the RESISTANCE of a conductor is CONSTANT provided its physical conditions such as temperature ,remain constant.The POTENTIAL difference ACROSS an ideal conductor is proportional to the current through it

If we assume EARTH is EXAMPLE of solid sphere.
we know, moment of INERTIA of solid sphere about its AXIS of rotation , I = 2/5 MR²
where M is mass of solid sphere and R is the radius of it.

so, Moment of inertia of earth about its axis of rotation = moment of inertia of solid sphere about its axis of rotation
= 2/5 MR²

if M = 5.97 × 10²⁴ KG,
R = 6.38×10^6 m,

so, I = 2/5 × (5.97 × 10²⁴) × (6.38 × 10^6)²
= 97.202 × 10^36
= 9.7202 × 10^37 kgm²

To determine the FOCAL length of a concave mirror, by obtaining image of a distant object.

TheoryA concave mirror, like a plane mirror, obeys the laws of reflection of light.RAYS of light from object - The rays of light coming from a distant object e.g. sun or a distant building can be considered to be PARALLEL to each other. When these parallel rays of light fall on a concave mirror along its axis, reflect and MEET at a point in front of the mirror, which is called as Principal focus of the mirror.A real, inverted and very small image size is formed at the focus of the mirror.Focal Length - The distance between the pole P of the concave mirror and the focus F is the focal length of the concave mirror. THUS, the focal length of a concave mirror can be estimated by obtaining a 'Real image' of a distant object at its focus

▶Let ‘r’ be the radius of the disc.

♦ Given,

➧ MOMENT of inertia of the disc about PQ, IPQ
➾ 2 UNITS

➧ Moment of inertia of the disc about AB, IAB
➾ ½ Mr²


➧ We need the MI of the disc about RS or IRS.

♦ Now

➧ From theorem of perpendicular axes,

IAB = 2IPQ

➾ ½ Mr² = 2

➾ Mr² = 4

➧ Now, by theorem of PARALLEL axes

Carbon BRUSHES are used in both DC and AC generators. Nowadays , no carbon brushesare used in AC generators , INSTEAD of brushes another small generator mounted on the same SHAFT of rotating ARMATURE called exciter is used to provide excitation to the field winding . THUS AC is generated by AC machine.

12.5 ANSWER of your QUESTIONS

When SOMEONE is SWIMMING in the pond or RIVER and the engine is pulling the TRAIN

Due to refraction of light.

When light RAY coming from denser ta rairer media the light BENTS away from normal.and image SEEMS closer to the SURFACE.

LCR-liquidity COVERAGE RATIO

Since every matter is MADE up of small particles and sound propagate by vibration of particles .

hence every matter which has particles can allow sound to PASS through them.

sound pass faster in SOLID then SLOWER in liquids and then slowest in gas. ..

The energy of a BODY DUE to it's MOTION is KNOWN as KINETIC energy.

First law:In an INERTIAL frame of reference, an object either REMAINS at rest or continues to move at a constant velocity, unless acted UPON by a force.[2][3]Second law:In an inertial frame of reference, the vector sum of the forces F on an object is equal to the mass m of that object multiplied by the acceleration a of the object: F = ma. (It is assumed here that the mass m is constant – see below.)Third law:When one body EXERTS a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.

It is at REST so it does not POSSESS any ENERGY
but if PUSHED it will possess POTENTIAL energy

PLEASE MARK AS BRAINLIEST ^_^

For example, when you pedal a bicycle and CONTINUE it to pedal the same way for a certain time, you GET a CONSTANT velocity.

In absence of friction it is not USED and consumed energy.

➧ If you will MOVE towards the MIRROR with a velocity of 10 m/s , the mirror image will move towards to you with velocity of 10 m/s only.

➧ THUS, your SPEED towards mirror + mirror image speed towards you is 20 m/s:-

➧ So, 10 + 10
➾ 20 m/s ...✔

fossil fuel RESULT from a transformation of plant and ANIMAL material over millionof YEARS .The solar energy ORIGINALLY STORED in the plant or animal is eventually converted to energy stored in carbon and hydrogen bonds pf the fossil fuel

when the light falls on the face of GLASS PRISM

the white light is SEPARATED into its component colors - red, orange, yellow, green, BLUE and violet. The separation of visible light into its different colors is KNOWN as dispersion.

The FIRST equation represents kinetic ENERGY of the MEAN flow (MKE) and second equation represents kineticenergey of turbulent PART of the flow(TKE). The second equation is also-called turbulent kinetic energy.Turbulent kinetic energy is one of the most IMPORTANT variables in micrometeorology.

Luminiferous aether or ether, was the POSTULATED medium for the PROPAGATION of light. It was invoked to EXPLAIN the ability of the apparently wave-based light to PROPAGATE through empty space, something that waves should not be able to do.

The wavelengths of red (620–750 nm) and blue (450–495 nm) light are less than 67% apart, so that a screen with TWO slits (with the distance between the slits comparable to those wavelengths) can serve for both of the two beams, even simultaneously. If performed simultaneously, each of the two beams will form its own pattern of alternating bright/dark fringes, one superposed over the other. Since the distance between the fringes is proportional to the wavelength, the distance between the bright-red fringes will be 25–67% bigger (depending on which particular wavelengths are present in your “red” and “blue” beams) than the distance between the bright-blue fringes.

The color of the overlap between them should be bright-magenta, owing to so-called “additive color mixing.” Wikipedia has a figure [File:Double SLIT interference.png - Wikipedia] showing the result with “WHITE light,” i.e., all colors of the rainbow, not just red and blue.

A wave motion is in a form of DISTURBANCE which travels thorough a medium due to the vibrations of the PARTICLES of the medium. It is the disturbance which travels in the forward DIRECTION and not the particles. The particles SIMPLY vibrate about their mean position

The valence of a tensor is the NUMBER of variant and covariantterms, and in Einstein notation,covariant components have lower indices, while contravariantcomponents have upper indices. ... In tensor analysis, a covariant vector VARIES more or LESS reciprocally to a corresponding contravariant vector.
