By applying `ASA` congruence rule, it is to be established that `/_\ABC cong /_\QRP` and it is given that `BC = RP`. What additional information is needed to establish the congruence?

Text Solution

Verified by Experts

For `ASA` congruence rule, we need the two angles between which the two sides `BC` and `RP` are included. So, the additional information is as follows:
`/_B = /_R`
and `/_C = /_P`

Consider two coherent sources S_(1) and S_(2) producing monochromatic waves to produce interference patten. Let the displacement of the wave produced by S_(1) be given by and the displacement by S_(2)" be" " " Y_(1) = acos omegat Y_(2) = a cos ( omegat -phi) Find out expression for the amplitude of the resultant displacement at a point and show that the intensity at that point will be I = 4a^(2) cos^(2) phi//2 Hence establish the conditions for constructive and destructive interference. (b) What is the effect on the interference friinges in Young's double slit experiment when (i) the width of the source slit is increased, (ii) the monochromatic source is replaced by a source is replaced by a source of white light ? OR (a) A ray, 'PQ' of light on the face AB of glass prism ABC (as shown in the figure) and emerges out of the face AC. Trace the path of the ray. Show that anglei + anglee= angleA+ angledelta Where delta and e denote the angle of deviation and angle of emergence respectively. Plot a graph showing the variation of the angle of deviation as a function of angle of incidence. state the condition under which angledelta is minimum. (b) Find out the relation between the refractive index (mu) of the glass prism and angleA for the case when the angle of prism (A) is equal to the angle of minimum deviation (delta_(m)) . Hence obtain the value of the refractive index for angle Ae=60^(@) .

Beyond the hype and glamor synonymous with the fashion industry are challenges that business owners face when trying to establish themselves in the sector. Competition in the fashion industry makes it difficult for small businesses to get the attention of the market since the media mainly covers established fashion houses. However, passionate entrepreneurs who choose to venture into fashion can succeed by dedicating time, resources and persistence. Investing in the fashion industry requires a lot of capital for startup and the initial running of the business. Obtaining additional financing from investors and banks may prove especially difficult when you do not have sufficient records to demonstrate your ability to repay. Operating within a limited budget would force you to cut down your expenditure on crucial items such as marketing and publicity for your brand. Hiring the right personnel to work for your fashion business plays an important role in its success. However, the right personnel comes at a price that may be too high for your business. Your budget can force you to compromise on the qualification and experience of the staff you need. In addition, talented individuals in the fashion industry may only commit to an established fashion business and only agree to work for your firm on a part-time or freelance basis. Such people may also need more money to convince them to come on board. The competition in the fashion industry is a disadvantage to small and upcoming businesses. For example, startup ventures may not have enough money to poach personnel but may lose personnel through that approach. Such businesses, despite their limited budget, need to invest more time and resources in marketing and creating visibility for their brand. Additionally, small businesses may have a higher running cost given that they make smaller orders compared to established brands. For example, established brands will make large orders in China while unestablished players have to rely on local manufacturers whose price is much higher. New businesses also face a higher risk of failing to take off. The fashion industry demands long hours to network, market, design and exhibit your work. In the initial stages, you have to work longer hours as you often take on multiple responsibilities. The long hours you spend may also limit your creative input especially if you design. You also have to sacrifice time away from your family, friends and social life. What is the main idea of the passage?
