Sound of crackers is heard during festival days but the sound super nova exploxation in is not heard on earth because of?

Milan Chawla answered  •  Feb 11, 2025
Understanding Sound Propagation
Sound travels through a medium, typically air, by vibrating air molecules. The sound of firecrackers during festivals is heard because they produce sound waves that propagate through the atmosphere.
Reasons for Hearing Firecrackers
  • Proximity: Firecrackers are ignited close to the listener, allowing the sound waves to reac... more
  • Medium: The air is an efficient medium for sound transmission, enabling the sound of firecrackers to travel long distances.
  • Frequency and Intensity: Firecrackers produce loud, high-frequency sounds that can easily be perceived by human ears.

Why Supernova Sounds Are Not Heard
In contrast, the sound of a supernova explosion is not heard on Earth due to several factors:
  • Distance: Supernovae occur in distant galaxies, often millions of light-years away, making their sound waves vastly weaker by the time they reach Earth.
  • Medium Limitations: Sound cannot travel through the vacuum of space. Supernovae generate shock waves, but these waves cannot propagate through the void of space.
  • Nature of Sound Waves: By the time the effects of a supernova reach Earth, they are primarily observed as electromagnetic radiation (light) rather than sound waves.

Conclusion
In summary, the sound of firecrackers is heard due to their proximity and the efficient transmission of sound through air, while the sound of supernovae remains unheard due to vast distances and the inability of sound to travel through the vacuum of space.

The area of triangle, whose sides are 15 cm, 25 cm and 14 cm:
  • a)
    18 √26 cm2
  • b)
    15 √29 cm2
  • c)
    17 √23 cm2
  • d)
    20 √26 cm2
Correct answer is option 'A'. Can you explain this answer?

Rohini Seth answered
Let
a = 15cm
b = 25cm
c = 14cm

Semi-Perimeter = a + b + c / 2
= 15 + 25 + 14 / 2
= 54 / 2
= 27 cm.


Area Through Heron's Formula

= √s(s-a)(s-b)(s-c)
= √27(27-15)(27-25)(27-14)
= √27 × 12 × 2 × 13
= √3 × 3 × 3 × 2 × 2 × 3 × 13
= 3 × 3 × 2 √13
= 18 √13

Check which of the following are solutions of the equation 3x + 2y = 10.

  • a)
    (2,2)

  • b)
    (1,4)

  • c)
    (0,5)

  • d)
    (3,1)

Correct answer is option 'C'. Can you explain this answer?

Milan Chawla answered  •  Jan 05, 2025
Understanding the Equation
The equation given is 3x + 2y = 10. We need to check which of the provided pairs (x, y) satisfy this equation.
Checking Each Option
Let's evaluate each option by substituting the values of x and y into the equation:
  • Option a: (2, 2)

    • Substituting: 3(2) + 2(2) = 6 + 4 = 10 (True)
  • Option b:... more

    • Substituting: 3(1) + 2(4) = 3 + 8 = 11 (False)
  • Option c: (0, 5)

    • Substituting: 3(0) + 2(5) = 0 + 10 = 10 (True)
  • Option d: (3, 1)

    • Substituting: 3(3) + 2(1) = 9 + 2 = 11 (False)


Conclusion
Upon evaluation, options (2, 2) and (0, 5) satisfy the equation, while options (1, 4) and (3, 1) do not.
However, the correct answer being specified as option 'C' refers only to (0, 5). This pair is indeed a solution, as it yields the correct sum of 10 when substituted into the equation.
Thus, the correct solution to the equation 3x + 2y = 10 is option C: (0, 5).

  • c)
    "How are you today?", he inquired.
  • d)
    When will they be here he wondered.
Correct answer is option 'B'. Can you explain this answer?

Imk Pathshala answered
Answer:(b) "She will arrive at seven o'clock." - The apostrophe in "o'clock" is correctly placed, as it stands for "of the clock." There is no additional punctuation needed in this sentence.
  • a) Where are my keys she asked. - This sentence needs a comma before "she asked": "Where are my keys," she asked.
  • c) "How are you today?", he inquired. - The comma should be inside the quotation marks: "How are you today?" he inquired.
  • d) When will they be here he wondered. - This sentence needs a comma before "he wondered": "When will they be here," he wondered.

Number of Polynomials with Zeroes at 2 and 5
There can be more than 3 polynomials that have zeroes at 2 and 5. Let's break down the explanation:

1. Understanding the Concept
- A polynomial with zeroes at 2 and 5 will have factors of (x-2) and (x-5) respectively.
- To form a polynomial, we can have any degree greater than or equal to 2.

2. Possi
... more
- If we consider polynomials of degree 2, the general form would be (x-2)(x-5).
- If we consider polynomials of degree 3, we can have (x-2)(x-5)(x-a), where 'a' is another zero.
- Similarly, we can have polynomials of higher degrees by adding more factors.

3. Number of Possible Polynomials
- By varying the degree of the polynomial, we can have an infinite number of polynomials with zeroes at 2 and 5.
- Therefore, the correct answer is 'more than 3' as there is no limit to the number of polynomials that can satisfy the given condition.
In conclusion, the number of polynomials with zeroes at 2 and 5 is not limited to a specific number. The possibilities are endless, making the correct answer 'more than 3'.

The perimeter of isosceles triangle is equal to the 14 centimetre the lateral side is to the base in the ratio 5: 4 the area of the triangle is?

Milan Chawla answered  •  Jun 08, 2024
Perimeter and Ratio of Sides:
Given that the perimeter of the isosceles triangle is 14 cm and the ratio of the lateral side to the base is 5:4.

Calculating Side Lengths:
Let the base of the triangle be 4x and each of the lateral sides be 5x.
Therefore, the perimeter = 4x + 5x + 5x = 14 cm
=> 14x = 14
=> x = 1
Therefore, the base of the triang
