Answer:

Electrical resistivity: It is a property of MATERIAL. It is the strength of material to oppose the FLOWING current in the conductor made by the material. It does not depends on shape and size of conductor. It depends on nature and TEMPERATURE of the conductor.

Answer:

When the road is banked, the HORIZONTAL component of the NORMAL REACTION provides the necessary centripetal force required for circular motion of vehicle. .

. THUS, to provide the necessary centripetal force at the CURVED road, banking of road is necessary.

hope it helps ✔✔☺❤☺❤❤

ANSWER:

Banking of road is the process of raising OUTER edges of a road over its inner EDGE through certain angle. ... When road is banked, the horizontal component of normal REACTION provides necessary centripetal force required for circular MOTION. So, roads are banked to provide necessary centripetal force.

Answer:

A.C. generators or alternators (as they are usually called) OPERATE on the same fundamental principles of electromagnetic induction as D.C. generators.

Alternating VOLTAGE MAY be generated by rotating a COIL in the magnetic FIELD or by rotating a magnetic field within a stationary coil. The value of the voltage generated depends on-

the number of turns in the coil.

strength of the field.

the speed at which the coil or magnetic field rotates.

Answer:

The mirror formula

1f=1v+1u

Where

f

is the focal length of the mirror,

u

is the DISTANCE of the object from the mirror and

V

is the distance the image is formed from the mirror.

m=−vu

The size of an object’s image is larger (or smaller) than the object itself by its magnification,

M

. The level of magnification is proportional to the ratio of

v

and

u

. An image that is double the size of the object WOULD have magnification

M=2

.

R=2f

The radius of curvature of a mirror is twice its focal length.

Example 1

In the SITUATION illustrated below, the object is SET up .5 m away from a converging mirror. If the focal length of the lens is .2 m, determine a) the location of the real image, and b) the magnification of the image.

Answer:

Here we can use conservation of energy since no external agencies are acting.

K.E = Elastic potential energy

1/2mv^2 = 1/2kx^2

1kg × 4 = 0.25 × X^2

16 = x^2

Thus x = 4m compression

Answer:an apple thrown in space

A photon has ZERO acceleration

EXPLANATION: acceleration is zero when VELOCITY is CONSTANT

Answer:

The formula you will use for isothermic expansion is:

Work(W) = 2.303 RT LOG(V2/V1)

Let R = 8.3 J / mole-K (universal gas CONSTANT and V2/v1 = 2/1 = 2.

Converting temperature to KELVINS:

T = 127°C = 400K

Work(W) = (2.3)(8.3)(400)log(2)

W = 2.3 X 10^3 J

To find the heat absorbed:

2.3 x 10^3 J/4.2 = 548 cal.

Answer:

In physics, RADIATION is the emission or transmission of ENERGY in the form of WAVES or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ULTRAVIOLET, x-rays, and gamma radiation (γ)

I think it will help you

Answer:

Thermionic emission is the liberation of electrons from an ELECTRODE by virtue of its temperature. This occurs because the thermal energy given to the carrier OVERCOMES the WORK function of the material. The charge carriers can be electrons or ions, and in older literature are sometimes REFERRED to as thermions.

Answer:

Critical Phenomena and Van der Walls Equation:

For one mole of a GAS the Van der Waals equation,

(P + a/V2)(V - b) = RT

V3 - (b + RT/P)V2 + (a/P)V - ab/P = 0

This equation has three roots in V for given values of a, b, P and T. It found that EITHER all the three roots are REAL or one is real and the other two are imaginary.

Expression of Critical Constants in Terms of Van der Waals Constants:

Again with increase of temperature the minimum and MAXIMUM points come close to each other and at the critical point (C) both maximum and minimum coalesce. The slope and curvature both becomes zero at this point.

THUS the mathematical condition of critical point is,

(dP/dV)T = 0 and (d2P/dV2)T = 0

Van der Waals equation for 1 mole gas is,

(P + a/V2)(V - b) = RT

or, P = RT/(V - b) - a/V2

Differentiating Van der Waals equationwith respect to V at constant T,

We get Slope,

(dP/dV)T = - {RT/(V - b)2} + 2a/V3

And Curvature,

(d2P/dV2)T = {2RT/(V - b)3} - 6a/V4

Hence at the critical point,

- {RTC/(VC - b)2} + 2a/VC3 = 0

or, RTC/(VC - b)2 = 2a/VC3

and {2RTC/(VC - b)3} - 6a/VC4 = 0

or, 2RTC/(VC -b)3 = 6a/VC4

Thus, (VC - b)/2 = VC/3

∴ VC = 3b

Putting the value of VC = 3b in

RTC/(VC - b)2 = 2a/VC3.

We have, RTC/4b2 = 2a/27b3

∴ TC = 8a/27Rb

Again the Van der Walls equation at the critical state,

PC = RTC/(VC - b) - a/VC2

Putting the value of VC and TC,

∴ PC = a/27b2

Answer:

X coordinate is negative SIDE i.e on the same side of the source and left side tonthe lens

Explanation:

Becuase the image formed by the lens is at BEHIND it and then it FALLS on the diverging mirror and THEREBY REFLECTED and comes back to same side i.e positive x coordinate
