e is ur answer dear...It is present in all circuits, and in all components. When alternating CURRENT goes through an impedance, a voltage DROP is PRODUCED that is SOMEWHERE between 0o and 90o out of phase with the current. Impedance is mathematically symbolized by the letter “Z” and is measured in the unit ofohms (Ω), in complex form.thanks for the question

tral body can only be CHARGED POSITIVELY when one positively charged body which is identical to neutral body COMES in physical contact with neutral body , not he complete charge but some charge are TRANSFERRED to it

ld work out an ANALYTIC solution to this PROBLEM, but that is not necessary if you just WANT to be CONVINCED that the advice is good. All the forces on you are your own weight, straight down, and the force the ladder EXERTS on you. The vertical force which the ladder exerts is upward, so the net force in the vertical direction is smaller than if you were just falling.I hope this will help youIf not then comment me

ive Index (Index of Refraction) Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density. The refractive index variable is most commonly symbolized by the letter n or n' in descriptive text and mathematical equations.Figure 1 - Refraction of LightAs presented in the figure above, a wavefront incident upon a plane surface separating two media is refracted upon entering the second medium if the incident wave is oblique to the surface. The incident angle (θ(1)) is related to the refraction angle (θ(2)) by the simple relationship known as Snell's law:N1 × sin(θ1) = n2 × sin(θ2)Where n represents the refractive indices of material 1 and material 2 and θ are the angles of light traveling through these materials with respect to the normal. There are several important points that can be drawn from this equation. When n(1) is greater than n(2), the angle of refraction is always larger than the angle of incidence. Alternatively when n(2) is greater than n(1) the angle of refraction is always smaller than the angle of incidence. When the two refractive indices are equal (n(1) = n(2)), then the light is passed through without refraction.In optical microscopy, refractive index is an important variable in calculating numerical aperture, which is a measure of the light-gathering and resolving power of an objective. In most instances, the imaging medium for microscopy is air, but high-magnification objectives often employ oil or a similar liquid between the objective front lens and the specimen to improve resolution. The numerical aperture equation is given by:NA (numerical aperture) = n × sin(θ)where n is the refractive index of the imaging medium and θ is the angular aperture of the objective. It is obvious from the equation that increasing the refractive index by replacing the imaging medium from air (refractive index = 1.000) with a low-dispersion oil (refractive index = 1.515) dramatically increases the numerical aperture.Interactive Tutorial - Refraction of LightExamine how refractive index varies with the dispersion of properties of different materials.Snell's law was originally defined by the relationship between the incident angles and the ratio of the velocities of light in the two media. The refractive index or index of refraction is the ratio between the velocity of light (c) in free space (for all practical PURPOSES, either air or a vacuum) and its velocity η in a PARTICULAR medium:n = c/ηAs the refractive index of a material increases, the greater the extent to which a light beam is deflected (or refracted) upon entering or leaving the material. The refractive index of a medium is dependent (to some extent) upon the frequency of light passing through, with the highest frequencies having the highest values of n. For example, in ordinary glass the refractive index for violet light is about one percent greater than that for red light. A consequence of this phenomenon is that each wavelength experiences a slightly different degree of refraction when a heterogeneous light beam containing more than one frequency enters or leaves the medium. This effect is termed dispersion and is responsible for chromatic aberration in microscope objectives.I think it is helpful to you so,plz MARK ME AS BRAINLIEST

The ANGLE between two surfaces is KNOWN as refracting angle or angle of prism. In a prism, a ray of light suffers two REFRACTION and the result is deviation. In other words, we SAY that after passing through prism the ray of light deviates through a CERTAIN angle from its original pathmark me as brainiest

urrent is steady induced current is not produced in the loop as there is no change in magnetic flux.(2)If it is INCREASING -By right HAND rule the magnetic field is perpendicular to the plane of paper outwards.By lenz's LAW induced current should oppose the increase in flux . So induced current flows in clockwise direction.Please MARK the answer brainliest.

try to post complete question :The complete question should be some what like this:A Coil of insulated COPPER wire is connected to a galvanometer.  What will happen if a bar magnet is : a) PUSHED into the  coil.  b) Withdrawn from the coil.  c) Held stationary near the coil.  Give reasons for your observation.Answer :a)When a bar magnet is pushed inside the coil, an induced current is setup in the coil as the magnetic flux linked with coil changes continuously and galvanometer deflects TOWARDS right side.b) When bar magnet is moving away from coil, as there is changing in magnetic flux linked to coil, induced current is setup and galvanometer deflects in OPPOSITE direction.c) When magnet is held stationary, as there is no change in magnetic flux , the current is not induced and galvanometer will not deflect.
