Interaction between two charged particles is called

1 answer:

8 0

An interaction between two charged particles may give off energy. This interaction between them is called magnetism and that the force that is created is referred to as magnetic force or more specifically, electromagnetic force. The equation that best deals with this type of interaction is incorporated in Coulomb's law.

What is the purpose of using conductors in a circuit?

Aleonysh [2.5K]

Answer:

Conductors and insulators are both important in the field of electronics. Electrical conductors allow electric current to flow easily because of the make up of their atoms. In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied.

barxatty [35]

Answer:

A) is repelled by the sphere.

Explanation:

When a charged insulated rod is touched with an insulated conducting sphere , some charge on the rod gets transferred to the sphere . So they become similarly charged . We all know that there is repulsion when two similarly charged object are brought near to each other . Hence here too there will be repulsion between the rod and the sphere when the rod is brought near the sphere.

A wave travels along a stretched horizontal rope. The vertical distance from crest to trough for this wave is 13 cm and horizont

shepuryov [24]

Answer:

(A) The wavelength of this wave is $56\; \rm cm$ .

(B) The amplitude of this wave is $6.5\; \rm cm$ .

Explanation:

Refer to the diagram attached. A point on this wave is at a crest or a trough if its distance from the equilibrium position is at a maximum.

The amplitude of a wave is the maximum displacement of each point from the equilibrium position. That's the same as the vertical distance between the crest (or the trough) and the equilibrium position.

On the diagram, the distance between the two gray dashed lines is the vertical distance between a crest and a trough. According to the question, that distance is $\rm 13\; \rm cm$ for the wave in this rope.
On the other hand, the distance between either gray dashed line and the black dashed line is the distance between a crest (or a trough) and the equilibrium position. That's the amplitude of this wave.

Therefore, the amplitude of the wave is exactly $\displaystyle \frac{1}{2}$ the vertical distance between a crest and a trough. Hence, for the wave in this question,

$\begin{aligned}& \text{Amplitude}\\ &= \frac{1}{2} \times (\text{Vertical distance between crest and trough}) \\ &= \frac{1}{2} \times 13\;\rm cm = 6.5\; \rm cm\end{aligned}$ .

The wavelength of a transverse wave is the same as the minimum (horizontal) distance between two crests or two troughs. That's twice the horizontal distance between a crest and a trough in the same period.

$\begin{aligned}& \text{Wavelength}\\ &= 2 \times (\text{Horizontal distance between adjacent crest and trough}) \\ &= 2 \times 28\;\rm cm = 56\; \rm cm\end{aligned}$ .
