The first one with the big plus in the middle and negatively charged electrons around.

Explanation:

The first image with the plus sign in the middle and negatively charged electrons around it shows how J.J. Thomson envisioned the atom.

J.J. Thomson proposed the "plum pudding" model of the atom. This model suggested that atoms were composed of a positively charged "pudding" with negatively charged electrons embedded within it.

1. Thomson conducted experiments with cathode rays, which are streams of negatively charged particles emitted from cathodes in vacuum tubes. Through his experiments, Thomson discovered that cathode rays were composed of negatively charged particles, which he named electrons. Based on his observations, Thomson proposed the "plum pudding" model, also known as the "raisin bread" model.

According to this model, atoms were made up of a positively charged substance, like a pudding, with negatively charged electrons scattered throughout it, like raisins in bread. Thomson suggested that the positive charge was evenly distributed throughout the atom, creating a uniform positive charge in the "pudding." This model was a significant departure from the previous understanding of the atom as an indivisible, homogeneous sphere.

Thomson's plum pudding model provided an early depiction of atomic structure, showing that atoms were not indivisible but composed of smaller subatomic particles. However, later experiments, particularly those conducted by Ernest Rutherford, led to the discovery of the atomic nucleus, which necessitated the revision of Thomson's model.

Tangential speed vT, for the stallite that orbits the earth from a distance 3R is compared by  [tex]\bold {(vT)= \dfrac {(v0)}{3}}[/tex].

Given here,

Vo - Speed  

R - Distance of center of the earth

Fo - Force exerted on satellite

vT - Tangential speed

For satelite, Gravitational force (Fg)is equal to the centripetal force(Fc),

Fg = Fc = Fo

[tex]\bold {\dfrac {GMm}{R^2} = \dfrac {m(v0)^2}R}[/tex]

GM = (v0)²R.....................  (1)

Since, For satellite R = 3R

Thus,

[tex]\bold {\dfrac {GMm}{3R^2} = \dfrac {m(v0)^2}{3R}}[/tex]

[tex]\bold {\dfrac {GMm}{3R^2} = \dfrac {m(vT)^2}{3R}}\\\\\bold {\dfrac {GM}{27 R} = \dfrac {(vT)^2}{3R}}\\\\\bold {GM = \dfrac {27 R \times (vT)^2}{3R}}\\\\\bold {{GM}= 9 R \times (vT)^2}\\[/tex].........(2)

From equation 1 and 2,

(v0)²R = 9(vT)²R

Divide through R and then 9, we get

[tex]\bold {(vT)^2 = \dfrac {(v0)^2}{9}}[/tex]

Take the square root,

[tex]\bold {(vT)= \dfrac {(v0)}{3}}[/tex]

Answer:

50 N

Explanation:

We are given;

Spring constant; K = 20N/cm

Extension; Δx = 2.5 cm

We want to find the load which is the force. This is gotten from the equation;

F = k•Δx

F = 20 × 2.5

F = 50 N

Therefore the load needed is 50 N.

Answer:

A. The brightness of the bulb

Explanation:

An electric current through a circuit turns the lights bulb on. the strength of the current created by the generator will be indicated by the brightness of the bulb because in a closed circuit, the bulb is the only object that is representing that, circuit is properly placed and when bulb lights up only when electrical energy is generated.

More electrical energy generated through the generator means the brighter the bulb glow.

Hence, the correct answer is "A. The brightness of the bulb".

Explanation:

The acceleration of the scooter is 2.5 m/s

Answer:

Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. ... So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.

Answer:

W = 7056  J

Explanation:

Given that,

Mass of a load, m = 60 kg

Distance moved, d = 12 m

We need to find the amount of work. The work done by an object is given by :

W = Fd

So,

W = mg×d

W = 60 kg × 9.8 m/s²×12 m

W = 7056  J

So, the amount of work done is 7056  J.

Answer:

A)  C = 4.425 10⁻¹³ F,  B) Q = 6.31 10⁻¹¹ C,  C)  E = 8.9 10⁴ N / C,  

D)  u_{E} = 3.19 10⁻⁹ J

Explanation:

Part A. Capacitance is

           C = ε₀ A / d

in this case distance is d = 0.800 cm = 0.800 10⁻² m and the area of ​​the plates is x = 0.200 cm= 0.2 10⁻² m, all the quantities must be in the SI system for the result to be in Farads

           A = x²

           A = (0.2 10⁻²)²

           A = 4 10⁻⁶ m

let's calculate

          C = 8.85 10⁻¹² 4 10⁻⁶ / 0.8 10⁻²

          C = 44.25 10⁻¹⁴ F

          C = 4.425 10⁻¹³ F

Part B. The charge on each plate is

          Q = C ΔV

           Q = 4.425 10⁻¹³ 120

           Q = 6.31 10⁻¹¹ C

Part C. the electric field of a plate is

           E = σ / 2ε₀

where the charge density is

            σ = Q / A

we substitute

             E =[tex]\frac{Q}{ 2\epsilon_o A}[/tex]

let's calculate

             E = [tex]\frac{6.31^{-11} }{ 2 \ 8.85^{-12} \ 4^{-6} }[/tex]

             E = 8.9 10⁴ N / C

Part D. stored energy

              [tex]u_{E}[/tex] = ½ C V²

               u_{E} = ½ 4.425 10⁻¹³ 120²

Have a wonderful day!

Answer:

Im late. A D and E

Explanation:

The factors that affect an object's gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in. The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Dropping a can from a higher elevation  affects greater impact compare to  dropping a can from a lower elevation.

Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases.

If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised.

Potential energy is a system attribute, not a property of a single body or particle.

The potential energy of the can on higher elevation is greater than the potential energy of the can on  lower elevation. That is why, dropping a can from a higher elevation  affects greater impact compare to  dropping a can from a lower elevation.

Have a wonderful weekend!

If we want to convert the density of the silicon from  2.33 gram/ centimeter3 to kilogram /meter3 unit we have to perform the operation

(1 kilogram/ 10³ grams) ×(1 centimeter/10⁻² meters)×(1 centimeter/10⁻² meters)×(1 centimeter/10⁻² meters)

Therefore the correct answer is option B.

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

As given in the problem we have to convert the density of the silicon from  2.33 gram/ centimeter3 to kilogram /meter3 unit

1 kilograms = 1000 grams

1 meter = 100 cm

2.33 gram/ centimeter3 = 2.33×10 ⁻³kilogram / 10 ⁻⁶meter3 unit

                                       = 2.33×10³kilogram / 10 ⁻⁶meter3 unit
