Why is Axiom 5, in the list of Euclid’s axioms, considered a ‘universal truth’? (Note that the question is not about the fifth postulate.)
Axiom 5 : ‘Whole is always greater than its part.’ This is a ‘universal truth’ because part is included in the whole and therefore can never be greater than the whole...

Does Euclid’s fifth postulate imply the existence of parallel lines? Explain
It may be argued that Euclid’s fifth postulate recognises the existence of parallel lines. If the sum of interior angles is 180° on both sides of the transversal then the...

You spill a bucket of soapy water on a marble floor accidentally. Would it make it easier or more difficult for you to walk on the floor? Why?
It would make it more difficult for us to walk on a soapy floor because layer of soap makes floor smooth. The coating of soapy water reduces the friction and...

Use Euclid’s division algorithm to find HCF of 441, 567, 693.
Solution: By Euclid’s division algorithm, 693 = 567 x 1 + 126 567 = 126 x 4 + 63 126 = 63 x 2 + 0 So, HCF(441, 63) = 63 So, HCF (693, 567) =...

Using Euclid’s division algorithm, find the largest number that divides 1251, 9377 and 15628 leaving remainders 1, 2 and 3, respectively.
Solution: Since, 1, 2 and 3 are the remainders of 1251, 9377 and 15628 respectively. So, 1251 – 1 = 1250 is exactly divisible by the required number, 9377 – 2 = 9375...

If Bohr’s quantisation postulate (angular momentum = nh/2π) is a basic law of nature,
We never speak of quantization of orbits of planets around the Sun because the angular momentum associated with planetary motion is largely relative to the value of Planck’s constant (h). The...

Is there anyone in your class whose language you do not understand, or who does not understand yours? What do you do in such a case?
Yes, few days back a boy from Kerala has joined our class. We did not know each other’s languages so we talked using gestures and enjoyed very much doing so.
