a. Violet, Indigo, Blue, Green, Yellow, Orange, Red 

b. Dispersion. The phenomenon of splitting, of a composite light into its constituent colours is known as dispersion of light.

c. A – Violet B – Red 

d. Violet 

e. Red

f. Different colours undergo different deviation due to difference in wavelength

Colour in it undergoes maximum scattering: Violet Colour in it undergoes minimum scattering: Red

Morning and evening.

Red colour is seen at the end.

Red, it has highest wavelength and least scattering.

The primary reason why the colour red is used for danger signals is that red light is scattered the least by air molecules. So red light is able to travel the longest distance through fog, rain, and the like.

a. Green colour 

b. When yellow light falls on a green paper it absorbs yellow and reflects green. So . the green colour is seen on the screen.

During sunset, the sunlight travels maximum distance through the atmosphere to reach in our eyes. So red also undergoes scattering. So the horizon appears red.

Yes, These colours are the same as the component colours obtained from the sunlight?

Correct answer is (a) μ > 1

A spec sheet is a technical document that contains the construction details of embroidery, a technical diagram/sketch and measurements of embroidery

it might will be unfair to both the client and the worker or damages the reputation of the organisation or the business handling the project.

Main elements of communication are: 

1. Sender: Sender means person who conveys his thoughts or ideas to the receiver. 
2. Message: It is the content of ideas, suggestions, order etc. intended to be communicated. 
3. Encoding: It is the message into communication symbols such as words, pictures, gestures etc. 
4. Media: It is the path through which encoded message is transmitted to receiver. 
5. Decoding: It means translating the message from its sign format into meaning. 
6. Receiver: The person who receives communication of the sender. 
7. Feedback: It includes all those actions of receiver indicating that he has received and understood the message of sender. 
8. Noise: Noise means some obstruction or hindrance to communication.

a.drop of dish soap and water. 

b. spray the area with acetone or bleaching agent in case of white fabrics depending upon the type of stains

Correct answer is (c) 1500 J

Matty, gingham, casement, khadi, jute

Adult size- 11 to 14 inches 

Kids- 5.5 to 9 inches 

Also to note size can change depending on what you are making.

Things to keep in mind while writing a bio data: 

1. Check for typos, grammatical errors. 

2. If your career demands a two page resume, then go ahead and do it. 

3. Don’t lie over dates or titles on your resume to hide the fact that you have been unemployed. 

4. If you are seeking a job in a field in which you have no prior experience, don’t use the chronological format for your resume.

Signature

Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 10⁷ ergs, or approximately 0.7377 foot-pounds.

Horsepower refers to the power an engine produces. It's calculated through the power needed to move 550 pounds one foot in one second or by the power needs to move 33,000 pounds one foot in one minute. The power is gauged by the rate it takes to do the work.

a. Osmosis: The spontaneous and unidirectional flow of solvent molecules through a semipermeable membrane, into the solution or flow of solvent from a solution of lower concentration to the solution of higher concentration through a semipermeable membrane is called osmosis.

b. Freezing point: The freezing point of a substance may be defined as the temperature at which the vapour pressure of solid is equal to the vapour pressure of liquid.

a. Dilute H₂SO₄ reacts with Fe which is below hydrogen in the electrochemical series, with the evolution of H₂.

Fe (Iron) + H₂SO₄ (Sulphuric acid) → FeSO₄ (Ferrous sulphate) + H₂ (Hydrogen)

b. When H₂SO₄ is added to calcium fluoride, hydrogen fluoride is obtained. 

CaF₂ (Calcium fluoride) + H₂SO₄ (Sulphuric acid) → CaSO₄ (Calcium sulphate) + 2HF (Hydrogen flurode)

Isolation method: 

a. In the isolation method, the concentrations of all the reactants except one are made to remain constant throughout the course of the reaction by taking them in large excess. The dependence of rate on the concentration of the isolated species is experimentally determined. 

b. The experiment is repeated by isolating one of the reactants each time and determining the rate law with respect to the isolated species. 

c. Consider the reaction

aA + bB → cC + dD

The rate law has the form,

Rate = k[A]^x[B]^y

d. In one of the experiment, A is isolated by making the initial concentration of B (i.e., [B]₀) to remain constant throughout the course of the reaction (by taking it in large excess). 

Hence, the rate law is written as

rate = k[A]^x\([B]^y_0\) = k'[A]^x  (where, k' = k\([B]^y_0\))

The dependence of rate on [A] that is ‘x’ is found out.

e. In another experiment, B is isolated by keeping initial concentration of A (i.e., [A]₀) constant throughout the course of the reaction (i.e., by taking it in large excess). 

The rate law then becomes, Rate =  K\([A]^x_0\) [B]^y = k'' [B]^y (where, k'' = k\([A]^x_0\))

The dependence of rate on B that is y is found out.

f. Thus, by knowing the values of x and y, the order of the reaction (x + y) and the rate law can be determined.

Nernst equation can be given as,

E = E⁰ - \(\frac{2.303\,RT}{nF}log_{10}\,\frac{[Products]}{[Reactants]}\)

where,

E⁰ = Standard potential of electrode or cell, 

n = Number of moles of electrons used in reaction, 

F = Faraday = 96500 C/mol e^- , [Products] = Concentration of products, 

[Reactants] = Concentration of reactants, T = temperature in K and 

R = gas constant = 8.314 J K^-1 mol^-1

a. Galvanization:

1. The rusting of iron can be prevented by coating the metal surface with another metal such as zinc,thatis oxidized in preference to iron. This process is called galvanization.

2. If the zinc layer is scratched, even then it protects iron from corrosion as long as Fe and Zn are in contact. If Fe is oxidized to Fe²⁺, then Zn immediately reduces Fe²⁺ back to Fe.

b. Passivation: The surface of metal is treated with strong oxidizing acid such as concentrated nitric acid and a thin preventive layer of oxide is formed on the surface of metal. Thus, the surface is made inactive. This is process is called as passivation.

Correct answer is:- (D) The genetic code is degenerate

101.101 = 1 x 2² + 0 x 2¹ + 1 x2⁰ + 1 x 2^-1 + 0 x 2^-2 + 1 x 2^-3

= 4 + 0 + 1 + 1/2 + 0 + 1/8

= 5 + 0.5 + 0.125

(101.101)₂ = (5.625)₁₀

101.101 = 1 × 2² + 0 × 2¹ + 1 × 2⁰ + 1 × 2^-1 + 0 × 2^-2 + 1 × 2^-3 = 4 + 0 + 1 + 1/2 + 0 + 1/8 = 5 + 0.5 + 0.125 

(101.101)₂ = (5.625)₁₀

Correct option is B) off
