ANSWER:

कोई भौतिक गुण है जिसे मापा जा सकता है अर्थात कोई आंकिक मान दिया जा सकता है।

अन्तरराष्ट्रीय मापन शब्दावली की परिभाषा के अनुसार-

भौतिक राशि किसी वस्तु, पदार्थ या परिघटना का गुण है तथा इस गुण को संख्यात्मक मान एवं कोई मानक सन्दर्भ प्रदान किया जा सकता है।

अतः किसी भौतिक राशि Q को एक संख्यात्मक मान तथा एक इकाई (या मात्रक) के गुणनफल के रूप में अभिव्यक्त किया जाता है।

ANSWER:

EXPLANATION:

P=60 W

V=220 V

T=5 min=300 s

I=P/V

I=60/220

I=0.27 A

H=VIT

H=220*0.27*300

H=17820 J

so,

The unknown RESISTANCE X can be CALCULATED as:

2/3 = 4/X

X = (4 × 3)/2

X = 6.

Therefore The answer is 6 Ohms.

Answer:

Diffusion CURRENT is a current in a SEMICONDUCTOR caused by the diffusion of charge carriers (holes and/or electrons). ... The drift current, by CONTRAST, is due to the motion of charge carriers due to the FORCE EXERTED on them by an electric field.

SRRY i did not under your QUESTION

Answer:

When the object is placed very close to the lens, the IMAGE formed is virtual, ERECT and magnified. When used to see objects magnified, the convex lens is called a magnifying glass. A concave lens ALWAYS FORMS erect, virtual and smaller image than the object. White light is composed of seven colours.

Get some LENSES. Touch and feel them. Can you find some difference just by touching? Those lenses which feel thicker in the middle than at the edges are convex lenses. Those which feel thinner in the middle than at the edges are concave lenses. Notice that the lenses are transparent and light can pass through them.

Explanation:

DERIVE an EXPRESSION for the electric field intensity at a point on the axis of an electric dipole. The force experienced by a unit positive charge PLACED at a point is termed as the electric field intensity at that point. It is VECTOR quantity and it's direction is in the direction of force acting on +ve TEST charge.

Answer:

(1) Maximum speed occurs at x=3

(2) Maximum speed is V=4.183 m/s

(3) At x=6, V=0.

Therefore correct option is (B).

Explanation:

We will use the concept of kinetic energy. Since it is the only FORMULA which relates FORCE, distance, and area under the curve.

The kinetic energy at a GIVEN moment is equal to the work done from the beginning to that moment.

K.E= (1/2)x(M)x(V^2)

Area under the curve upto X=3 is, 17.5 Joule (J).

Mathematically,

Area= 2.5+2.5+5+5+2.5 = 17.5 J

Therefore, K.E at x=3 is 17.5 J

using formula,

17.5 J= (1/2)x(2)×(V^2)

V= 4.183 m/s

(For your practise, you can try to find velocity at different VALUES of X.)

ALSO at X=6,

K.E=0 J

Therefore, using formula

0 =(1/2)x(2)x(v^2)

V= 0 m/s

Also, as additional bonus let's find total kinetic energy.

Area under the curve= - 2.5 J

ANSWER:

=100radians/sec

Explanation:

angular velocity= 3000 (in NUMBER of RESOLUTIONS)

angular velocity=2πn

where n - number of revolutions/min

= 2π*3000

=6000π /min

=6000/60 for radians/sec

=100radians/sec

Answer:

DOPPLER Effect Derivation. Doppler effect is defined as the change in FREQUENCY or the wavelength of a WAVE with respect to an observer who is moving relative to the wave source. This PHENOMENON was DESCRIBED by the Austrian physicist Christian Doppler in the year 1842.

A state of EQUILIBRIUM of a body (as a pendulum standing directly upward from its point of support) such that when the body is SLIGHTLY displaced it departs further from the original position.

Definition of neutral equilibrium. A body is said to be in neutral equilibrium if on being slightly displaced it remains in its new position; e.g., a ball PLACED on a HORIZONTAL surface or a cone supported on its side on a horizontal surface.
