Question

दृष्टि रेखा (Eye line) को लैंडस्केप में कहां पर स्थित करते हैं?​

Answer 1

Answer:

यह रेखा पश्तून जनजातीय क्षेत्र से होकर दक्षिण में बलोचिस्तान से बीच से होकर गुजरती है। इस प्रकार यह रेखा पश्तूनों और बलूचों को दो देशों में बाँटते हुए निकलती है। भूराजनैतिक तथा भूरणनीति की दृष्टि से डूरण्ड रेखा को विश्व की सबसे खतरनाक सीमा माना जाता है।

Hope it is helpful.

Answer 2

Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/)[1][2] or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the displaced fluid.
