The given statement, listening occurs when your ears pick up sound waves being transmitted by a speaker. is true, beacuse the sound waves vibrate the eardrum, which in turn sends signals to the brain that are interpreted as sound.

Listening occurs when sound waves are transmitted by a speaker and picked up by the ears. Sound waves are mechanical waves that propagate through a medium, such as air, and cause pressure changes that the ear can detect. When the sound waves reach the ear, they cause the eardrum to vibrate, which then sets off a chain of events that ultimately lead to the generation of electrical signals in the auditory nerve.

These electrical signals are then transmitted to the brain, where they are interpreted as sound. Without the sound waves being transmitted by a speaker or some other sound source, there would be nothing for the ear to detect, and hence, no listening would occur.

Answer:

The magnitude of the electrostatic force between the spheres is 2.25 x 10^-5 N, and its direction is towards the center of the two spheres (i.e., it is attractive).

Explanation:

To calculate the electrostatic force between two charged spheres, we need to use Coulomb's law:

F = k * (q1 * q2) / r^2

where F is the electrostatic force, k is Coulomb's constant (9 x 10^9 N m^2/C^2), q1 and q2 are the charges of the spheres, and r is the distance between their centers.

We don't have the charges of the spheres, so let's assume they have charges of q1 = 1 C and q2 = -1 C (positive and negative charges, respectively). The distance between their centers is r = 4 x 10^-1 m.

Plugging these values into Coulomb's law, we get:

F = (9 x 10^9 N m^2/C^2) * (1 C * -1 C) / (4 x 10^-1 m)^2

F = -2.25 x 10^-5 N

The negative sign indicates that the force is attractive, since the charges are of opposite signs.

Therefore, the magnitude of the electrostatic force between the spheres is 2.25 x 10^-5 N, and its direction is towards the center of the two spheres (i.e., it is attractive).

The electric fields are generally produced by changing the magnetic fields or electric charges. The electric field between the plates of area 5.68 × 10⁻³ m² and opposite charges of 4.38 × 10⁻¹¹ C is 8.714 × 10⁻²⁶ N/C.

The electric field can be defined as the electric force per unit charge. The electric field strength is usually measured in volt per meter. So its SI unit is V/m. The electric field is radially outwards from positive charge and radially in towards negative point charge.

The electric field between two parallel plates is:

E = Q / A × ε₀

Here  A = Area

Q = Charge

ε₀ = Permittivity of free space = 8.85 × 10⁻¹² C²/Nm²

Then,

E = 4.38 × 10⁻¹¹ C / 5.68 × 10⁻³ m² × 8.85 × 10⁻¹² C²/Nm²

= 8.714 × 10⁻²⁶ N/C

The parts of an experimental investigation that model the weathering of rock by water would involve observing changes in the rocks due to exposure to water, while the parts that model the erosion of rock by water would involve observing how water moves rocks from one location to another.

In order to gather data to support or disprove a causal relationship, experimental investigations entail a process in which a "fair test" is designed and variables are actively manipulated, controlled, and measured. A control group is used in experimental studies that receives no treatment.

Here, the weathering of rock by water can be modeled by exposing rocks to water and observing how they change over time. For example, if you were to place rocks in a container of water and leave them for a few days or weeks, you might observe changes in the rocks due to the effects of water. These changes could include physical weathering etc.

For erosion of rock by water, this can be modeled by observing how water moves rocks from one location to another. For example, if you were to create a miniature stream by running water over a surface with rocks, you could observe how the water moves the rocks downstream and changes their location.

According to Kepler's second law, in order for a planet in an elliptical orbit around the Sun to "sweep out equal areas in equal intervals of time," it must move faster when it is close to sun. Hence, option b is correct.

Kepler proposed three laws of planetary motion. The first law is says that every planets moves through an elliptical orbital around the sun. The second law states that "The path of the planets about the sun are elliptical in shape, with the center of the sun being located at one focus." This law is called law of equal areas.

According to Kepler's law of equal areas, an imaginary line between a planet and the sun would shift as the planet travelled along its elliptical course. The fictitious line would cut off a region as it went. Equal areas would be swept out in equal periods of time by the line.

The planet is not always at the same distance from the sun because of the elliptical nature of its orbit. The planet must move more quickly along its orbital route when it is closest to the sun in order for the area to remain constant during all time periods. Hence, option b is correct.
