বৈশ্বিক উষ্ণায়নঃ সমস্যা ও প্রতিবিধান
বৈশ্বিক উষ্ণায়নঃ
বৈশ্বিক উষ্ণায়ন/জলবায়ু পরিবর্তনের চিহ্ন / প্রভাবঃ
বৈশ্বিক উষ্ণতার সমস্যাসমূহঃ
তাপমাত্রা বৃদ্ধিঃ
সমুদ্র পৃষ্ঠের উচ্চতা বৃদ্ধিঃ অনেক গবেষনায় এটা প্রমাণিত যে,
বৃষ্টিপাতে বৈচিত্র্যতায়ঃ
প্রাকৃতিক দুর্যোগঃ
কৃষি উৎপাদন ও খাদ্য নিরাপত্তাঃ
পরিবেশ ও জীববৈচিত্র
মানব স্বাস্থ্য
বৈশ্বিক উচ্চতার প্রতিবিধানঃ
বৈশ্বিক উষ্ণায়ন একটি সার্বজনীন সমস্যা। এই সমস্যার আশু সমাধান না হলে বিশ্ববাসীকেই এর খেসারত দিতে হবে। কাজেই এর দ্রুত ও দক্ষ একটি সমাধান প্রয়োজন যা সম্মিলিতভাবে নিতে হবে। এই উষ্ণায়ন রোধে একটি দেশ নিচের পদক্ষেপগুলো করতে পারেঃ
আমার একটি স্বপ্ন এই যে একদিন সকল উপত্যকা মহিমান্বিত হবে, প্রতিটি পাহাড় ও পর্বত নিচু হবে, প্রতিটি অন বিস্তীর্ণভূমি সমতলে পরিণত হবে, আঁকাবাকা স্থানগুলো সবল হবে আর মহান সৃষ্টিকর্তার মহিমা প্রকাশিত হবে এবং সবাই তা দেখবে। এটাই আমাদের আশা। এটাই সেই বিশ্বাস যার দ্বারা আমি দক্ষিণ
পশ্চিমাঞ্চলে গমণ করি। এই বিশ্বাস দ্বারাই আমরা পাহাড়সম নৈরাশ্যের পাথর ভেঙে আশায় পরিণত করতে পারি।
অধিকাংশ লোকেরই সময়জ্ঞান নেই
এটা তোমার পছন্দের জিনিস নয়।
বৃহত্তর সফলতাই উৎকৃষ্ট প্রতিশোধ।
লোকজন শত শত বছর ধরে অনেক কুসংস্কার ধারণ করে আসছে।
সর্বদাই প্রস্তুত রয়েছে এমন মানুষের উপরই ভাগ্য কেবল সুপ্রসন্ন হয়।

The value and significance of a life depends upon the goal towards which it moves.
Only rational beings like us are culpable of a critical choice.
Our supreme goal or highest good (summum bonum) of our life is rationality.
Our total good consists of rational and non-rational factors.
The happiness is the non-rational factor because there is no logic either for or against it. In fact, we cannot logically argue why we shall be happy or why we shall be not.
I don't blame on people. Listening true abruptly may create anger. When you pull up an absent minded person who is going to fail into hole, may react in an awkward way. Anger passes away as soon as he/she confronts the hole. It is high time we need not make them aware anymore they have already confronted the holes.

The next wave of Social Media
Points on how social media will transform in the future is furnished below:
1. A Focus on Relationships: Social media will probably begin to draw the focus back into relationships by emphasizing personal posts, photographs and small, intimate connections over outside content like memes and articles.
2. Diversity of personal posts: Until now, posts have been limited to outside material, pictures, videos and text. As digital technology progresses, people will be hungry for new and interesting ways to share experience. The importance audio will play in social media's future.
3. Users will pay for peace: Premium service will make a splash. This one sounds counter intuitive after all, who would pay f a social media experience when they've all been free up to this point. Two things will happen change that previnus wisdom. First, with a more personal, story-driven experience, customers will want high-quality images, videos and audio files stored for posterity. Second, having a place escape constant advertisements will become very important, something a premium social media experience will offer.
4. Increased focus on privacy: Privacy concerns have plagued social media since its inception, and are only getting m pronounced Expect future social media companies to offer more advanced network and profile privacy than ever before.
5. Video, video, and more video: In late 2016, we saw a major development in social media video when Instagram release Instagram Stories and Instagram Live Instagram's parent company Facebook also released Facebook Live and Messenger Day. The focus on the live format follows in the footsteps of Snapchat and Twitter's Periscope.
6.Less Gamification: One of social media's key components is that it's highly addictive, even going so far as to be described as more addictive than cigarettes. New platforms will try to gear more toward long-term customer wellness as a feature staving off more addictive qualities. They will focus more on the communal quality of social media rather than offer quick hits of serotonin from gratifying and frustrating outside content.
7. Legacy building; As has been said many times, the internet is written in ink. It cannot be erased, and in the future, people won't want it to be. Users will want their social media to existing as an ongoing time capsule, a living record of their lives. Smart platform builders will realize posting shouldn't be a burst about a single moment in time, to be consumed in a few seconds and forgotten about immediately, but as a multi-faceted, interactive diary involving many writers, all telling pieces of their own and others stories.
8. Open to experimentation: The main social media giants are slow, lumbering machines, resistant to change, and unbearably clumsy when they do change. Future models will have seen platforms of the past try different things to different levels of success and will be open to explore. They will try our wildly different ways of managing contacts, befriending people, organizing interface layouts, etc. Facebook has had basically the same layout since its beginning- don't expect that to be the case with new platforms.
9. Mobile-native: A mammoth advantage new platforms will have is that they about after the smartphone became The future of the internet is mobile, so it stands to reason that mobile native platforms will be built to last.

The profit of a company is given in taka by p= , where x is the amount in Taka spent on advertising. For what values of x does the company make a profit?
Here,
Now, if the company makes a profit, then
As this equation (i) is greater than 0, so the value of the two roots must have different values in different intervals.
Now, from the equation (i), we have
The value of x is greater than 10 ie: x> 10
Or, the value of x is less than and greater than or equal to 0 i.e.
Because advertising cost can not be negative.
So, if the company makes a profit,
The values of .
576 Tk. would be saved when the breadth = 3 meter less
1 Tk. would be saved when the breadth= meter less
7,200 Tk. would be saved when the breadth meter less
So, the breadth of the room is 37.5 meter
Find the three digit prime number whose sum of the digit is 11 and each digit representing a prime number. Justify your answer.
Since the sum of the 3-digits is II and each digit represents a prime number.
So the 3-digits may be 2, 2, 7 or 3, 3, 5 because 2+2+7=11 and 3+3+5=11
Now using the digit 2, 2, 7 we have the prime number 227. Because other two numbers i.e. 722 and 272 are by 2 and thus are not prime.
Again, using the digit 3, 3, 5 we have the number 353 which is a prime number. But 533 which is divisible by 13 and thus 533 is not prime and 335 is divisible by 5 and thus 335 is not prime.
So, the three-digit prime number whose sum of the digits is 11 and each digit representing a prime number is 227 & 353. (Answer)
prove that a cyclic parallelogram must be a rectangle .
Let's break down the problem step by step:Cyclic Parallelogram: A cyclic parallelogram is a quadrilateral whose opposite angles are supplementary and all its vertices lie on a single circle.Parallelogram: A parallelogram is a quadrilateral with opposite sides parallel.To prove that a cyclic parallelogram must be a rectangle, we need to show that all its angles are right angles (90 degrees).Here's the proof:In a cyclic quadrilateral, opposite angles are supplementary, meaning the sum of the measures of the opposite angles is 180 degrees.Let's label the angles of the cyclic parallelogram as A, B, C, and D.In a parallelogram, opposite angles are equal. So, let's say angle A is equal to angle C, and angle B is equal to angle D.Now, if we add the measures of angle A and angle C, and the measures of angle B and angle D, the sum should be 180 degrees, because the opposite angles in a cyclic quadrilateral are supplementary.So, ( A + C = 180^\circ ) and ( B + D = 180^\circ ).Since A = C and B = D, we can substitute:[ A + A = 180^\circ ] and [ B + B = 180^\circ ].Thus, ( A = 90^\circ ) and ( B = 90^\circ ), which implies all angles in the parallelogram are right angles.Therefore, the cyclic parallelogram is a rectangle.
if then show that, a+b+c=pa+qb+rc
Therefore, a+b+c=pa+qb+ rc [Showed]
After travelling 108km, a cyclist observed that he would have required 3 hours less if he could have traveled at a speed 3 km/hr more. At what speed did he travel?
Let,
The original speed = x km/h
ATQ,
108/x - 108/x + 3 = 3
=> 108x + 324 - 108x/x2 + 3x = 3
=> 3x2 + 9x - 324 = 0
=> 3(x2 + 3x - 108) = 0
=> x2 + 3x - 108 = 0
=> x2 + 12x - 9x - 108 = 0
=> (x + 12)(x - 9) = 0
=> x = 9
Therefore, original speed 9.
solve:
