Correct option is (b) Traders

(i) A cavity radiator is a block of material with internal cavity. The inner and outer surfaces of the block are connected by a small hole. Most of the radiant energy entering the block through the hole cannot escape from the hole. The block, therefore, acts almost like a blackbody.

(ii) When the cavity radiator is heated to high temperature, radiation coming out from the hole resembles blackbody radiation. It is called cavity radiation. It depends only on the temperature of the radiator and not on the shape and size of the cavity as well as the material of the walls of the cavity.

No. 

Since a + r + t = l,a = 0 and t = 0 for r = 1. Therefore, by Kirchhoff’s law, e = a = 0 which is impossible as every body at temperature above 0 K does emit radiant energy, and T = 0 K is impossible.

A blackbody being a full radiator, when heated to high enough temperature it would emit thermal radiation at all the wavelengths and thus appear white. A perfect reflector (r = 1), on the other hand, is a poor emitter and thus would not necessarily appear white when heated.

Correct option is (c) Jal Cooper

Correct option is (d) All of these

Net value added at market price

= Sales + (Closing stock- Opening stock) – Intermediate consumption – Depreciation

= 90+ (25-15) -40 – 20

= ₹ 40 crores

The three methods of national income are.

• Value Added Method
• Income Method
• Expenditure Method

Gross value added at factor cost

= Sales + (Closing stock – Opening stock) – Purchase of intermediate products + subsidy

= 500+ (20-30) – 300 +40

= ₹230 thousand

Intermediate consumption

= Value of output – Net value added at factor cost – Depreciation – (GST-Subsidy)

= 200 – 80 – 20 – (15 – 5)

= ₹90 lakhs

Gross National Disposable Income

= (i) + (vi) + (ii) - (vii) - (v) + (iii)

=3,000 + 200 + 300 - 100 - 150 + 250 

=Rs.3,500 crore

If the demand curve is a rectangular hyperbola, elasticity is One 

Consider the side of a square as a

It is given that the rate of change of side is

da/dt = 0.2 cm/s

We know that the perimeter of a square = 4a

So the rate of change of perimeter is

4 da/dt = 4 × 0.2

We get

dP/dt = 0.8 cm/s

We know that a soap bubble will be in sphere shape

Consider the radius of soap bubble as r

dr/dt = 0.2 cm/s

The surface area of soap bubble = 4 πr²

So the rate of change of surface area = 8πr dr/dt

By substituting the values

= 8 × 3.14 × 7 × 0.2

We get

dS/dt = 35.2 cm²/s

We know that a soap bubble will be in sphere shape

Consider the radius of soap bubble as r

dr/dt = 0.5 cm/s

The volume of soap bubble = 4/3 πr³

Here the rate of change of volume = 4 πr² dr/dt

By substituting the values

= 4 × 3.14 × 1² × 0.5

We get

dV/dt = 6.28 cm³/s
