The resistance across the galvanometer is 50Ω. 
Which is connected to a battery V=3V with a series resistance R = 2950Ω . On the basis of the information provided in the question the circuit will look like above figure. The current across the galvanometer will be: 

Current for 30 divisions = 10^-3A 

Current for 20 divisions =

In order to reduce all deflection to 20 divisions , the resistance R is added which is solved as: 

R = 4450 Ω

Self-inductance of coil 1 = 2 mH 
Self-inductance of coil 2 = 8 mH 
When the total flux associated with one coil links with the other i.e., a case of maximum flux linkage, then 

The resistance between the two diametrically opposite points A and B can be shown as : 

The circumference of the circle is given by : 

Since the resistance distribution is divided into two section so, the resistance of each section will be represented as :

The equivalent resistance will be given as : 

According to Ohm’s law: 

V = IR where I is the current and R is the resistance present in the conductor 
Suppose V is the terminal potential difference of a cell 
And the cell has the emf = ε and the internal resistance = r then we can write: 
V + Ir =  ε
If I = 0 
Then we can write, V = ε i.e. terminal potential difference is equal to the emf of the cell. 
The slope will be given as:

By, following the Ohm’s law.

Given that the galvanometer has a coil of resistance, G= 60Ω 
And it shows a full scale deflection when current I=1.0A is passed through it. 
And we know that a galvanometer can be converted into an ammeter by connecting a resistor in parallel to the galvanometer coil. 
Here , G = 60 Ω , I_g= 1A, I = 5A and we need to find the value of R 
I_gG = (I – I_g)R 
Or R = I_gG/(I – I_g) 
By putting the respective values R becomes 
R = 15Ω

Maxwell found wave theory of light and found out that light is transmitted in the form of electromagnetic waves. Electromagnetic waves transmit with same velocity equals to that of the light. Electromagnetic waves do not require any medium for propagation.

In this diagram, the point of maximum amplitude of wave is crest while of lowest amplitude is trough.

Emulsion is widely used in food industry (mayonnaise, milk). They have medical and metallurgical applications. Digestion of fats in intestine occur with help of emulsion.

Adsorption process is exothermic hence adsorption decrease with increase in temperature.

The general formulae of Langmuir adsorption isotherm is 
Θ=K[X]/1+K[X] 
For very low concentration of the gas, 1>>>>K[X] and hence, 1+K[X]=1
∴θ=K[X]/1=K[X]

All the tissue outside the vascular cambium constitutes of Bark.  Various kinds of cell layers that constitute the bark are Periderm that includes Phellogen, Phellem and Phelloderm, primary cortex, Pericycle, Primary and secondary Phloem. These all tissue are present outside the vascular cambium. The bark is formed early in the season is called early or soft bark and thus formed the ends of the season is called late or hard bark.

• Thus, Bark excludes the term Secondary cortex

Atactostele is the type where vascular bundles are scattered. Monocot stems show this feature. Hence the correct answer would be maize.

Root endodermis has casparian strips in the form of suberin depositions of the radial and inner walls of the cells. It is a feature of the root tissue system.

Most of the angiosperm families have anatropous ovules. In an anatropous condition, ovules are inverted during the development phase so that the micropyle lies very close to the hilum. 

Autogamy is refers to self-pollination where pollination occurs within the same flower. Self-pollination takes place in cleistogamous flowers where anther and stigma lie very close to each other. In homogamy, the pollen is shed at the same time when the stigma becomes receptive resulting in intra floral self-pollination. In bud-pollination, stigma and pollens ripen at the same time inside the bud resulting in self-pollination.

In dicliny condition, flowers are unisexual bearing either stamens or pistils. Fertilisation occurs in these flowers by cross pollination.
