = .89 x 10⁻⁶

V / d = electric field

for minimum d , electric field will be maximum

V / d = 4 x 10⁷

1930 / d = 4 x 10⁷

d = 1930 / 4 x 10⁷

d = 482.5 x 10⁻⁷ m

= 48.25 x 10⁻⁶ m

C = kε₀ A / d

.89 x 10⁻⁶ = 24 ε₀ A / d

A = .89 x 10⁻⁶ X d / 24 ε₀

A = .89 x 10⁻⁶ X 48.25 x 10⁻⁶ / 24 x 8.85 x 10⁻¹²

= 42.9 / 212.4

= .2019 m²

You are designing a generator with a maximum emf 8.0 V. If the generator coil has 200 turns and a cross-sectional area of 0.030

shutvik [7]

Answer:

7.1 Hz

Explanation:

In a generator, the maximum induced emf is given by

$\epsilon= 2\pi NAB f$

where

N is the number of turns in the coil

A is the area of the coil

B is the magnetic field strength

f is the frequency

In this problem, we have

N = 200

$A=0.030 m^2$

$\epsilon=8.0 V$

B = 0.030 T

So we can re-arrange the equation to find the frequency of the generator:

$f=\frac{\epsilon}{2\pi NAB}=\frac{8.0 V}{2\pi (200)(0.030 m^2)(0.030 T)}=7.1 Hz$
