The idiom "as different as night and day" means two things are completely opposite.
Although we are brothers, but we are as different as day and night.
Given:
x = 1 / (√2 - 1)
To simplify, multiply the numerator and denominator by (√2 + 1):
x = 1 / (√2 - 1) × (√2 + 1) / (√2 + 1)
= (√2 + 1) / (√2² - 1²)
= (√2 + 1) / (2 - 1)
= (√2 + 1)
Now, find x - 1/x:
x - 1/x = (√2 + 1) - 1 / (√2 + 1)
= (√2 + 1) - (√2 - 1) / (√2 + 1)(√2 - 1)
= (√2 + 1) - (√2 - 1) / (2 - 1)
= (√2 + 1) - (√2 - 1)
= (√2 + 1 - √2 + 1)
= 2
Transitional devices are words or phrases that connect ideas smoothly in writing.
"Whereas" and "Finally" are used to contrast and conclude thoughts, making them transitional devices.
Object pronouns receive the action in a sentence.
In the sentence "She gave me the book," "me" is the object pronoun as it receives the action of "gave."
معراج کے واقعہ کے ذکر سورہ بنی اسرائیل میں آیا ہے۔
معراج کی رات نبی کریم ﷺ نے ایسے واعظوں کو دیکھا جو دوسروں کو نصیحت کرتے لیکن خود عمل نہ کرتے تھے۔
ان کے ہونٹوں کو لوہے کی قینچیوں سے کاٹا جارہا تھا، جو ان کے قول و فعل کے تضاد کی سزا تھی۔
Wave velocity is the distance a wave travels per second in a given medium.
It is calculated as Velocity (v) = Frequency (f) × Wavelength (λ).
سہیل بن عمرو اپنے بیٹے کو دیکھ کر کہنے لگا کہ اے محمد ! (صلی اللہ تعالیٰ علیہ وسلم) اس معاہدہ کی دستاویز پر دستخط کرنے کے لئے میری پہلی شرط یہ ہے کہ آپ ابو جندل کو میری طرف واپس لوٹایئے۔
The refractive index (n) is defined as:
n = Speed of light in air / Speed of light in medium
n = 1.5
Speed of light in air = 3 × 10⁸ m/s
Rearrange the formula to solve for Speed of light in glass:
Speed of light in glass = Speed of light in air / n
= (3 × 10⁸ m/s) / 1.5
= 2 × 10⁸ m/s
Learnt is the second and third form of Learn.
Learn means سیکھنا یا علم حاصل کرنا
A transitive verb required an object while intransitive verb does not.
"Whom" is correct because it is the object of the verb "met."
"Who" is used as a subject, but here, "I" is the subject, so "whom" is appropriate.
