Explanation
Given y = 3: Step 1: Calculate y³. y³ = 3³ = 27 Step 2: Calculate y³ - y. y³ - y = 27 - 3 = 24 Step 3: Calculate y³(y³ - y). y³(y³ - y) = 27 × 24 = 648

Explanation
When a projectile moves upward , gravity acts downward. This opposes the vertical motion , so the vertical component of velocity decreases until it becomes zero at the highest point.

Explanation
20 men can construct a building in 40 days. Total work = 20 men × 40 days = 800 man-days. Time = Total work / Number of men = 800 man-days / 10 men = 80 days.

Explanation
Step 1: Calculate 8% of $600 8% of $600 = (8/100) × $600 Step 2: Perform the calculation = 0.08 × $600 = $48

Explanation
Vitamin K is essential for the synthesis of clotting factors in the blood. Its deficiency leads to prolonged bleeding or poor blood clotting.

Explanation
In the modern periodic table, there are 7 periods (horizontal rows) and 18 groups (vertical columns).

Explanation
NO₂ (Nitrogen dioxide) is a covalent compound , made of nonmetals (nitrogen and oxygen) sharing electrons. The others like (NH₄)₂CO₃, HNO₃, and AgCl involve ionic bonding either fully or in part (e.g., NH₄⁺ acts ionically).

Explanation
Dative bond : This is a type of covalent bond where one atom donates both electrons to the bond, forming a coordinate covalent bond. In this case,  NH₃ (ammonia)  (with a lone pair of electrons) acts as the electron donor , and  BF₃ (boron trifluoride)  (electron deficient) acts as the electron acceptor .

Explanation
John Dalton proposed the Atomic Theory in the early 1800s , stating that all elements are made of indivisible atoms. He described atoms as indestructible and identical for each element, laying the foundation of modern chemistry .

Explanation
A reaction in which heat is absorbed is called an endothermic reaction. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

Explanation
Step 1: Recall the definition of probability Probability is a measure between 0 and 1, inclusive. Step 2: Evaluate the options 15% = 0.15 (between 0 and 1) 2/3 ≈ 0.67 (between 0 and 1) -0.5 (less than 0) 0.01 (between 0 and 1) Step 3: Determine which option is outside the valid range -0.5 is less than 0, which is not valid for a probability.

Explanation
Step 1: Identify the pattern The differences between consecutive terms are: 32 - 29 = 3 29 - 24 = 5 24 - 22 = 2 22 - 17 = 5 Step 2: Determine the pattern The pattern seems to alternate between subtracting 3 or 2 and then 5: -3, -5, -2, -5 Step 3: Apply the pattern If the pattern continues, the next difference should be -3 (following the sequence -3, -5, -2, -5, -3): 17 - 3 = 14

Explanation
91 is not a prime number because it is divisible by 7 and 13 (91 = 7 × 13). A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers.

Explanation
Step 1: Let's denote the age of the youngest child as x. The ages of the 5 children will be x, x + 3, x + 6, x + 9, and x + 12. Step 2: Calculate the sum of their ages. x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50 Step 3: Simplify the equation. 5x + 30 = 50 Step 4: Solve for x. 5x = 20 x =  4

Explanation
A quadratic equation is defined as an equation where the highest exponent (degree) of the variable is 2 , like  ax² + bx + c = 0 . Hence, its degree is 2 .

Explanation
The total angle around a circle is always 360 degrees . This represents a full rotation or complete turn .

Explanation
In a sequence, each individual number or element is called a term . Terms can be identified by their position, such as the 1st term, 2nd term, etc.

Explanation
Given the speed of the car is 65 miles per hour: Step 1: Calculate the distance traveled in 5 hours. Distance = Speed × Time = 65 × 5 = 325

Explanation
Hazrat Jibrael ( AS ) delivered the Message to every Prophet from Hazrat Adam to Muhammad (pbuh). Izra'il – The Angel of Death, who takes the souls from bodies when people die. Israfil – The angel who will be present on the day of resurrection . Mīkāl _ is often depicted as providing nourishment for bodies and souls while also being responsible for bringing rain and thunder to Earth.
