The average acceleration of the particle between 0 seconds and 2 seconds is 4 m/s², and it is constant. From 2 seconds to 4 seconds, the particle experiences no acceleration as it moves at a constant velocity.

The question asks about the average acceleration of a particle between 0 seconds and 4 seconds. Since the acceleration is constant and equal to 4 m/s² along the x-direction, this value itself represents the average acceleration over the given time interval. There's no need to perform any additional calculations if the acceleration doesn't change with time, as is the case here.

However, it's important to note that the value of the constant acceleration (4 m/s²) applies only between 0 seconds and 2 seconds, after which the particle travels at constant velocity and the acceleration is zero.

An electrical insulator has" Electrons tightly bound to its atoms."The correct option is A.

An electrical insulator typically has electrons tightly bound to its atoms. This prevents the electrons from moving freely and thus inhibits the flow of electric current through the material. The lack of mobile electrons is a fundamental property that distinguishes insulators from conductors or semiconductors.

B. more protons than electrons: This option is not true because an electrical insulator can have an equal number of protons and electrons or even more electrons than protons. The balance between protons and electrons does not determine whether a material is an insulator or not.

C. Electrons that freely move: This option is not true for electrical insulators. Insulators are materials that do not conduct electricity easily, and one of the main reasons is that their electrons are tightly bound to their atoms. This lack of electron mobility prevents the easy flow of electric current.

D. Negatively charged ions: This option is not true for electrical insulators in general. Negatively charged ions refer to atoms or molecules that have gained extra electrons and carry a net negative charge. While some insulators may contain negatively charged ions, it is not a defining characteristic of electrical insulators as a whole. The primary characteristic of insulators is the inability to allow the free flow of electrons.

Therefore, The correct answer is option A.

Final answer:

The statement that is not true among the provided options is C) The gas pressure increases as the temperature decreases, because according to Gay-Lussac's law, the pressure of a gas should decrease as the temperature decreases when volume is held constant.

Explanation:

The question is asking which statement is not true regarding the behavior of gases, absolute zero, and the Kelvin scale.

Statement A) Absolute zero on the Kelvin scale is -273°C is true, because by definition absolute zero corresponds to -273.15°C, which is rounded to -273°C. This is the temperature where an ideal gas would theoretically reach zero volume.

Statement B) Liquefaction of the gas occurs at approximately -155°C is irrelevant to the correctness without additional gas-specific information, since the liquefaction temperature varies for different gases.

Statement C) The gas pressure increases as the temperature decreases is false. According to Gay-Lussac's law, for a given amount of gas at constant volume, the pressure of a gas is directly proportional to its temperature. Therefore, as temperature decreases, the pressure should also decrease assuming volume is held constant, which is not what the statement suggests.

Statement D) The gas follows a linear relationship between volume and temperature is true for an ideal gas. Figures presented in the information confirm that volume and temperature are directly and positively related for a gas following ideal behavior, with the relationship being linear up until liquefaction.

The not true statement among the options is C) The gas pressure increases as the temperature decreases.

The statement is false; horseshoe magnets produce magnetic fields, not electromagnetic energy. Electromagnetic energy is transmitted by waves with electric and magnetic fields, such as light and radio waves.

The statement (true or false) electromagnetic energy is the kind created by horseshoe magnets is false. Horseshoe magnets create magnetic fields due to their permanent magnetic properties, not electromagnetic energy. However, when electric current is used to create a magnet, as in an electromagnet, we can say that the magnetic field is created by electrical energy. On the other hand, electromagnetic energy refers to the energy transmitted by electromagnetic waves, which include light, radio waves, and x-rays. These waves have both electric and magnetic field components and carry energy through space, even in the absence of a physical medium.

To understand this better, consider that fields of force, like the ones that occur in the space around magnets, can carry energy across space. This demonstrates that the electromagnetic waves, which are basically vibrations in the electric and magnetic fields, are capable of transporting energy. So, while horseshoe magnets produce magnetic fields, they are not the source of electromagnetic energy in the way that electromagnetic waves are.

The magnitude of the charge on the plates of a parallel-plate capacitor necessary to establish an electric field of 2.0 x 10^6 V/m, with an area of 0.2 m^2 and plate separation of 0.1 mm, would be 4 x 10^5 C.

In relation to your question about a parallel-plate capacitor, the electric field (E) between the plates is proportional to the surface charge density, which is defined as the charge (Q) on each plate divided by the area (A) of the plate. By determining the charge on each plate, we use the equation E = Q/A. We can rearrange this equation to find the charge Q = E x A. Substituting the given values: Q = 2.0 x 106 V/m x 0.2 m2, gives us a result of Q = 4 x 105 C. Therefore, to obtain an electric field of 2.0 x 106 V/m between the plates of a parallel-plate capacitor, with a plate area of 0.2 m2 and a plate separation of 0.1 mm, the magnitude of the charge on each plate should be 4 x 105 C.

[tex]\[ E = \frac{V}{d} \][/tex]

where [tex]\( V \)[/tex] is the voltage across the plates and [tex]\( d \)[/tex] is the separation between the plates.

Rearranging to find [tex]\( V \)[/tex]:

[tex]\[ V = E \times d \][/tex]

Substituting the given values:

[tex]\[ V = 2.0 \times 10^6 \, \text{V/m} \times 0.0001 \, \text{m} = 200 \, \text{V} \][/tex]

2. Capacitance:

[tex]\[ C = \frac{\varepsilon_0 A}{d} \][/tex]

where [tex]\( \varepsilon_0 \) (the permittivity of free space) is \( 8.854 \times 10^{-12} \, \text{F/m} \)[/tex].

Substituting the given values:

[tex]\[ C = \frac{8.854 \times 10^{-12} \, \text{F/m} \times 0.2 \, \text{m}^2}{0.0001 \, \text{m}} \][/tex]

[tex]\[ C = \frac{1.7708 \times 10^{-12} \, \text{F}}{0.0001} \][/tex]

[tex]\[ C = 1.7708 \times 10^{-8} \, \text{F} = 17.7 \, \text{nF} \][/tex]

3. Charge:

The charge [tex]\( Q \)[/tex] on the capacitor is given by:

[tex]\[ Q = C \times V \][/tex]

Substituting the capacitance and voltage:

[tex]\[ Q = 17.7 \times 10^{-9} \, \text{F} \times 200 \, \text{V} \][/tex]

[tex]\[ Q = 3.54 \times 10^{-6} \, \text{C} = 3.54 \, \text{µC} \][/tex]

> What is the power rating?

The power rating can actually be calculated by the product of current and volts. Therefore:

Power = I V

Given that current I = 0.5 A and V = 120 volts, therefore:

Power = (0.5 A) (120 V)

Power = 60 Watts

> How much energy is consumed in 10 minutes

Energy is simply the product of power and time in seconds, therefore:

Energy = Power * time

Energy = 60 Watts * (600 seconds)
