Aisha Gupta answered
► If new values of x, y, z are x′, y′ and z′, and respectively then x′ :  y′ = 4 : 5, y′ :  z′ = 3 : 4
⇒ x′ :  y′ :  z′ = 12 : 15 : 20
⇒ x + y + z = 5000
⇒ x′ + 50 + y′ + 100 + z′ + 150 = 5000 x′ + y′ + z′ = 4700
⇒ 12k + 15k + 20k = 4700 k = 100
► x = 1200 + 50 = 1250
► y = 1500 + 100 = 1600 z = 2000 + 150 = 2150
► x + y = 1250 + 1600 = 2850

The period of oscillation of a simple pendulum of constant length at earth surface is T. Its period inside a mine is
  • a)
    Greater than T
  • b)
    Less than T
  • c)
    Equal to T
  • d)
    Cannot be compared
Correct answer is option 'A'. Can you explain this answer?

Anchal Maurya answered  •  Feb 18, 2022
A is correct answer because time period of oscillation of simple pendulum T =2π √l/g
it means time period of oscillation is inversely proportional to root of acceleration due to gravity.
and we know that in mine acceleration due to gravity
g' = g (1- d/R)
now u can understand that in the mine acceleration due gravity decrease that's why Time period increase..it means great... more

In the following questions, the symbols @, #, $, % and © are used with the following meaning as illustrated below:
'P @ Q' means 'P is smaller than Q'.
'P # Q' means 'P is either smaller than or equal to Q'.
'P $ Q' means 'P is greater than Q'.
'P % Q' means 'P is either greater than or equal to Q'.
'P © Q' means 'P is neither greater than nor smaller than Q'.
Now in each of the following questions assuming the given statements to be true, find out which of the two conclusions I and II given below them is/are definitely true?
Give answer (1) if only Conclusion I is true.
Give answer (2) if only Conclusion II is true.
Give answer (3) if either Conclusion I or II is true.
Give answer (4) if neither Conclusion I nor II is true.
Give answer (5) if both conclusions I and II are true.
Q. Statements : M @ R, R © F, F # L
Conclusions : I. M @ L
II. R @ L

Lia Ross answered

Sure. Here is the explanation for the answer option 'A' for the given question:

Statements:

M @ R
R � F
F # L
Explanation:

M is smaller than R (M @ R)
R is neither greater than nor smaller than F (R � F)
F is greater than or equal to L (F # L)
Conclusion I: M @ L
Since M is smaller than R and R is neither greater than nor smaller than F, it follows that M is smaller than or equal to F.
Since F is greater than or equal to L, it follows that M is smaller than or equal to L.
Therefore, Conclusion I is true.
Conclusion II: R @ L

Since R is neither greater than nor smaller than F and F is greater than or equal to L, it follows that R is neither greater than nor smaller than L.
Therefore, Conclusion II is not true.
Therefore, the correct answer is option 'A', which states that only Conclusion I is true.

Which of the following reactions of glucose can be explained only by its cyclic structure?
  • a)
    Glucose forms pentaacetate.
  • b)
    Glucose reacts with hydroxylamine to form an oxime.
  • c)
    Pentaacetate of glucose does not react with hydroxylamine.
  • d)
    Glucose is oxidised by nitric acid to gluconic acid.
Correct answer is option 'C'. Can you explain this answer?

Anoushka Chopra answered
The pentaacetate of glucose does not react with hydroxylamine. This indicates that the aldehyde in glucose is not free and is involved in the formation of cyclic structure. Hence, this reaction of glucose can only be explained by its cyclic structure. Thus, option (iii) is correct.
Option (i) is incorrect because the capability of glucose to form pentaacetate tells us about the 5 hydroxyl group of the glucose.
Option (ii) is incorrect because this reaction confirms the presence of a carbonyl group in glucose.
Option (iv) is incorrect because this reaction indicates the presence of a primary alcohol in the glucose.
